Making a PRECISION Machinist Jack || INHERITANCE MACHINING
Welcome back to the manual machine shop! In this video I’ll be prototyping a machinist jack with a few unique design features. The original idea comes from a very nice follower who shared his idea with me and I’m excited to share it with you as it solves a lot of the common problems with typical screw jacks. As always I spent a little time at the drafting board engineering the design (mostly) based around the tooling I had available in the shop. The final design is made from A2 tool steel and one of the key features that sets it apart are the knurled clamping collars that replace the standard jamb nut designs. Additionally there is a 2 stage threaded mechanism that uses a very coarse multi start thread for quick adjustment. Then ultra fine threads for high resolution allowing for precisely setting the jack height to within one ten-thousandth of an inch. Most of the work was done on the metal lathe as well as the vertical milling machine, but I used my previously made rotary table chuck adapter to maintain my references as I bounced back and forth between the machines. And it worked flawlessly.

I want to thank Art once again for the idea and inspiration behind this build. And thank you all for following along. Look out for the next upload on Friday November 11th. It's sure to be a real money saver 😉
Thanks alot for incorperating the drawing part aswell ..i Just love it ☆☆☆☆☆ Grtz from the netherlands Johny geerts
You should make a lapping plate
Thank you! You do amazing work and I really like the way you dealt with the coarse thread layout. Sorry that the grinder bit you and itself and the part. We all like to think, what a silly mistake, one I'd never make, but then I remember that I'm human and, like all humans, I excel at one thing - screwups. I have a long and tarnished history of screwing things up so, no, I have no room to criticize anyone else for just doing that which ALL humans do so well - oops, again :( Anyway, I think you've done a fantastic job of designing and making what is finally a useful machinist's jack! Bravo! :)
Awesome! When can I buy a pair?
Mate, you're flipping the name of the channel around with every project you make. From the tools you inherited to tool you're making that are very inheritable - I can see your grandchildren using this jack and being like 'oh, grandpa really gave us a nice tool here'
Just love watching this guy work, top job Brandon
I agree with you, Colin
Always funny when you realize youtubers you follow also follow other KZheadrs you follow.
I appreciate it, Colin!
Two radically different styles of creation, so cool to see tech KZheadrs overlap
Holy
My boss (who sadly passed a couple of years ago) insisted on making a machinist jack and a mallet himself for everyone who passed their apprenticeship. This is beautiful work
This channel is a diamond for engineers and machiners
Mechanics, like myself, too!
It guy here, love watching these..
This channel is a diamond -for engineers and machiners-
@@fastuncio 🤯 mind blown lol
Millwright here, love to see different operation tips and tricks when I machine in the shop!
You channel appeals to me for several reasons, including the use of your grandfather's tools, your hand drawings, your humility, and your calming voice and pace. Excellent video - as ever.
I appreciate that at a lot. Thank you
Absolutely agree... one of the reasons its so accessible to me. I really struggle when the presenter's voice races, the background "music-not music" is discordent to the point I just give up and walk away... which also means i loose out. 😢 This fella has everything dialled in just right.
I am a jeweler and of course I like precision processing. What you did and showed is a great example of dedication and determination. Then when you show all the mistakes you only become greater.
Thank you 🙏
I'm a machinist and enjoy seeing you make parts, but man, I think watching you make a drawing is so satisfying.
A good engineer, a good draftsman, a good machinist/toolmaker. Jack of all trades, master of many. Your work and talent are an inspiration to me.
You can make a gauge to allow you to test the fit of an internal multi-start thread one course at a time. You do this by making the external thread like normal, but then take additional cuts at other offsets to shave off all but one of the thread's starts. That'll allow you to use it to gauge the size of each course of an internal thread independently, as the gauge will fit with a correctly-cut course even if the other two courses are not yet to full depth, where using the full thread only tells you when _all three_ courses are at least the full depth (leaving you guessing as to which one is still too small).
That's an awesome idea!!
I agree with Sol. That is an awesome idea! Thanks!
I had to reread it 10x to finally get it. Clever idea I'm putting it in my toolbox.
I like your words, magic man!
@@impactodelsurenterprise2440 I still don't but i'm a noob
Your content is unbelievable, you are a huge inspiration to me, I've been a machinist for 15 years and I'm in the process of creating a similar shop setup, I absolutely love the videos and superb quality. God bless, and keep up the amazing work!
Absolutely my pleasure!
I really enjoyed the foreshadowing with the "Base Count: 1" early on. Well done. And bravo to Art and yourself for the excellent design concept and implementation.
😁 Much appreciated!
@@InheritanceMachining maybe you can reuse them for 2 other jacks that have a slightly larger external thread? Would be a waste to throw (almost) perfectly good parts away plus its always better having 2 or 3 instead of one :)
I love the honesty in your videos… Most people closely tailing perfection would be self conscious of mistakes… And as a mechanic who machines my own parts I see that we have one thing in common… Although I’m in no way tailing perfection, I’m prone to human error, and seeing you own it and correct it means ALOT… It’s the pat in the back I need at times when I mess something up and consider just outsourcing my machining! Thanks
Thank you. I figure some people will learn from the mistakes. And if not at least there is usually a good laugh involved. And for the record, my wife is usually the one to pat me on the back, or suggest a change of plan. We all need someone like that for sure.
My mother used to say, that to era is human, to really screw up, you need a computer
@@dirtfarmer7472 LOL you made an err.
@@scottdickens1454 Oops I stand corrected. Thank you Sir I do appreciate your help. I shall make that change
This channel is a diamond for passionate engineers, engineers and all those geniuses under the sign of steel which seems to be an extremely plastic and grateful material for machining, this is a championship in almost every respect, the world can be proud of people who feel more and communicate in an unusual way only for themselves that's another😊
Shoot, I'm a woodworker and I love this channel, even though a lot of the technical stuff is meaningless to me, it's incredibly satisfying nonetheless
@@thepewplace1370I'm not anything and I love it
I love how KZhead forgets that I’ve already seen this video. Watching it again!
Adam Savage would love this little treat of a tool!!!
Always impressed by the quality of the craftsmanship! 👏
Thank you 🙏
@@InheritanceMachining yeah, you Sir, also have great skills, absolutely impressive. The "eye-crometer" killed me though 😄😂
Just fantastic. It's a sign of a true worksman that you must first create the tools that you use to do the work. It's a privilege to be a part of this journey.
Thank you! It's been a pleasure thus far!
Hello Brandon I recently sold my machineshop due to health,that has taken a love of mine away leaving a huge loss to me mentally and physically. coming across your channel has inspired me to get my lathe and mill out of storage and at least get out in the shed and do what i have done all my working life. By the way wonderfully filmed and edited. Well done.
I'm glad you hung onto some machines for yourself. I'm still young in this game but I have a strong feeling once machining is in your blood there's no letting that go. Thanks!
It's been a while since I did technical drawings on paper. Glad to see the art isn't lost.
I am pleased to see someone drafting plans by hand
The precision that design allows for is absolutely insane! Once again another "side" project that turns into a main project lol. Great work man!
😁 It's a lot smoother than I expected! Thanks!
As a retired Architect and former engineering draftsman, very much enjoyed watching your drafting. It’s been many years since I used a drafting machine, lead holders, and hand sharpener. I definitely do miss hand drafting. Thanks for giving me a very enjoyable trip down memory lane.
This is a really neat project. I'm sorry things went sideways at the end, but I appreciate you showing us everything instead of pretending it was perfect.
Thanks. I wouldn't do it any other way.
Thank you Art for the amazing idea and a design that will surely revolutionize machinist jacks!. And thank you for machining it into existence. It was a joy to watch and definitely an inspiration to make my own. You rock!
:)
My pleasure!
Love the channel. I'm a robotics engineering student from Spain, and I can't express how cool it is to watch you machining and designing by hand (here in Spain we are taught design traditionally as well as digitally, so it's a great example of applying the traditional design method). It really is a learning experience for us students seeing you work, and with great commentary and production too. Discovered the channel recently but has already become one of my favorites. Amazing job man.
I really appreciate that man! Glad you like the channel and thank you for the support!
Not a machinist but channels like yours have inspired me to get a hobby lathe, just for the sake of learning the basics of the trade as well as being able to make my own little parts. Keep up the good work
If you can, you should go for it! It's one of the most fun machines to use. Not to mention useful
@@InheritanceMachining I'm an electrician by trade but have always been highly mechanical, I can do pretty much anything with my hands but have become more and more fascinated with hobby machining, especially since I like to prototype my own design and a lathe/mill would go a long way to making my designs look a lot less....scrapyard built. Thanks for the advice.
@@xsbiggy6349 I see you teetering on the top of the slippery slope of an expanding machine shop.......go for it and enjoy
@@TalRohan I fear I'm going to need a bigger shop..between woodworking, mechanics, electronics and other things that take up my space and time, I'll need a much larger shop lol
@@xsbiggy6349 Time! There are so many interesting things to learn, but so little time to learn it all. As I'm getting older, I realize how many things I would have loved to learn properly, like welding for example, and how fast the years are flying by!!! Space! I'm considering tearing down one of the basement bedrooms to make space for all those new toys I'd so madly like to own and operate! There's only so much I can do with my puny Chinese lathe and mill, and a decent lathe/mill setup eats up space faster than I can break a tap 🤬 Rigidity baby! I wish all of you hobby machinists the bliss of working on rigid machines!!!
I think the main difference between your shop, and most others, is your not doing it to make money, your doing it to have fun and connect with your grandad, and as such you can build these amazing things, as your not overwhelmed with jobs that need doing to put food on the table. 😊
I would not be surprised if that little accident came at the end of a long day in the shop. It's hard to know when you tired, amazingly enough pilots have the same problem. Great video once again, many thanks.
It's a blessing that, unlike with pilots, such mishaps hardly ever lead to loss of life in a machine shop...
You hit the nail on the head there. Thanks as always, Ant!
Hey there, for cutting multistart threads it's preferable to index by either rotating one of the changewheels or just removing the chuck and rotating it as needed (2 out if 6 camlocks slugs for a 3-start). You can feed in at an angle then... (If you have to use the topslide, use a dial indicator!) Also, I'd never rely on any kind of concentricity when using a drill and tap! Enjoy
Oh that's pretty clever actually. I'll remember that for next time. Also you are definitely right on the tap. I suppose I could have ground a little HSS cutting tool and guaranteed concentricity. Thanks!
Wow, what a simple yet brilliant idea!
@@hermit3400 can't take any credit, it's the standard procedure 😉
@@thanos_vgenis So standard, I'd never heard of it! Thanks for the tip.
"Woody Chucleson," eh? Love it. I'm always pleased to see you protecting the ways from catastrophic damage! 🙂 Your videos were excellent from the beginning, but somehow they are still improving. Enjoyed seeing this project very much. Thanks for all the effort you go into to share your experience and expertise.
My pleasure Bruce! I get a TO of good tips from the folks in the comments. Every once in a while they some stick 😉
Leaving the mistakes in the video is awesome. Mistakes are where the learning comes from, making it an "experience."
2:23 that's the coolest pencil sharpener I've ever seen I love it so much
I have been following this channel since your first video appeared only 9 months ago. The honesty, quality and commitment to follow through with what your grandfather left you shines out. I suspect it has been set up and planned for somewhat longer than that though. It's those qualities that have lead to almost 90K subscribers in that short time; for a machining channel. This episode has really flicked a button for me as I was thinking about how I might make some machinist jacks, but with left and right handed threads of different pitches to get the adjustments right. I'm looking forward to the next episode.
Thanks Bill. The plan for this channel is only a couple months older than the first upload, but I've had a lot of support from my wife who does this for a living. On your jacks, you might check out Adam the Machinist's video on differential threads. No need for left+right hand threads. I only recently learned of it and it very clever and simple
@@InheritanceMachining Yes, I'm thinking that 18 and 24mm would give a 0.5mm differential on the threads, which while not a small differential might just be enough. I also looked a metric fine but you still don't get much of a differential. If your wife does the videography and editing, she's really good at it.
Quickly becoming the best manual machining channel on KZhead, excellent work "warts and all" and your style of presentation is out standing !
I don't understand hardly any of of the process but it is so much fun to watch!
I have said this before. So many videos give the impression that everything comes out perfect & mistake free. We rookies at home then get frustrated by all the problems that are not shown on the video. The mistake shown at the end of this video is more important that the build video itself in my book. It's keeps viewers at home from getting discouraged when things go south when they see it happens to the best of them. Well done.
Thank you very much and thank you for the encouragement
I know that setting up the cameras and editing these videos take an absurd amount of time when you’re already putting the hours in on these projects but your attention to detail really shines. Each video does the respective project justice, superb work!
I really appreciate that. It is a lot of work for sure. Thank you!
This is incredible. Your hand drawings are somehow cleaner than the digital ones I've done in CAD softwares
😊 Thanks a lot!
Time to rework the surface grinder. Great channel. Thanks for the time and effort you put into it.
My pleasure. Thanks for the support!
Everynight right before i go to sleep and enjoy a IM video, literally therapeutic!
😁 my pleasure!
That is a really cool design - and of course a beautiful documentary of the process. Thanks Brandon and Art 👍
😁 Thanks man!
hey i got a late 1800s early 1900s Rivett backplate that’s beautiful that I broke I guess you call it the spindle off. It’s from a watchmaker lathe. I’m not good enough at machining yet would you be interested in fixing?
@@roonimacHi B, not sure if you are talking to Brandon or me?
@@CraigsWorkshop Brandon
Next time, use an indicator to get more accuracy on the adjustment of the lead for the multistart thread. Handwheel measurements are great, but it only takes a few seconds to set up the indicator and get it spot on.
And for anyone having trouble visualizing it - Blondihacks' Quinn uses the technique often. In this case, you'd mount the indicator to the cross slide, move the entire carriage in X (with the feedscrew still engaged so you don't lose clocking) until the indicator reads something useful, then drive just the cross slide the distance you need to offset the new cut.
That is a great idea. Ive never actually checked the accuracy of the hand wheel either.
Pencil, paper, imagination and brain aided design = perfection 👌 👏👏👍😀
You don't see many people drafting by hand here on youtube (or at least I don't) and it's really cool how neat the final drawings are.
I still have my drafting textbook from high-school
Mate, I love the channel, especially the manual drafting. Being a career draftsman starting on the board and table and eventually transitioning to CAD in college, I can say I love the more tactile feel of manual drafting and your drawings are mint! I have a suggestion for you to try within the mechanics of your technique, the knurling on the barrel of your lead clutch is to allow you to rotate the barrel as you strike a line, this rotation will help maintain a point on your lead longer and prevent flat spots from developing. Try it out and let me know what you think. Keep up the fantastic work, and remember if it's worth doing it's worth overdoing.
I didn't notice if he wasn't rotating the pencil barrel, but yeah, it's something I remember being taught and still do for even noncritical cut marks on material.
Thank you! I do use that technique on occasion. Not sure if I captured it or not in this video.
Love the final shot with the Audel's Machinists and tool makers handy book. The entire Audel's series of books are full of clearly written and illustrated (most of the time) priceless tips and tricks for the auto didactic. And they covered nearly every trade related subject like carpentry, plumbing, sheet metal, you name it.... even electric automobiles from the early 1900s.
Oh I wasn't even aware it was part of a larger series. Now I'll be on the lookout!
A lot of people would like to have a nice jack like that. I’m not a machinist so that’s not me. Nice work. Thank You Sir
And a perfect timing with the end of my work week ! Dang you’re a boss 😁 Thank you for such a content :)
😁 Well, thank you for the support!
I was pulling into my shop when I got the notification you posted a new video. What I have to do today can wait 21 mins . I have to say I look forward to every video. It’s hard to say which parts I love the most because every aspect is top notch. Not sure if you do this full time but if not it won’t be long before you do. If you ever need any machines let me know. I would glad give you a huge discount. Dan
😁 You are very kind, Dan. Thank you! Also that's a generous offer. Do you have any pantographs lying around?
@@InheritanceMachining I will find one. Believe it or not I see them more than you would think. There was one that came across my lap recently but I had to buy an entire room to get it and there was nothing to be desired so I had to pass.
Watching the hand drawing brought tears to my eyes
I know nothing about drawing or machining but really enjoy watching your videos.
I was using my cheapo machinist jack yesterday and I was thinking I should may a v-block style top for it. Ya know, for supporting cylindrical things. Maybe you should make one, so i can see how it's done!
Absolutely. Im thinking a v-block and ball tip anvils would be good followups to this projects.
A V-block anvil will eliminate your ability to use the fine pitch threads, unless you make the V-block section in such a way that it rotates freely on top of the anvil. One way to do this would be to drill a small hole in the center of your existing anvil, and make a separate V-block attachment with a centered pin on its underside.
I come for the machining i stay for the side projects
It's uplifting to know you can depend on a good jack. Working with good tools lift up your spirits.
Thank you for showing your mistakes as well as how you tackle them. Something you hardly ever see. Can’t wait for more!
I love these side projects! I am curious though, what sort of 'main projects' do you intend to work on down the road? Most of my machining is ultimately towards making bits for my motorcycle. I was curious if you have some sort of external project you eventually want to direct your machining powers towards? To be clear I could watch side projects forever, and also toolmaking forever! I'm just curious if there are any cool cars/motorcycles/tractors/ect lurking behind the scenes.
I think this was a main project
@@indian.techsupport yes, I mean for the machine shop as a whole though. Granted it’s totally possible that machining itself is the hobby, in many ways that is the case for myself. But I try to justify it with crazy notions of saving money on my other hobbies by making parts myself (never the case haha!) I am just curious if he has anything cool he wants to make parts for. Lol
@@MatthewMenze yeah, i think since he doesnt have to spend that much money for new tools, its easier for him and also by making videos
@@indian.techsupport I’m not sure, the more tools I get and the more I make the more I want to buy. The videos may help offset this, but I suspect it ultimately only fuels the tool addiction hahaha. I’ve got a beautiful Wells Index milling machine waiting for us to build a home shop around, and it already has me in fear of all the tooling I want to get and make for it hahaha.
😂 That's a fair question. All of these smaller projects are definitely feeding the hobby itself. But long term I do have many larger scale projects I'd like to make. Different machines, machine upgrades, probably a car in there at some point. Right now I'm sortof tacking a lot of the smaller bits to fully outfit the shop and also hone my skills. And also get the process down for what can be reasonable achieved in one video. Anyway, I really appreciate the support!
Ah nice, my favourite machinist channel has a new video... so I'll stop working and start watching :)
Me too :)
Three start internal thread! Respect. Also liked the tip for matching knurls. Thanks.
Thanks!
My Brother. You made me cry in Both Joy and Pain. Your intelect and humor is pure candy. On Great Shoulders We Stand! Lead the Way.
How deep is the damage on the magchuck? Will it grind out?
It feels like maybe 5 to 10 thou so should grind out. but that's going to take a while 😂
Use your precision flat stone to remove any burr that was raised from the impact, and leave the divot to serve as a GIANT!… GLARING!… REMINDER!… to be more careful in the future. For the same reason, the chowdered-up grinding disk should be wall mounted at eye level as near to the machine as possible. Maybe on a nice decorative plaque.
@@InheritanceMachining, why remove all that metal if your Grandpop paid for it? Just knock off the burr.

this is my new favorite channel. something soothing about watching raw metal becomd something.
Being an old highschool machinest with a nice shop, this is therapeutic to watch for me. Remembering all the fun I had letting my creative mind flow. Thank you for making these videos and giving me some nostalgia in my darker days.
Absolutely fantastic. No music, beautiful hand drawing and drafting table, no music, a wonderful personality, and no computers. Did I mention no music.
Kudos for sharing the minor surface grinder tragedy. Anyone-professional or hobbyist-who says they haven’t turned the wrong dial or turned the correct dial in the wrong direction is lying. And such mistakes always seem to happen at the worst possible time. We learn from our mistakes or, if we’re lucky, from the mistakes of others. Thanks for sharing yours.
Absolutely. That wheel will be hanging on the wall by my SG as a reminder.
Thank you so much your beautiful use of pencil and drafting board took be back to high school (i'm now 64 ) and my love of tech drawing class. No CAD for me.
Concentricity: the quality of having the same centre (as circles inside one another). Antonym: Eccentricity a circularity that has a different centre or deviates from a circular path. Man !!, there is just no accounting for the uber cool world that lathes and machining opens up to enjoy. Simple yet deeply layered. Heaven for a mind craving detail, accuracy and thriving on complexity. Its so exciting to see a whole new world opening up to me and I feel so bloody lucky. All new language, concepts, challenges, problems and solutions, possibilities, opportunities... I dont, but I almost do wish I'd done a fitter-turner apprenticeship instead of an electrical apprenticeship. Oh well, never to late to have a second childhood I guess 😆 Thanks !! Much appreciated !!
You're a real machinist Brandon. You're the real deal Bro ! 👌
😁 Thanks! But there's way more to learn still!
its good to see professionals doing errors. as a learner nearly every job I do is full of errors. now it makes me feel more confident in my work. everybody can stuff things up and it happens. 😀
Thank you, but I am by no means a professional 😂
I love machining videos! My dad was a tool make my entire life and he would always bring home things he made and show me blue prints for projects
You're a true talent in so many different ways... humbles the best of me to see such great work.
This has earned its place among my favorite machining videos, the design steps taken are so clever! I had to share it half way through!
😁 That is quite an honor. Thank you!
Is it just me or does anyone else enjoy the drawing section of the video the most it's just that the drawings look so cool, like I'd actually put them on my wall cool. Keep up the good work man. 👍
Thanks Aaron!
This is like meditation. And engineering. In one. Keep up the good work!
😁 Thanks!
One of the coolest, smartest thing I’ve seen in a longer time
You have got to be the best problem solver I’ve ever seen as a machinist 👍
Very nice video. What a joy to watch someone use a drafting board! Reminds me how magical I thought drafting tables were almost 40 years ago when I took a drafting class in high-school.
When I was an apprentice I was tasked with making a few sets of machinists jacks. I used 2 start and 3 start acme threads. They were the smoothest and strongest jack I've ever used in my 15 year career. Wish I still had them today.
Now That’s A Machinist Jack. Art for the win. Circling the wagon and adjusting tool height to compensate for deflection is used frequently with my mini lathe. The trick being the calculation of how much to compensate is black magic and a lot of guesswork and try try try.
NEVER compromise accuracy for precision! Always opt for ACCURACY. Thank you again. I really love your videos. Thank you for sharing. I am disabled, but I appreciate your effort and teaching. Thank you again:
My pleasure!
Screw jacks were one of the projects when I was learning to machine 30 years ago. While these are MUCH fancier than the ones I made, the instructors had incorporated acme threads for adjustment and a ball bearing under the floating cap to always keep it level with the work. Love your design!
As a retired machinist I love watching this channel. A true craftsman at work. I built a similar set of 4 jacks about 40 yrs ago for use on a large boring mill. Used 1” X 8 on the sleeve and 5/8” X 10 on the anvil. Turn the sleeve and get .125 per turn. Use the anvil and get .100 per turn. Turn the sleeve and hold the anvil and get .025 per turn. No special taps required. I read an old Mechanics illustrated article about a house jack that used the same principle.
the hand drawing of the piece is what kept me watching, awesome
you are a lucky man to have had a great grandfather, and even luckier to carry on his love of machining
That jack is a piece of art. Well done.
That was an outstanding Machinist Jack, well-made despite the tumble at the end. Having said that I would still love to have it. I am a retired Marine Engineer and an indentured Engine Fitter and Turner, I did my apprenticeship at H.M. Dockyard Devonport, Plymouth UK. I have a workshop with lesser quality tools although I still poses a lathe and mill along with a heck of a lot of other tools/machines. So, for me to congratulate you on a job well done, is quite a complement as I don't often give them out. Thanks to Art for his great idea and thanks to you for producing a splendid Machinist Jack.
a good engineer can make it. a great engineer can make it work 👍
Love that lovely people are donating slugs to you, mate. Weird wonderful world. 🥂
It really is 😊
Not only is that a fabulous idea that you and Art came up with, and the part itself is beautiful. But the fact that you took the extraordinary amount of time to film this and show everything that you did to such a level of detail is an absolute gift.
My pleasure! Thank you
You make the the tools, parts, pens, etc how I would if I had my own lathe, and mill but alas I do not. I started my machinist, welder, fabricator life at 13 working for my uncle at his shop, then was taught by one of the best teachers I've ever known when I got kicked out of normal high school and had to go to a continuation High school where I met Mr. Smith who changed my life and really put me on the path I took as he taught me everything he knew about welding and machining. I love you work man you strive for the same thing I do and that's to make stuff as clean and perfect as you can. I just wish I inherited a machine shop lol.
Thanks, man. While you didn't inherit a machine shop, you did have a great mentor which is even more valuable in my opinion. It's hard to find people who want to teach what they know. Keep it up and do the same for someone else someday.
I'm just a mechanic but I love watching your videos. Well done brother.
I could watch you hand draft all day. Amazing work!
😁 Thanks!
My master once told me that you never put both hands on both axis at the same time, AVOBE ALL with the grinder. It's just too easy to cross your references unconciously and make a mess. You only touch the Z when you have to increase it and leave it alone while you're grinding. I did that mistake once in the lathe. Of course I crashed, totaling the piece, breaking an expensive insert and leaving an awful scar on the chuck. Lesson learned! Also, I want to congratulate you for your channel. It's just amazing how warm, well explained and well filmed your videos are. You're growing fast and it's totally deserved. You even have the "big ones" like Colin Furze cheering up your work. Thank you for bringing this awesome videos, I dream of having a shop like yours one day. In the meantime, I'll just enjoy your videos! :D
That is great advice. I typically don't do that except when I am getting a touch on the part (as in this instance). But may need to change that practice as well. I'm honestly amazed at how well the channel is being received and growing. And a lot of great folks in the comments, yourself included. Thanks as always Raúl!
This channel gives me a therapeutic sensation from old times past when I was a mechanic in the food industry. Sometimes I miss the lathe, the mill and the TIG-welder. And the millimeter precission gives me a pleasing calm. Keep the video coming.
😂 Yup a scissors type knurling tool is on my list (and rising in priority). Thanks as always Ron!
Love the drafting table and hand drawn prints. Brings back memories
One of my favourite videos so far, it just looks so satisfying to use.
😁 It makes quite an awesome fidget toy
I’ve just started machining on a CNC mill and this would be a god send. Maybe in a few years when I’m trusted to make one I will!
Really enjoyed watching you draw the design with the K&E drafting machine. Really took me back to my high school vocational drafting class with my best friend Alan, and our teacher, Mr. DeWitt, circa 1976-78...
This might become a new tool for machinists everywhere. Granted, I'm not a machinist, but I do understand how most tools work. Kinda like a gift from my grandfather.
As a hobbyist machinist I really appreciate you including your thought processes and the "courage" to be honest about your mistakes!
I wouldn't do it any other way! 😁
