DIY Through-Spindle Coolant Drawbar Bolt! | Shop Made Tools
Tired of coolant limitations on your manual milling machine? We were too, so we decided to ditch the limitations and made a game-changing through-spindle coolant drawbar bolt for our Zayer milling machine! We'll take you step-by-step through the process and show you the first test to see how it works! We’ll machine the custom bolt on the lathe, including threading and that all-important deep hole drilling. Then, it's over to the milling machine to mill the hex pattern and the drill the crucial through-hole for coolant flow. We also show making the rotary union joint that allows the bolt to spin freely while delivering coolant to the tool holder. Finally, we assemble the drawbar bolt and put it to the test, showcasing the upgraded coolant flow in all its glory. This is a DIY project we’ve never seen before, and it’s definitely going to take our milling game to a whole new level!
In this video we are using:
- Hafco TM-1740G Centre lathe
- Hafco BM-63VE Milling machine

You guys need to make videos quicker…. Your videos are literally my crack addiction in life.. 6 or 7 days in between is not good enough lol
Strewth! I’m on time for a change!! 😂 Whoop whoop!!! 🥳🥳🥳
Shop made quality, certainly not "DIY" Kurtis, 👌. Excellent addition to the mill, through coolant tools are very affordable now as you definitely know. I noticed you have a through coolant attachment on your turret mill. Lovely job both as always guys,have a great, and not to hard working weekend.
I have a suggestion what about a Y joint at were the coolant is so you can just turn a valve and you can chose air or coolant. Just a idea
I have seen something like it online somewhere - but I think it was another DIY adapter??? It's been years and I can't remember the details...
$45 in parts, a dash of world-class skill, some scrap metal, and you get an industrial tool/work of art brought to you through the magic of expert film and editing. Always impressive to watch.
Dont forget a few F*off trains and air compresssors thrown in for good measure. Lol
And Homie ....
Yeah...but he could have solved the problem using a $5 rubber mallet that he probably already owns to tap the union joint he bought instead. Would have had a better setup and saved 3 hours, $40 and the wear and tear on his kit. Just because someone can do clever engineering doesn't mean they pick the right solution. Just look at that fucking crane saga.
🤮
@@darkjudge8786 H8r
Always nice to see Kurtis running his little jeweller‘s lathe.
I'm a big fan of the 40mm pilot drills.
My grandfather left me and my father his lathe, and his uncals.?) jewelers lathe. I have been learning how to make watch parts and pens.
😂
@@danielcarter305 Sounds like your grandfather left you far more than his lathe....
@@danielcarter305 I always wanted to get a mini lathe for the Locksmith Shop .. I used to do a lot of lock repair, and even light welding, and odd ball repairs. But I sold the building and am retired now, .. I might get one anyway though!! :) (someday?)
As someone with audio processing difficulties, I am immensely appreciative of your consistent and high-quality subtitles. Fantastic work as always.
you're very welcome! Thanks for watching 😄
The added jokes in the CC are quite a bonus
Are you hard of hearing?
Are we right in thinking that the "out takes" take longer than the machining? Your videographer is a saint!
The words are hard to get out sometimes lol but he's getting better! 😅
@@CuttingEdgeEngineering Nobody would complain if you left a few mistakes in the video to cut down on restarting time. I think people would not care.
Nothing is better than seeing a notification for a new CEE video. You're videos truly get me through the week when it's been a bad one, or a good week. Thank you all so much for continuing to make videos for us. It means a lot to us that watch. Homie was very well-mannered around George and friends. He's such a good boy.
Hey mate thanks for watching We're so glad the videos can brighten your week, no matter what kind of week it is.
I think Homie may have dropped a couple WTF f-bombs while Kurtis was humoring George and friends, who appear to be as well tuned in to Friday’s as the rest of us. Really outstanding content K&K!
you wrote my feeling into word
The slo-mo wet shot was just missing Curtis dancing and Karen singing "He's a maniac, maniac!" 😂
Or "Sing in the Rain" would be another tune to consider.
Great ... now I'm trying NOT to picture Kurtis dressed in a cheesy 80's bodysuit complete with the wool leg warmers dancing under the mill!!!
Did you use a bucket too?? to pour over yourself ?? or make a tool to do that for you ?? 😉 🇨🇦🤓🤟
Great opening with the birds singing. Also glad to hear the "banana" reference again. Good to hear the Classics.
2 Banana... i was eating my Corn flakes....... now i have milk on my keyboad... .... .. good one! 😅🤣
😂 hahaa awesome we were hoping viewers might get a laugh out of that one
I spat out my beer an almost choked
I had a good chuckle! Love it!
@@CuttingEdgeEngineering It is a lovely measuring tool, and very useful as well, especially if you are going for close enough measures.
Speaking of which @CuttingEdgeEngineering when are they going to be back in stock?
Love seeing a workshop upgrade. Homey and the birds. Have a great weekend Karen & Kurtis.
Thanks Andrew great to see you are enjoying the videos as always. Say Hi to your dad for us
@@CuttingEdgeEngineering He said to say Hi to you both, he's watching the Repair shop I'll download ep for him for tomorrow
Homey and the Birds is a rock band I think.
I’m from Germany and have the cc on. It even translates the birds in German 😂
A couple of hours to make...It would have taken me a month and it wouldn't look anything like yours. You're a true artist!
Lovely, now your machine can double as a garden sprinkler in need. Love it!
The intro is not 'Snakes on a Plane', but 'Birds on a Crane' ;-)
One and only luckiest man on earth to be able to show all his abilities and expertise to his beloved Karen. Kurtis's jobs are always very satisfying. The way he explains every aspects of the machine and tools add another bonus to his work.
I love the way you start threading with the milling machine but always do most of the work by hand. I've watched a few guys thread holes with the tap chucked into a a drill. It always reminds me of how careful you are. I would think that tapping a thread with a power tool opens up the possibility of breaking a tap. Your attention to detail is always a pleasure to watch.
When he starts the tap with the machine it ensures the tap starts straight, in fact perfectly straight. 😊 Then finishes by hand, for safety. ✅😊
@@Jezeppi1 That's kind of what I said. I can see how it would be very easy to start a tam just a tad off perpendicular.
@@billmullins6833 That always sucks, but is super easy to get off axes with larger taps.
@@arthurmoore9488 Even though I have only needed to tap a couple of holes in my time I figured that was the case.
I don't know why but your machining videos are so relaxing. Love your channel!!!
I started machine work in 71, in a high school machine shop with about fifteen WWII nine inch South bends, a couple 16 inch and an Induma vertical mill with a CNC package. I never imagined I'd be using carbide inserts like I do, most of my work has been related to engines and fabrication of tooling. I really enjoy the ease with which you move from tooling to production work, it's been life's pleasures for more than fifty years for me. I just wish my own "pit bull" were as easy to get along with the wild life as Homeless seems to be. I'm surrounded by woods, and my Raven is constantly bringing home her kill. Seeing you feed the birds is an interesting perspective on Australia. This is one of my favorites!
That's about when & where I first used a lathe, too. Unfortunately, sort of, I went into software instead, and only ever owned a Sherline. On which I have made projects that would get instantly lost in CEE's chip pan.
I think homie is a staffy. I think it's one of the breeds that pitties were bred from.
We have a tame wild crow that politely asks to be fed. S/he has worked out that being nice is far more profitable than demanding attention like crows usually do.
@@davidelliott5843 Sometimes I wish people were smart enough to figure that out!
I'm glad you put the clamp on the coolant line and attached it to the machine. I knew a guy that was running a coolant thru setup like this. The bearings locked up one day while the spindle was turning about 2000 ish pulling the coolant line loose and spun it around the head at the same speed. Attached to the coolant line was a brass T 90 degree fitting which struck the operator in the head countless times before he fell to the ground. It completely caved in the right side of his head like hamburger.
2000 rpm without proper restraint is pretty risky. The normal drag would be fairly significant anyway.
Perhaps making a breakable failsafe part on the hosepipe connection if the bearing were to seize up. Rather a cheap snapped hose fitting than a damaged custom made unit or a damaged Kurtis. Cheers for a great video!
Well those sentences kept getting worse and worse +_+
Speaking of hamburger, I wonder if that's what K is feeding to the birdies.
@@pmiller7886 I concur. They make these pop connections that are designed to pull out if the hose gets snatched so it doesn't scythe once through the entire shop when something finally gives. As an added benefit, it'll let you know by way of a gentle coolant shower when it's time to change your bearings up there.
I would think it’s been discussed but, I would really like to hear you go over the educational and real world experiences that have helped get you this point. Just awesome Kurtis.
Dog, crazy birds, engineering and a very supportive partner....what more could a man want!!
"No union joint likes being hit with a hammer" - wise words indeed.
The slow-mo shot of the coolant helix coming through the face mill was a great piece of work! Nice shooting, Karen. Keep up the good work, guys, and give Homie some pats from us here in Indiana, USA.
Thanks for showing us how Kurtis manipulated the controls when he cut that thread. That was very interesting to see. Every machinist basically has their own style, and it's frankly much more interesting to see the controls being manipulated than to see chips flying. When you've seen one chip, you've pretty much seen em all, at least for that work piece. Please do more such shots of Kurtis driving his machines.
Your camera work and editing has just gone from strength to strength. In really enjoy your presentations, not to mention I learn things every time- I can be a big help for my son.
Fuck I got a laugh out of the banana calipers! It simply can't be overstated how important it is to have access to precision measurement devices in the workshop ;)
More crane content? Very much yes please. 😁
next week!
@@CuttingEdgeEngineering Crane is definitely not getting the Hayes assembly method then. Assembly is the reverse of removal is not exactly helpful.
Moe crane content
@@SeanBZA Assembly is the reverse of dissasembly - Until you factor in aged and deformed parts lol
Using the hex block was really smart. This is why I love this channel.
The collet's lock nut.
Very nice tool Kurtis. Coolant through tooling really does dissipate heat. When I had to bore 4 - 9" holes in a 6' x 7' x 16" press plate the coolant through tools made a difference, but still I had to rough the holes in one day, and finish them to size the next day, to hold a tolerance of 0.0002 for location & 0.0005 for size. I also find it amazing that these old machines can hold the tolerances. My machine was a 50 year old Cincinnati Gilbert Horizontal Boring Mill. That was 38 years ago.
Holey cow. That's tolerance levels where room temperature can cause problems!
That sped up footage with the normal sound is just the best thing ever. :) thank you for the extra efford.
That's nice work Big K! When I was last in a machine shop, we made parts for underground drilling rigs, and they were always wear parts, and always machined from 4140. I used to like working with that material. Was nice to hear George singing for us as well! Hope you have a good weekend.
Hey mate! Those underground drill rigs are no joke! Glad you enjoyed George's serenade, maybe he'll grace us with another tune soon. You have a great weekend too thanks for your support & super thanks 😎👊
Kurtis, you make engineering look like magic!! That the previous owner got by with threaded rod with a couple of nuts shows how far technology has come, and how you're inspired to make the most of your equipment. Match that with Karen's fabulous videography and I reckon you're the "Dynamic Duo of Engineering"!!! ❤
That slow mo shot of the compressed air ejecting the coolant through the tool was fantastic! Great work as always you two!
I love these videos so much. When my grandad died, he left me a myford ML7. You've given me the inclination to finally put it in my work shop and try and use it more. Thanks, Kurtis.
This is one of the things I like about this channel... Buying a part or tool isn't always possible, but if you have the capability to make them, great! I had no clue as to how the static portion was going to work and when I saw the bearings I was a bit surprised. Nice work! It's a rainy spring day here in Northern Germany and all the fruit trees are in full bloom! 🌼🌷 Have a great weekend and thanks for the video! 🍻
I chuckled when I saw the banana caliper. First time viewers would be like ... "what the f*ck did he just say?"
Its all bananers, thats why
Did you miss him call the chrome bar is 2 bananas in diameter? Us Americans will use any measurement system other than metric
Very funny long-standing combination gag+courtesy to American viewers, i honestly don't see how someone could be mad about it.
@@1oddtechMetric is just measuring with croissants
I love to see older tooling getting a make over and modernized, this channel shows it can be done and it doesn't cost a small fortune of buying it new. I look forward to watching every Friday morning. IM LOVIN IT!!!!!
Kinda crazy to think you're an operating shop but still manage to put out well done vids so religiously. I'd like to see a Day in the Life vid sometime
They did one a while back.
I would walk eight furlongs for a chance to meet Kurtis.
One of your best videos! Few things are more gratifying than creating something useful from material out of the scrap bin. In a past life, Kurtis, I'm convinced you were a Connecticut Yankee.
*Hi, friend! Thank you! we appreciate it! good luck!* 🙃
Nothing to say just an obligatory algorithm boost for the channel. 👍👍
I Love how Homey now Welcomes the rest of the gang, George & Friends, and knows its "feeding time"... pays no attention to the birds and waits his turn :)
I'm just an old carpenter and I have always been fascinated by your job .
Kurtis and Karen, your roll up your sleeves and get it done attitude is exactly why you have two successful businesses and will continue to thrive in the future. I get inspired by your videos as much for your work ethic as well as the amazing projects you accomplish. Peace from the states! 🇦🇺🇺🇸
There are times I wish I could share this channel with Dad. His thing was shop engineering, and interesting (often engineering) stuff in general. RIP 20-some years.
I know the feeling, that’s when it hits you… I have the same with aviation-related videos as my late father was an aircraft engineer.
It took me until you brought out the seals to understand how this thing would work. Very nice job and editing!
Homeless steals it in the end. Always enjoy the content and effort. Appreciated!
So satisfying watching scrap metal get transformed into useful tools.
Great way to start off the morning! The skills of Kurtis and Karen team so well in these videos it really is a treat to watch them. Be well and stay safe from Texas.
Many years ago in college I worked part time cleaning up in a machine shop. The take away...Don't leave the key in the lathe chuck! 30 years later I still dream of having a lathe and mill. Great work. Great Videos. See you next week.
I did the same once, the key hit the roof and scared the bejesus out of me. It is that once in a lifetime experience that keeps you focused from henceforth.
i went to a machinist school and all the lathes had a safety switch where you had put the chuck key into it before the machine would run.
@@anned8634 Good idea, better yet would be a taser that zaps you if you forget to remove the key. Pavlov's dog style conditioning. If it creates an second nature response of removing the key from the chuck all's good. Switches can break, doing the correct thing automatically is the winner, however it is learnt.
I absolutely love your content. It’s refreshing to see someone with a skilled trade showcasing their abilities and hopefully motivating some younger people to go to a trade school. Well done you two!
Beautiful sunrise, Karen. Sometimes it's nice to slow down and appreciate the world around us. Keep up the good work. You two put out some great content.
Good morning from Bulgaria 🇧🇬
Hi from Canada 🇨🇦 😊
Germany Here 🇩🇪😁
Poland watching😀
Russia 🇷🇺 as well
Good evening from Alpha Centauri.
Guy's that's an upgrade that was well worth doing , good sensible advise regarding drilling long deep holes so many people get it wrong.😊
Ohhhhh how I love the hyper speed tap tap tap edits. Curtis dammit Jim love your work. Spent 19 years in rapid prototyping industry. Around plenty of Bridgeport milling machines, lathes, Japanese pantographs. Just love manual machining. Such a skill. Such a craft. ❤
As a non-metric member of the community, I approve of the return to the banana system of measurement!
You bring a weekly smile to my face, thank you for that!
Greetings from Boise, Idaho! The "Michelangelo of Machinists" has done it again! Well Done, Sir! I kept trying to visualize the final product, but didn't see it materializing until the seals and bearings went in. Marvelous, Michelangelo! And Karen, I've watched your video work improve over the weeks and months and I am continually impressed with your artistry and creativity. The slow motion of the coolant coming out of the bit at the end of your video was really beautiful! Well Done, Madam! I've got to figure out a proper name for you! Thanks!
Not a machinist and it just blows my mind when you make these shop made tools and they seem better than the original designs.
Nice job Curtis. I like how you approach problems... "If they don't make what I need, eff it, I'll just make it myself"!!! Spot on mate!!!
New tool day is always a good day, even better when shop made.
We totally agree!
Kurtis and Karen, I can't tell you how much I enjoy your posts. As I have said before they just bring me back to working in my friends injection mold shop. We always had to come up with ways to solve problems with the tools and material we had on hand. 🙂
Love the slo-mo of the through coolant
Good morning from California's beautiful wine country! Another long week! Thank you, Kurtis and Karen. You guys make every week better. I have been kinda reluctant to tell you that you guys have helped me a great deal. I stoped taking my opioid pain medication 29 days ago and I have been watching CCE videos along with my favorite music video to keep my mind off of pain and drugs. Thank You grately Karen and Kurtis for all you do for us viewers!❤❤❤
Good luck Daniel, I cannot even imagine how difficult that must be. Love you buddy, my best wishes are with you.
Good wishes for your journey man ,getting off is not easy.theres a lot of fella's watching KZhead to offset the bad stuff,when you find a great couple of people to watch it makes it worth it , not forgetting 1 cool Staffordshire bull !
Hey mate! Huge congrats on 29 days off opioids, that's a fantastic accomplishment! We're so glad that our videos, along with your fav music, have been a helpful distraction during this challenging time. Keep it up mate we're cheering you on from here - Cheers K,K&H
I think you need to make some sheet metal guards to keep the swarf and suds off the floor
@@trevorgrimes7273 Guards? Uggg we men be.
Always enjoy watching your videos, I’ve been a plant mechanic since 1978 and even though we were taught machining techniques and having used a lathe during my career watching you just shows how amateur my knowledge actually is.
I love seeing organized tools being used and then put away in the correct, organized location. Calms my OCD
Karen. Your video production is spot on. You and Curtis make a great team and lets not forget Homie. I get great pleasure from watching your weekly videos. Truly a joy.
Kurtis it’s always amazing to watch you take a second hand tool and make it fully functional again. Karen thank you for videoing the adventure. In these times it’s a great escape. Thank you both.
Making your own tools always has some charm in it and I cannot wait to watch this one sipping my morning coffee.
Love the videos those birds sing so beautifully
Just brilliant.... everything from the commentary, the 'asides', the nature, the machines, the videography, .... the human essence. I really don't know why there aren't a minimum of 1 million subscribers by now. Thank you Kurtis, Karen, Homey et al... always a joy.
Kurtis you're not only a craftsman but also an artist, every time i am in aw, thanks mate!.
Always a beautiful sight when a plan comes together. And those birds are getting cooler by the week.
Banana caliper alert! Love those Aussie magpies, beautiful warble!
That's what Engineering, machining and a little ingenuity brings about, a well thought, absolutely useful and easy, problem-solver device. Works as intended and even better because it can sustain hammer blows, which a "ready-made" part cannot do
Rain drops keep falling on the mill ! Wonderful video with amazing skills ! Thanks for sharing !
I feel like I know George and Jeffrey personally. I love your videos, thank you very much!
Way to go with the arty-farty slow-mo water shot ... 😁
Hahaa thank you 😂
Homeless is so happy to show just how happy he is. Awesome job you two
Nice to see the return of the banana-gauge.
Always a good part of the day when a new machining video comes 👍😁
The only channel with bird breaks instead of advertising
I’m sure it’s no big deal to a machinist, but it always blows my mind when you thread a part in a lathe like that
It sure will improve cut quality and tool life, superb job as always! However, if it was to be sold as a kit for manual milling machines, it should come with an umbrela, raimcoat or something!
Good to see the old banana calipers are stil calibrated😂
Those birds are amazing. Love their calls.
Hi K & K and all your animal friends especially George and Safety Officer. Since being recommended by C&C Enterprise an American KZhead channel I have watched every vlog and am totally impressed with your channel and what you do. Please do more work shop tool making vlogs and even more on your Franna crane upgrade. Having spent 5 weeks in hospital after a failed heart operation your programme kept me going through all the troubles I faced as it took my mind off the troubles I faced. I look forward to 17.00 hours every Friday. Cheers Peter.
Beautiful singing in the intro as well. Happy weekend guys.
Homemade shop tools are the best way to save money.
Save time if the part is unobtainable or has a lead time of months.
KEE, You two are awesome talented couple. Always enjoy your work. Thanks, Boe 👍👍
I never seen a piece of steel try harder to escape the shop than that rouge chip coil did 😂 Awesome upgrade, looks like things are gonna be quite a bit cooler around the mill. Kickass work as always and I dont think a better look at machining, welding and repair exists on the internet. Cheers from Northern California 🍻
Homey and the Butcherbirds…..sound like a punk band ….. Happy Friday World. 🌍 xx
😂 that's a kickass band name
Great to see the return of the yellow bananaometer 🙂
Been watching for about a year now and I gotta say - Hats off to whichever one of you does the editing! I love the creativity in splicing time-lapse with real-time footage in such satisfying ways.
That banana caliper cracks me up every time you use it.
Beautiful job. That rotary union is a thing of beauty! I'll admit, I was a little worried that the long drill bit might break, but you made it look easy and even explained how to do it right. In my day, I never saw or used a milling machine with coolant. But it sure beats an oil can (that's the only coolant system I ever used). Thanks for the great video work, Karen. It's like you are in the shop. Thanks again, guys. Have a great weekend! Cheers.
Wow. Those opening shots almost make the Goldie look...charming. :)
Kurtis, when you said you wanted to make a coolant thru the spindle mod to the mill, you made exactly what I had envisioned, I'm glad it all worked out just like you had envisioned it, great minds think alike lol.
Loved the Slomo with the coolant running through at the end
Good morning from the UK 👋🇬🇧
