- I finally bit the bullet and removed the stuck Collet Chuck from my Index Model 40 Milling machine. And I made some Brown and Sharpe 9 taper tooling. I also broke my lathe, and then fixed my lathe.

Hi Jeremy, Love your version of gardening with the needle de-scaler and plants.
Had to do it sooner or later. I was totally holding my breath as you were boring that out. Literally at the point where I was thinking "ok, time to stop and just buy a reamer", you stopped and bought a reamer. 🤣
I was actually expecting you to find significant damage to the surface inside. I was thinking there was a good chance that it had spun in the taper and friction welded itself in place. But it looks like it just had some corrosion.
Thanks for showing not just what went right but what went wrong. That helps those of us watching avoid wasting our time on simple mistakes, so we can instead waste our time on new and innovative mistakes.
First time viewer here. The second you chucked an old drive shaft into your lathe I became a subscriber. My kind of guy!
Anchorlube.... I put that s**t on everything 🌭🌭😁😁
That's my life in a nutshell, 2 hour project turns into 3-1/2 day machine repair saga.🤣
Me too!
Did you try tying a string between that chuck and the door knob? Slam the door shut, and it should have popped right out. 😊
Well done Jeremy! If it’s any consolation it took me 20 years to finally get the screw on chuck off my lathe. Cheers mate, Stuart 🇦🇺
I never got the screw on chuck off my Colchester, ended up selling it with it still stuck (did some major turning with intermittent cut that tightened it up way too much) It did make enough money to pay for the lathe though plus, I couldn't ship it 4,500 miles
I have an INDEX model 45. Searching for info is how I found this channel. Subscribed immediately!
I've been looking forward to this repair since you first introduced the milling machine with the stuck collet chuck. Thanks for sharing.
Well done! That was indeed a lot of work, but I feel like this is one of those things that, a couple of months from now, you'll think to yourself, "How the hell did I get on with that collet chuck for so long?"
Now the funny part is, you'll probably end up making a new B&S #9 collet chuck for some other project down the road. At least you won't get that one stuck!
Also, I get unreasonably excited to see someone using a J.T. Slocomb micrometer. I've got a large collection of them, and rarely see them in the wild. (If you ever need/want to restore yours, I've got a video detailing the process)
I’ve got two Slocumb micrometers, the other one appears to be older (and has smaller markings on it). It’s one of those tools that, for whatever reason, just has the “right” feel to it.
1:25 - Scissor-style knurlers are one of those tools that you will not regret making.
True, they beat the plain knurling tool by a galactic margin...
Thanks for taking the time and effort to make these videos, they are really great and I learn a lot from you.
At least you made the most out of the setups with the extra tooling. That's a good start towards the eventual compliment of stuff. But yeah, I can just imagine the number of hours bleeding away between beginning and final sigh of relief....
I can feel your pain with that spindle repair!!!
I am constantly lightly cleaning my 55 with my brown and sharp 9 taper.
That bs9 taper has done wonders to the spindle accuracy since I got it.
Nice recovery, and I really like the idea of repurposing the axle shafts and other parts. Great job.
long time coming, but sure worth waiting for. I think you did a great job, and thank you for sharing ;-) cheers from Denmark
That was great from beginning to end. I love the use of 'junk' material to build useful things. BTW your narration is excellent. Subscribed.
This is the video I’ve been waiting for. Well worth the wait and even better than expected. Bravo!
Not sure if anyone has seen them, there are a couple of other fly cutter builds on TH-cam….. 😂 This is definitely one of the most entertaining! Thanks Jeremy
Inspirational! Fantastic finish with all the tooling fixes and such. I feel less worried about my 5c holding devices addiction. Thanks!
My comments are as follows: 1 excellent project and sub-projects. As a fan of your channel, I knew this day was coming, and I'm so glad you fixed that old machine rather than doing the sensible thing. 2. Your use of dog shit material from the river bed never disappoints. That steady rest is Gucci as hell. 3. Your power hair @0:11 inspires me to be a better and more potent man. I mean, I've worked my ass off much of my life, but that hair and those pseudo chops help me see I could be more. Thank you for that, sir, and thanks for another great vid.
🤣🤣🤣
“That was tough”, but oh so worthwhile. Well done for a brilliant result. 👏👏👍😀
Looks like breaking the lathe was the best thing for it, maybe I need to break mine 🤔 looks like the mill is now a whole lot more versatile as well. Doesn't turn out that well very often! Also I love your use of the rustiest piece of metal on the planet to make your drawbar.👍
“Broken” is a spectrum. It went from “a little broken” to “too broken.” There’s a lot more that’s a little broken that hasn’t forced me to fix it yet.
Another great video Jeremy 👍l really enjoyed watching your videos as l find them very informative and entertaining, you seem to be able to make almost anything from nothing but scrap. Keep it up mate, Gary from the UK 🇬🇧
gotta love the model 40. Someday I want to restore mine, but I want a white seamless machine, possibly powder coated. I use mine a lot.
This is the side project video that finished up with a great flycutter and some other useful stuff.
I bet that was satisfying when the last stuck bit came out of the quill , just the cylinder you managed to machine out was awesome.
Whenever I have had to spend a lot on a single use tool, I always feel justified when it goes the way it should and even better when it finds other uses ...Ive had my share of wishing I hadn't bought the tool cause something else went wrong right afterwards ....or worse the tool broke.
It must be great being able to use your mill to it's full capability finally.
Damn Jeremy, and here I was thinking earlier this week am I the only person in the world that struggles with "everything I own is worn out and has to be fixed to use it". Nice to see I have company! Did you ever determine exactly why the taper was stuck in there in the first place? Nevertheless nice job and now you have full capability restored to the Index. That's worth the time any day! cheers
From what I can tell from other people’s experience, these tapers like to get stuck sometimes (probably a combination of over tightening and leaving it too long). Even in normal use, it takes some force to get the tool out. It seems like there’s a reason they don’t use this taper any more.
@@JeremyMakesThings The shallower the taper angle, the harder it bites. Ask any flat bottomed boat owner who's run aground.
I don't know what im watching or what you're saying half the time when you're talking about machining.... but you make it entertaining and I am learning some things. Cheers.
I'd watch you for the dry humor alone...
I agree!!!
Big win.
Congrats.
What an adventure!
You are a brave one sir. I was on the edge of my seat, even having read about this adventure on Craig’s Workshop discord! Nothing like seeing it, I was so enthralled and just HAD to see the end!
I didn’t check what you did and didn’t try… but my first thought was improvising a firing pin and end cap to fire a blank cartidge on it. (Consider a 1 mm vent hole, use a face screen etc etc and don’t forget a wooden cushion for it to land on in case of success).
Anyway… you succeeded as you did and I enjoyed watching.
Looks like fun, subscribed
Very interesting. Nice work
Ah the joys of owning and working with old machines, you got some awesome-looking finishes on some of those parts, nice outcome. 👍
Nice job friend. You showed tenacity.
Nice job Jeremy!!!
Nice work on repairing that spindle! That was a difficult operation.
Thanks Quinn!
On my fly cutters I always grind a notch in the bit to put at lest on of the set screw into. It won't slip out. I sure feel safer using it. I have seen them fly out, probably why the call them fly cutters. Cheers!
Dude you actually fixed everything!! Conglatulations! Amazing video and talent
That is the exact same method I used to remove a jammed morse taper sleeve from my mill spindle, right down to buying the correct reamer to finish off the job. Nicely done!
That was a lot of work, but I enjoyed it!!! Thanks1
I have seen bushings / bearing housings being removed by welding a few beads on the inside. When the filler metal cools the base metal shrinks. Neat trick. A possible solution after boring out the spindle.
Absolutely beautiful work!! You show such a variety of skills, your fun to watch.
Honestly really happy for you to have gotten your mill spindle back
OOO WEee I was looking forward to this vid ever since you mentioned the collet chuck was stuck
you did a way nicer job removing a stuck taper than I did, I cocked up 1/3 of the circumference of the tapered bore but luckily only half way the length of it so it's still plenty precise
Dude, you never cease to amaze me!
Well done! You handled Murpheys law splendidly!
Your channel name is real, jeremy *infact* makes things.
You missed the opportunity to pretend the fly cutter got stuck in the spindle at the end of the video. Otherwise, quite interesting. Can't wait to see more of the Jeep project.
Happy Birthday man.
thank you
Your shaper as a backup machine saved you to fix lathe which in turn fixed your milling machind. Good collection, though i wouldnt have gone through the pains of making such a big fly cutter. At the edge of your machine's capabilities? Otherwise great repair job wish i had an inspection camera like that
Jeremy you call 2 1/2 years procrastination, I still ain’t put my 45 back together. Still some of the close up video you shot will be helpful when I do. You must be well satisfied with all that effort.
When my collet got stuck like that I used a large bearing puller with success.
I hsd a similar priblem in my lsthe.
The xhuck was stuck on the spindle nose.
I solved the problem with e lobg lever for turning , heating the ouside with a inductive heater an coolibg the inner part with cold spray ....
A tight-fitting copper bar (tapered maybe) that sticks out 5-10 cm inserted into the collet, then submerging the lot in liquid nitrogen might have been an interesting experiment :)
I’ll give you that one- I didn’t try that, and there’s a (slim) chance it could have worked.
Had a similar stuck shaft, only this was due to aluminum corroding inside chrome moly steel. Seat post on a bicycle. Tried freezing the aluminum with dry ice and even liquid nitrogen.
Ended up dissolving it with sodium hydroxide.
I tried that in vain
Jeremy, new guy here and i love your channel, Thanks.
Wow. It took both of your lathes to get the chuck out. Glad it went well.
Great job, thanks for posting. Take care.
Some heat to get that Chuck out or if you can get a thing we use for body work we call it a slap Hammer it's a weight on a slide and you like a hammer you hit it down and it'll pull dents out of the car pull bearings out
If a tapered fit device spins it can friction weld itself into the receptacle.
I think yours might have have a small area welded in, basically you have to machine it out and re cut the female taper (as you did).
My big old drill press has a morse taper that refuses to come out for the last few years... hopefully I can get it out without as much work (famous last words) 🤔
skill is the great equalizer. you have arrived.
My Sheldon No. 0 horizontal mill has a B&S 9 spindle and the arbor was absolutely stuck when I got if after sitting for decades. Wedges from opposite sides did the trick easily. Hold a hammer on one side, strike the other and repeat a few times...like separating a drill chuck from an arbor.
Yep, I tried wedges. The should on the back of the collet chuck was curved and made it hard to get them to seat, so they just bent out ward.
@@JeremyMakesThings I can see that. When you put the carbide in the vise I was thinking you were going to square that up for wedges at first...might have been too much of a gap though for normal wedges. Stuck stuff sucks!
@@chrisbartolo4308 With the spindle removed, he could put it into a bored throug block, sawed in half, and put one half on an anvil, the other on top, and strike it with a big hammer, turning the spindle in the process. Like when you remove steering ball joints, only the have a much steeper taper. Same principle works for drinking glasses stuck together - hit them on the side with a wooden kitchen utensil, and they come right apart without damage.
Nicely done.
The BS #9 reamer costs *$220* 0.9″ Small End, 1.155″ Large End, 1″ Shank, 6-1/8″ Flute, Brown and Sharpe Taper Reamer #9
Well done, I have a pulley stuck on a motor shaft that might get similar treatment today if my 8T home brew hydraulic press doesn’t persuade it to comply.
That was as stuck as the backplate on my lathe was stuck to the spindle. I ended up turning it off in my mini lathe. That 5" diameter backplate took many hours to get rid of 5 thou at a time 🙄
thats a great one! thank u! 👍
Can't imagine the cost of what you have made in this video, if you go as to purchase, but sure the quality would not be as good. The time spent is irrelevant I suppose, the achievement is far greater, fantastic work as usual
The reamer alone costs $220
Jeremy, that cutter is mo’ fly.
😄
you should use a follow rest on long pieces
I can't believe how stuck it was! I will try to remember not to bitch when my BS9 is tough to remove
It seems there’s a reason they don’t use this taper any more
@@JeremyMakesThings true that
That model T drive shaft is pre-nuclear steel worth about $15/lb
Back when they didn't know how to engineer for planned failure, so they just made it damn good.
Ball joint separator
Yep. Tried it.
@JeremyMakesThings I also used ac refrigerant once to shrink a fitted part. Nowadays you can use canned air upside down. Also pressing it further in can make them easier to remove. It causes the micro ridges to become misaligned.
I have only just come across your channel - Subscribed.
By the way, with the awful noises made by the drilling - there is a kind of "toothpaste green" lube that kind of anchors itself to surfaces which seems to help - I forget the name of it just this minute.
I’ll look into that. 😆
Would have tried making a tie rod removing tool that is just a U shaped Wedge on a handle that fits it.
I tried several wedge like devices. The shoulder on the chuck wasn’t square enough to get them to work.
Lots of work but a great result 😀
15:14 OW, I had this on almost full blast because my speakers just don't convey voices as loud as everything else for some reason, and that... like a flashbang for the ears
I would suggest calling Dr Gupta he is my gastroenterologist and his fingers are long enough to feel for and remaining bits lol 😂
Beau travail 👏 💪👍
Totally unrelated: Could you put that slick tapping head you have in the tail stock and use it to quickly tap parts on the lathe?
I think you could tap with it, but it wouldn’t reverse on its own. I guess you could reverse the the to back it out.
I'm assuming you tried a puematic hammer down the draw bar hole? At the same time another hitting it sideways?
Yes
Did you try a torch? The only time it fails for me is when there's a pin somewhere. Btw, you can probably buy a new Bridgeport spindle and quill for not much more than the new reamer.
I did try a little bit, the two problems with it were: 1) it wasn’t possible to heat the spindle directly, since it was inside the quill (and the bearings) and it wasn’t possible to get the spindle out of the quill with the collet chuck in it and 2) getting the spindle too hot would risk ruining the temper on it.
Drilling through and using ice spray to shrink the holder could have worked.
Yeah, that was several fights in one - but great bounty of results, too!
Love the caveman tailstock!
perfect!
Exactly how many pieces of riverbank have you employed in your shop?
A LOT!
I would suggest that hard steel not be used for the tailstock guide pin; those pins are designed to shear under excessive load.
Like the flywheel key on a lawnmower engine
@@erik_dk842 Exactly!
What part of your mill did you destroy? Didn't see anything like that. Looked like a good repair and brought it back snuff.
The collet chuck. It had made itself a permanent part of the mill.
great job
nicest flycutter on the internet 👍👍😎👍👍
I'm sure that #9 reamer will pay for itself in time
Did you try Liquid nitrogen :)
If that model T steel it’s pre atomic steel it was worth more lol
great video
