Hey everyone! Apparently some folks have trouble accessing the drawings. I’ve had multiple friends test them and they work for all of us so all I can say is try again. I cannot provide free tech support for all of you, I’m sorry. These are free drawings, keep in mind. I did my best to make them available to you, and hosting them costs me money. Please keep that in mind when setting your expectations of customer service.
Worked for me! Thanks Quinn!
"DO NOT SCALE. IF IN DOUBT, ASK" -- i.e. the download worked fine for me! Thanks, Quinn!
Failed to open in Acrobat first time. Redownloaded, unzipped and worked 2nd time, not sure what was different.
I tried downloading the drawings without actual intent to use them and it worked fine! Perhaps OneDrive senses your intent and selectively corrupts downloads from those who need them most?
@@LeshanaK wow, that'd be insidious! But since I didn't have intention to use them either, I can't falsify it! :)
I once worked with, what I will call one of the best manual lathe guys I have seen. When he ran into a problem similar to yours turning a long thin part. What he did to damp the vibration/chatter. Was to take his ballpeen hammer and hook it over the top of the stock. Than he could pull back a little or what was required to kill the vibration. The combination of the weight of the hammer and his feel on the handle worked quite well. This would also be a little safer than pinching with your fingers. Never the less you got a good result with what is usually a very difficult turning setup no mater how you do it. O just food for thought if you do make a follow rest. You might want to consider this. The normal rest is usually designed for right hand turning. In other words the stock will lift when being turned. So you will notice the jaw is on the top. If you make it for left hand turning like in this video, you might consider the jaw being on the bottom.
Cool idea!
@@Blondihacks Great video Quinn!! Building on what Peter said, I'd try to utilize the t-slot that is in front of tool and make a block that has a spring loaded bearing to act as a follow rest. My saddle doesn't have keyways in it, but I bolted a plate where the follow rest attaches to my saddle. Can't wait for the next video!! 🥰
Yes, normal steadyrest would not have worked for reverse rotation. You can make a bidirectional follower that fits in the teeslots, just adjust it in as needed.
And the Hammer Rest was thus born!
Enjoyed seeing those acme treads come to life. Wasn't sure if these feelings were accurate so I held a light up behind them. Yep, enjoyed it.
🤣😂
I need to order a couple of those transparent thumbs. They'll come in handy.
They come in left hand only !
Its always good to keep them ... on hand.
@@tlange5091 that joke wasn't called for. you'll be asked to leave the building if your not careful!!
I had one until I smacked it with a hammer. Turns out they're glass!
"chamfers are what separates us from the animals" .... PRICELESS !!
Quinn, Thank you for your kind words. I hope to get better at videos; however as of now I struggle. I really hope to put together some sort of video to be a digital “User Manual” showing all the uses of the Rose-Index. “Referencing, Rotating, Shifting and Flipping …. Plus the fact that it’s “Removable” really adds to the flexibility and ease of use. The Rose-Index really makes referencing and manipulating round parts easy. In your situation you mentioned not preplanning the use of a Rose-Index. You would have been fine by simply attaching it when you needed to reposition your work piece with a machinist square. Then you could remove it if you prefer. Even if you were to remove the work piece from your centering fixture you could have went to a flat surface and put a Rose-Index on and use your pin in the hole with gage blocks or similar on both sides of your work piece to get the pin parallel to the flat surface……Tighten the setscrew and you regained a reference. I goof up occasionally pulling a work piece out of a vise before I’m finished. Very rarely does it add more than a couple minutes to make or regain a reference by not preplanning or simply goofing up. Sincere Thanks and Best Wishes, Timm, Carl, and Anton Rosenthal
The only thing I would add to the "how to get something to exact length in the lathe" bit, for beginners, be careful touching off your tool to the end of your stock. If your stock is on the softer end the insert on the tool can sink right into it a good like 5-10 thou without you even really noticing because there's not much resistance. I generally use a 20 thou feeler gauge between the stock and the edge of the tool for things like aluminum/brass to get a known start point. Nothing worse than thinking you cut something perfect and it's actually nearly 10 thou undersized.
Paper touch off just like on your manual and or vert cnc for setting Z...
Hi Quinn, love watching you work and your sillyness. I was watching your 4 jaw chuck tricks and I wanted to share this with you and your viewers. About 30 years ago I worked with an 80 year old WWII vet. He was hands down one of the 3 greatest tool makers I ever knew. When he set up a 4 jaw chuck, he used 2 keys. He would use them on the jaws across from one another. Once he had a bit of clamping pressure on the part he would turn both keys at the same time in the same direction to move the part back and forth until he dialed it in. Then he would do the same on the other jaws. I never saw him use a 3 jaw and after I did this a few times I never did either. I hope this is a helpful little trick. Blake
Blondie, since you're the queen of the imperial fist shake, the term for older things is "it's an older (insert item here) but still checks out. " So for your list of videos it would be "it's an older playlist but it still checks out" I'm appealing to your inner Star wars nerd. Love the tool videos. Cheers!
Amazing work as usual, Quinn. The makeshift follow rest idea was pure brilliance. Wouldn't have come up with that myself in a million years. I suspect I might have to borrow the idea at some point.
When I hear an annoying car, truck, or whatever, I just say "Wow, I wish I was cool." But of course, all of us cool kids use sarcasm. Well done as usual. Another neat project has begun. Yay! Thanks, and Meow to Sprocket.
Whenever some clown drives by in his lifted truck with a hole drilled in the muffler revving it at the stoplight and thinking he’s a stud, I always say “damn dude, save some bitches for the rest of us”
@Mark Fergerson I had one of those trucks in my teen years, 67 Chevy PU with a built 327ci 3" dual exhaust blown out cherry bombs that exited just behind the cab and body to be just legal, was very fast stoplight to stoplight but the truck 4spd would top out at about 90. Load the cylinders with fuel one good rev and hit the spark button and fire shoots from both sides. That truck was fun.
@@LeonardRoberts I blew a muffler clean off the car doing that one night but, in my defense, I was VERY young.
I love that you never fail to remind us that the first operation in any lathe work is to face the stock; as is tradition.
The fist shake was a nice touch!
I'm so stoked for this build!
That little rest should be called the Lady's Chattering Smotherer.
I made one of these based on Mr. Pete’s design. Its been on my drill press ever since. I love it so much I ceremoniously discard the old drill press vice.
With making acme thread and nut thingies; I always cheat in 2 ways : 1. I make the thread way thicker than it needs to be (more rigid and easier in the lathe). 2. I always make them about 5 to 10 cm longer than I need them to be; I cut that off, do some milling on it and heat-treat it (I use mostly tool steels) and tadaaaa, got a matching tap :D ...
Great video, I love watching your projects take shape
Really great work. Very satisfying to get larger parts like this dialed in on small equipment.
Great inventing there Blondi. Looking forward to the rest of the build. Have a good one 👍🇦🇺
I always really enjoy seeing the tools you made in past videos making a cameo.
I love your channel. Regarding parting while using a tailstock center...I'm sure you've seen the Cutting Edge Engineering channel. Kurtis the machinist repair large excavating equipment. This include very large hydraulic cylinders. He cuts off the ends and welds in a new cylinder. To cut the ends he uses tail stock support and cuts through the existing welds until smoke appears indicating he has "almost" reached the inside of the cylinder. He then removes the structure and smacks the end with a hammer. Keep in mind that the rotating pieces are brought to the machine with an overhead crane (they are large and heavy). Pretty interesting to watch.
So much learning just happened. I can't wait to follow along with this project.
Really cool! Can't wait for a Follow Rest upgrade!
I have a similar problem deburring holes when making fingerholes on bagpipe chanters - my solution is designed for fingers: take a finger sized rod, wrap abrasive around it, and run it longways over the hole at 90 degrees to the part.
You did a great job on this and the use of the mag-base and brass for anti-chatter duty was neat.
Fantastic work as always Quinn, I to have never cut an acme thread you ingenuity for steady rest was brilliant. Thanks for the link to the rose index what a great idea. Thanks so much for sharing Cheers.
Awesome job on the Acme thread.
Yet another excellent video by KZhead’s most perspicacious machinist. Thanks, Quinn.
Bought two Rose Indexes the small one will be much used on models. Your casual mentions are golden! I keep a pen and paper handy while I watch your videos, jotting down those references, and then check them out a bit later. Thank you!
That was great, very educational! I just got done cleaning my new MX 210 v lathe, waiting on Amazon to bring a few things. I did did make a washer/shim for the stock tool post tool holder so that was cool. Thanks for all you do!
Very nice parts. I really like how you didn't cut out or ignore your failures to plan ahead. It seems like every one of my projects has several of those moments.
Really appreciated the comments about acme thread. Always knew what it was but never realised why it was.
Great video. Very clear narration.
That dampening rest was super cool and innovative. :)
Hi Quinn, as one of your viewers who never touched a machine tool in real life but is mentally preparing to do so one day I want to say how awsome you are. Also I want to suggest a topic for a video: How to read drawings? You show them in your builds and it is somehow clear that the information is in there but it looks superficially like a mess of lines and numbers.
I have actually touched a couple of machine tools, but touch is about the extent of it, I've never actually used any - but other than that, I'm in exactly the same boat as you. I'm waiting to move house somewhere with the space required for a small machine shop and Quinn's videos have been fantastic for me learning in advance! Help reading drawings would definitely help me too!
@@markfergerson2145 I wholeheartedly concur with your suggestion of taking a basic drafting course at your local community college. Well worth the few hours involved learning to "draw" what you'll later be required to "read". Combine it with a basic CAD class and you'll get your feet wet to use Fusion 360 or similar. Your employer might even spring for the cost and even if not some jurisdictions will allow a tax break. 👍🍌🇨🇦🕊️🇺🇦🤞
I’ve heard about your channel but now I’ve started watching it to get some tips using a lathe. Great channel!
Thank you Quinn, this has been on my list since Lyle's 1st video about them...
That's so satisfying to see that thread gauge fit so perfectly in those threads.
Really like the tips for future pros! Highly appreciated!
Amazing work as always!!!
I made a version of this project, adapting it to what I had on hand, which included the acme threaded rod and nut from an old Toyota scissor jack. You inspired me though, and next time I do a project with an acme thread I'll cut it myself. Thanks for making these informative and entertaining videos.
Nice one Quinn! The first threads I cut were acme. I knocked over mom's guitar and broke a tuning key. High school shop Teacher was awsome! 👍
I have learned so much from this channel. Thanks for your hard work!
Some of my favorite parts of your videos is one, your sense of humor but even more so you are not afraid of mistakes and use them as a teaching moment that we can all learn from - thank you and keep up the good work ( and some of the bad work )
Thank you I never got a chance to do metal work only wood work lol . Can’t wait for the next part thank you 👍👍
Great video. Thanks for showing using the gage to find the length. I'm probably the only one on here that this helped but as very new to machining I learn a lot from tips like this.
You are a born teacher Quinn. That was a nice project, thank you. Oh and, the drawing DL'd here no issues.
Once again, not a machinist and never will be, but your creativity and sense of humor are a bright spot in my week. Every week I laugh out loud at least once.. Thank you!
Very much enjoyed this video, and your humor is great.
"Your car isn't cool, its dumb" Best phrase ever
I was thinking same thing!!! Especially since Quinn is a race car driver!
You are an inspiration and make incredibly enjoyable parts and videos. I wish for you good health and all of the success you desire. Thank You and have a great day.
Nice tool build choice. We shared this video on our homemade tools forum this week 😎
The expert still makes mistakes, but knows how to recover from them. Your recovery was gold!
Always have my respect ! Down load of drawings went well.
I had a project that required acme threads internal as well as external on some 2” parts. Being so novice that I could barely spell lathe, I practiced on some 2” pvc until I was confident that I could do it. Turned out great and made me feel pretty good about teaching myself machining processes. Love your videos!!!❤
We're looking forward to part II. You deserve your popularity, Honey Chile.
Hi Quinn, Nice Acme thread cutting and I applaud your way of working through unseen problems. I once had to cut several 1 1/8" X 4 TPI internal square thread bushings to be pressed into 25 lb. barbell weights that were used on a antique telescope where the declination axis shaft was threaded 1 1/8" x 4. That was done on my 7 X 12 mini-lathe with a hand crank in the spindle. I made a silicon mold of a portion of the declination axis and then used low melting point casting metal to make a positive for a thread gauge. I was difficult on the small lathe, but did get it done and the barbells worked great as counterweights for the telescope. Once the point of balance was found, you snugged up the counterweights against each other and that held their position. You and the family stay safe.
You always do all the coolest projects. I remember when MrPete made the float lock vise and I was all enthused with it and was going to build one. Then I looked at what I have and it does the job very well and I just never did build one. If you get tired of being a programmer you can always get a job as shop foreman in a machine shop, maybe work for Tom Lipton. Keep on keeping on.
Spite based engineering is an excellent motivator.
Haha. Don’t tell Stephan. I won’t. Love your videos and explications. Thank you
I have those plans too,waiting to finish restoring my lathe. Be nice to see your build! I bought acme thread since I have the tap,yea the easy way out,but I need 2 of these in a bad way. Great video.
The one revolution setup when facing stock on the indicator is something all new machinst should know
From an experienced engin builder and tested point of view. All loud engins do is call cops and reduce low end torque in an engine. There seems to be a plague of them these days. Nice job on the threads. Used a block of wood to stop chatter once or twice myself.
I love that you redid the intro 😅 I also share your hatred for drill vices
I wish I had this lady,s skill and patience.
" . . . I failed to plan ahead . . ." Oy Vey, it happened to me too! Never mind. Good fortune in all your projects mighty Quinn!
The thread looks great, it must have been so satisfying! Clever recovery for the traveling rest problem too. There is so much of value to remember from each of your videos! I made a square thread tool out of a round piece of stock that was held in a hole in square stock with a grub screw so I could adjust the angle to suit the thread. Not my idea, copied from a fellow model engineer. The tool cut the thread, then broke on a spring pass while making the tap. Good enough but still a shame as I'm pretty sure the dims were not quite right (mine never are) so I probably wouldn't be able to cut a matching thread again.
I made this project it was fun to do . I didn't chase the thread. I used Acme all thread . You did a great job.
Would of been a lot more fun if you had cut the thread!
Love the Jank-o-Rest.
I know this comment will get lost, but here I go anyway! I have worked for a thread shop for almost 20 years. I have had good luck letting the chatter go, and on the last pass...speeding it up and it takes out the previous harmonics without letting the new ones develop. (that's the best way I can explain it)
Good tip!
Beautiful, very beautiful!
It was fun to watch - thanks
Another fine Acme product :)
Love your channel - keep up the good work! I'm a qualified Fitter & Turner in Australia but changed professions after 15 years and I haven't been "on the tools" for over 20 years. We were always told that ACME threads were used in precision machines as they would self-centre with no backlash, and self-adjust for wear when using half nuts or adjustable nuts.
Quinn, I love your show. I appreciate your knowledge !!! You come up with some real good solutions, and they work well !!! Give this a shot: I have been a tool designer/builder for over half a century. As I watched, and you talking about what you needed, an idea came to me. Sometime when you're needing another project, build this one and add it to your tools. Make a shoe to fit above the top of the tool-post you're using. Instead of using the standard allen set-screws to clamp your cutting tool in place, use longer all-thread screws. Set the shoe on top of the tool-post and use nuts on those all-threads to secure the shoe onto the tool-post. Build it so you have a swing-away upright, (hinged so the whole rig will lift off the work when not needed, just by pulling down the handle, like a slap, if needed, in case something happens, ie. Murphies Law #1, "If something Can go wrong, it will, and at the most inappropriate time!) Then build something that is (similar to a bench vice operation), a square hole with a threaded hole above or below it (you choose which). ((It only need 3" travel)) You want to be able to move a carrier that will have a clamp screw that tightens to the square bar running thru the vertical shoe-piece. This bar will extend to the back side of your work and have an adjustable up/dn square bar that your two follow bearings are running on.
chamfering an OD: Use an end mill (ball nose, if you want to avoid another setup) with a diameter close to the size of the OD you're chamfering on, and you just take the nose across the hole, and you should get pretty close to a nice chamfer.
Oh interesting! Good tip!
Nice work.....Thanks for sharing
Woo hoo! My Blondie fix!
Love the indicator tip for getting an exact length. I'm 100% the target audience for that, Got my lathe (crappy little import, but it's good to learn on) setup in the last two weeks and I'm just barely getting started working with it. Mostly just making upgrades to deal with it's deficiencies right now, but that's how I prefer it. You never learn how things work in depth if they work perfect the first time. Gotta have something break, or suck, and then scratch your head about how to fix it.
Great video as always. Time to get an electronic leadscrew. No more gear changes, I just love mine.
I use a drill press vice in my spray booth to hold a guitar holding setup when finishing. It's crap tolerances mean it doesn't get messed up by overspray, the rough textured jaws mean it holds the jig very solid, and the cheap price means I can replace it easily when it gets so gross I can keep using it. So, you know a second use for them does exist!
Totally feel you about the loud cars.
Very good work Quinn
Excellent job
Going to follow along since that was a 3rd shop project when I was in High school.
"poop knuckes"? As usual, you have taught us something of value! Just kidding, Thanks Quinn.
Very good content as always. I once tried to make my lathe cross slide lead screw I used a tough steel I had the same problems with the follow rest and my hss tool burnt quite instantly. It was a real pain and at the moment the project is suspended 😅.
Fun stuff and excellent video! 👍👊😎
Wow, what luck…You made the exact video I was looking for 🎉 liked and subscribed
I enjoy the treatis that you provide in your videos. Your approach is different and probably better than any other KZheadr. You are also very consistent in quality and quantity of yoru vids. Paul (Patreon)
Quinn, your squeeze bottle for the cutting fluid would be more fun if it was red and labeled with the word "ketchup" as wells a local diners name/logo screen printed onto it.
poop knuckles? thats a great one. watching the rest of video, and that phrase wouldn't leave my mind. great content. thank you
one of your more awesome videos!
Im simple, I see a new blondihacks video, and i watch it :)
Nice work.
Didn't know I needed that long of a caliper until I watched this video
Thanks for sharing!
It looks great
I like the clamp trick to keep the round stock from rolling while cutting it off in the band saw.
Ha!, I came here to scroll thru the comments to see if anyone else had mentioned that. Wasn't disappointed. Neat trick indeed.
