There are people with horrible skills, then people with some skills, then people that are good , then people that are really good and then there is Stefan's level . Amazing work Stefan 👏👏👏

[@zumbazumba1]

eeeh he is just really good ,insane pecision would be range of tom lipton from ox tools.

[@strykerentllc]

@@zumbazumba1 Tom is excellent but Robin Renzetti works in jaw dropping detail when it comes to overall skillset as a toolmaker. Robin is also a master in his craft with eyeball deep nerdology. Stefan is excellent in his own right and has many more years ahead of him to grow. That being noted, Stefan is VERY good at his craft and shares much insight, sans any "bob's your uncle".

[@laiquocbao2565]

Oh wait, you forgot Peter from Edge Precision, he is the Yoda of CNC machining world

[@planaritytheory]

@@zumbazumba1 Is Tom Lipton really considered "more precise" than Stefan? Do other people agree with that? Genuine question. I am too ignorant in machining to have an opinion.

[@turningpoint6643]

@@planaritytheory Imo Stefan is at least equal to Tom, but they both excel in there own slightly different areas.

[@barkerxsa7002]

Given that the request was to return to a "good" condition, one can extrapolate that Stefan's definition of "good" would be most peoples definition of perfect. Watching these uploads is like being invited to a world class lecture, the most enjoyable and educational content on KZbin.

[@moonpup6262]

I was going to ask how that was spelled

[@WilksGRendai]

It’s the European standards version of the ubiquitous Tom Lipton “Dingus McGhee” 😁

[@robmckennie4203]

Obviously you can tell Stefan has seen it, but for anyone who hasn't I do want to suggest people look up Robin Renzetti's video rebuilding his mill spindle, all of Robin's videos are excellent

[@HanstheTraffer]

That video will humble the greatest of precision veterans...(mill spindle is very different than a drill spindle though)

[@chrisstephens6673]

Indeed his videos are excellent but far too few of them.

[@TimCrothers]

A suggestion for an option other than the double nitriles I learned from grilling use - cotton gloves inside the nitriles. It provides a really nice insulation layer while maintaining the dexterity you need and still costs next to nothing.

[@alialy210]

You should make carbide bladed scissors for your abrasive cutting needs. Would be a great project video.

[@gasman2558]

carbide is good but cbn is better ;)

[@DonStinger]

actually you can buy carbide tipped scissors from medical supliers.

[@jimsvideos7201]

I saw ceramic-edged ones at an electrical supplier; they're for cutting the kevlar jacket on fiber-optic cable.

[@dsfs17987]

@@jimsvideos7201 you don't really need ceramics to cut kevlar, just make a quite rough 90 degree grind on decent steel scissors and they will cut kevlar just fine, rough texture helps holding the fibers from slipping out of the V, 90 degree grind is the magic ingredient they won't last as long of course, but in a pinch it works very well on this tough bendy stuff

[@HanstheTraffer]

Why not just go to single crystal diamond scissors? Cost maybe?

That is one happy spindle, getting the Stefan Gotteswinters special spa treatment😁 Nice rebuild Stefan👍

[@RRINTHESHOP]

Really nice job on the Quill. That will be a really nice drill press now.

Stefan rebuilding a drill press spindle so it can be used for brain surgery :-) Brilliant Stefan

[@Sketch1994]

If you see what drills they actually use to perform brain and spine surgery you will be dissapointed. I didn't know how crude these surgeries were until my spinal surgery failed and I ended up learning the nitty gritty myself (in the time of the internet one can just attend medical specialty schools like neurology, neurosurgery, radiologist and orthopedic without actually being a student there as long as you don't perform surgery on anyone who is alive) after a dozen doctors failed to see the obvious signs that other doctors were too ashamed to admit they missed too.

[@DolezalPetr]

@@Sketch1994 they just use a normal drill people use in their garage

[@Sketch1994]

@@DolezalPetr Pretty much yes...just in stainless. And while I thought it's more like precision machining it's more like contractor's work...

Excellent education in the finer parts of machining and tool making! Thank you for your constant precision and for your detailed explanation and commentary! You are the finest machinist/educator I have found on you tube and I aspire to achieve 1 tenth of your skill on my own projects!!!

[@icecreamtruckog3667]

I missed hearing the happiness perfection giggle. Great job.

[@heikolang335]

Hi Stefan, Since I recently purchased a TB 10, I came across this video two days ago. By now I must have watched at least half the videos you have posted. Which means on Monday I‘ll be through.... very impressive whats possible in a basement shop. You really accumulated some serious equipement. I‘ll definetely get in touch with you about my spindle.

[@stevecanny1583]

Beautiful job Stefan! It's worthy work to restore a well built machine to full service, preserving all the work the original makers put into the rest of the machine and allowing it to continue to serve :)

[@skipgoryews1356]

yes ! what he said ! we are so fortunate to have you on KZbin. You are always in some topic discussion around our round table in our shop thank you for that. regards Skip

[@thedabblingwarlock]

Thanks to this video, I learned two things, besides how to put a drill press spindle together 😉 1. I learned why and how you preload bearings on a shaft. 2. Faber-Castell makes more than art supplies. I never knew they made stuff for machinists. I happen to like their PITT brush pens.

[@robertdebusk6157]

Very nice job on the rebuild. Thank you for taking the time to bring us along, and show us how a craftsman repairs a spindle. That drill press has probably never been so smooth. As always, Thank You for the lessons learned. Take Care and Stay Safe. Bob

[@bcbloc02]

Funny I got bit by the hot bearing a few videos back when I was working on the valve grinder spindle and now you got the same thing. Makes me feel better about my oops. 😂 Might you should have ground a little off the end so no danger of the spindle end bottoming out before it reaches the taper? Seems that could possibly be an issue.

[@larryblount3358]

I thoroughly enjoy your videos. Seems each time I learn something new. This time it was the hint about steel wool. I was never taught there was a good way in a wrong way. Thank you. Your pointer long time ago about CRATEX has improved many a part!

I took an old junk Taiwanese drill press that someone was giving away. It had a Jacob's taper 2 1/2 on the spindle. I successfully converted the spindle over to JT6 and put a keyless chuck on it. Great usefull tool in the shop now. That was my first time to use the taper attachment that came on my Logan lathe.

Stefan, I am always amazed by the high quality of the work you do! You may have exceeded NASA specifications on this spindle. I cannot thank you enough for what I am learning from your videos. I completely understand your comment about how much fun this work is. Sadly, I think we will be losing a great deal of the knowledge craftsmen like you possess since too many children today are afraid to get their hands dirty. :-(

[@gerhardweber1331]

Nice Job! I did the same thing for my old Flott, but on the lLathe with a support grinder. It was OK, but not as sophisticated as your job. An old and very experienced mechanic that was reparing old drill presses once told me that the deformation of these tapers normally come from a slipping chuck on the taper. When the chuck slipps, the higher points get warm and harder than the rest of the taper.. When the chuck slips again, the harder points will remain and the softer parts will wear a bit more. You can't remove the hard tips with a simple honing stone then and you need to grind it with a grinding wheel, like you did.

[@frrapp2366]

yes i caught a 1 in drill bit in a work piece and bent our drill press (visibly), yey that back bearing was pretty rough sounding, the axle bearing on a john deere 4430 uses a hot install course its a 4 in axle shaft, cool job my first time watching

[@tombellus8986]

Stefan, very nice work as usual! Thanks for sharing. Joe

[@wambsganz8]

Thanks I enjoyed this video. I also figured out what to do with my old NiCad Cordless Drill. I have a old bench top Canedy-Otto drill press with external taper. Someday I will get around to restoring it. I measured run out with a indicator in a chuck relative to the bed and it was pretty much spot on. The only problem is the chuck sometimes falls off because the taper is a little beat up. I am checking eBay because I am thinking about replacing with a internal taper because I have a lot or taper shank drills. Thanks again.

Are you sure your Emco lathe bearings aren't angular contact bearings?

[@howder1951]

[@markamy357]

Ahh, you can’t beat a bit of spindle building good practice to put the world to rights. I have been lapping a myford type m lathe spindle which was lightly scored with a split aluminum lap with excellent results but maybe if I had a precision flat stone I would not have had to make a lap.

[@bradthayer6782]

Where’s the “wow” emoticon? Nicely done!

[@soundlimit300]

Nice work Stefan.

[@kevinsellsit5584]

You should have mentioned that the spacer washer was directional and putting it on backward in a preloaded application would be catastrophic.

[@ScrewDriverxxx]

Very enjoyable watch. Really good info on the wire wool! I never realised it would have a cutting direction.

[@stephendeakin2714]

Thanks for video, I've got a milling machine that runs hot, suspect spindle bearings are worn out, will have to get around to replacing them.

[@craigywaigy4703]

Tip: When deburing/polishing a journal, shaft, etc, then us a 321 block, or a parallel with a piece of wet and dry abrasive paper(with/without light oil) instead of a stone. Works faster, cleaner and saves on irregular slip stone wear. 321 blocks are best as the holes act like reliefs and holds the grinding sludge away from the interface.

very good job stefan..thanks for your time

[@brutusyt2842]

Very nice repair and video, as always ;-) 2 years ago I had a similar drill press (TB-10, the small brother) with the same problems, bent spindle and bad bearings. The bearings used in this spindle were oddball Type E15 and type BO15, angular contact bearing with brass cage. (apparently also called magneto bearings). Perhaps useful info if the owner ever wants to upgrade to angular contact bearings. Or perhaps Flott changed to using 'standard' size bearings more recently. The one I have seems to be quite old.

Stafan's drill press is the only drill press in the world that has less than 1um runout

[@prodigy750]

I usually use a C-clamp to crack the races, it work very well and is fast

[@tobyw9573]

Good move rounding the spindle/bearing surface, inner bearing races will conform to the diameter and surfaces of the shaft more or less.

[@DudleyToolwright]

Can the drill press be used as a vertical lathe to rehab the taper in situ? Maybe by fixing a mating Taper to the table and covering it in a fine emery cloth then running the spindle over the top of it. Thank you.
