Bronze Thrust Bearings for Shaper Tool Slide
ฝัง
- เผยแพร่เมื่อ 27 มี.ค. 2018
- This is some continuation footage from SNS 209. Here I'll machine some bronze thrust washers to help take up the end play of the lead screw and provide a better bearing surface for the shoulder to press against. The addition of these simples trust washers will help eliminate anymore wear on the original casting.
I may experiment with an actual needle bearing for this later on once I locate the proper sizing.

Another great video Adam, I love it when you are measuring up the piece and then out comes "Grandad's micrometer" or "Dad's old ...." it really adds that touch of providence to your work and shows the pedigree of your family. You really are a pleasure and delight to follow mate
Am a maintenance mechanic by profession and do a little of everything: welding, machining, plumbing and electrical. Have two Bridgeport clones, a small Clausing and 15x 60 Lansing lathe, and OLD Brown & Sharpe No. 5 grinder at my disposal. Have learned a Lot by watching your channel for couple of years. BIG FAN!!!
Hal Austvold same here.
I like your close-up stills at the end. Good focus, lighting, and composition - calendar worthy!
Was thinking the same thing. Excellent.
Thanks!
abom, you never cease to amaze me with all your knowledge, both as a machinist and a video producer! i havent seen a video youve made where ive lost interest! as long as you keep making videos, ill keep watching :)
You should inscribe those washers with your name and date so in 70 years the next person can tell when the original repair was made. Great work. My wife and I love to watch you videos because you are a natural in front of the camera and your camera angles give much context to your explanations. Keep up the good work and God Bless you.
"Give it to Abom, he can fix it. He can fix anything!" Thanks, Adam for another great video. Cheers.
Engraving machines from WWII era had bronze thrust washers on all three axes inside and outside to be replaced as needed which explains how I could use them in the 1980's-90's-2000's. America's preeminence in precision machining was what propelled the winning of that war,and all subsequent decades of prosperity.
I think it would take me 30 minutes to center that bronze rod up and I think you did it in less than 15 seconds. Thanks for “letting me in your shop”!
Hi Adam, yeah, that "I don't know where I put it down" thing happens in my home & shop so much, it explains why I have multiples of things located in various rooms so I can always find one with ease!! Nice repair!!
Lol Same thing happens to me. Be alone sitting on the ground working, lay a tool down and it magically teleports 20 feet under a box or something as soon as you take your eyes off it.
Anytime I lose a part I had in my hand, I always check the bathroom. At least half the time, there it is! Thanks for all the wonderful vids, Adam.
Those little washers look like cymbals, that would make an awesome little mini drum set haha
Always admire the people who keep their shops as clean as their houses. Hats off to all who fit the profile. Nice video Adam.
Really appreciate the mid week boost. Thank you.
There is nothing about what you do for fun or for a living that doesn't fascinate the shit out of me. I could watch you all day sir... (And when I was binge-ing your channel back in the day that was exactly what I was doing.) Zero regrets on that
Never gets old watching you true a piece on the 4 jaw. You Are The Man on 4 jaw!
Hey Abom, I must say your dad and family must be so proud of your setup and carrying on the family business with so much passion! keep it up ol scout!
I learn so much watching you work, but mostly it's like a meditation seeing you go through your process.
A bit of mid-week machining to brighten up hump day! This virtual apprenticeship is TH-cam at its finest.
Really good work Adam!!!! Enjoyed watching.....Thanks
Nicely done Adam, now that you made a new key you will probably find the original. Happens all the time.
Adam, your videos are the best, thanks for sharing, ow the anticipation is killin’ me to see your G&E Shaper running and the step down installed and seeing it being used.!.!.!.
Funny how we shoot for making a certain part one way and we end up with another like your perfect Belleville Washer that works perfect for your situation!
15.32 "put an angle on it aswell so that it parts the piece off and leaves the nub on the material", aahh, that is the gem for me, just about to grind a set of tools make a set of parts and that is something I have not come across before and will be so useful. Thank you so much, looking forward to working that out.
It is easy to set a tool or a part down and completely forget where it is. Like you, it is so nice owning some of my grandad's measuring instruments, tool bits, his lathe and his drill press. He worked as a machinist and at home as well, just as you do, after he retired.
Almost forgot to say: very good solution!
Good stuff. Looking forward to seeing the nut emerge.
Excellent modification. I like the way that you’re keeping the machine as original as possible. It would have been tempting to add thrust roller bearings, but this is, to my mind, the better way.
Yeah, the shaper's shaping up!
Hi Adam, Big Fan of your stuff! For thin washers and the like, take a look at Chris's work over on Clickspring. I use his "superglue jig" all the time and it works great.
Hey Adam, check the washing machine, dryer or your clean pants for the key. Looking forward to the nut and final assembly of that part. No kidding about where to find the key; we used to lose change and found it one of those three places (washers, nuts and even dollar bills, too!), Greg.
Mom always said, "Look under your bed!"
Looks done right now, looks like it should have been made with bronze replaceable bushes in the first place, but then given its nigh 70 years old maybe not eh! This whole head restoration is going to make the shaper I think, I was itching to tear it down. Well done Adam.
Great video work Adam. Pleasure to watch.
uhhh, spring washer. to help with the backlash, yeah that's it. did it on purpose.
Excellent choice, The bronze thrust washers should serve you well it is the best choice for high pressure and slow revolutions.. They will require frequent or constant lubrication. Great engineering!
Nice job! I used to have to make spacers for the electron microscope Wehnelt cylinder that were less the 1mm thick. I had to always make them about 3 mm and then sand them down to thickness. I made a jig for the belt sander to get them parallel to the belt surface and glued them to a stub to sand. I love to see bronze being machined, especially with a sharp tool like that! Thanks.
simple and easy fix. that's why I like your content.
Problem solved, and in a way that makes future wear a trivial thing to fix. I like the plan and how you made it work.
Yep, new washers are easily made in a matter of minutes when needed.
Nice work. Bronze cuts so well.
That's progressing well Adam.
Hi Adam, this is like Christmas morning for me... I just can't wait until you've completed the repairs. I'm so much looking forward to seeing the alterations work and watch the G&E perform without that 'climbing' at the start of a deep cut!
Best of luck buddy, I hope it exceeds your expectations.
That little bit of spring in the washer might even help when adjusting to limit backlash.
I like the idea of Grandson using Granddads Starrett to fix a machine from great grandads time
Nice accomodations for the washers.
I just loved this video Adam, personally I'd have removed a little bit more steel from the leadscrew, so that i could have slightly thicker washers , but the bell in the 20 though one actually helps the process as it puts a preload into the unit, thus as the locknut is snugged up any backlash is totally eliminated. Nice job my son I can hear your dad and grandad saying. And by the way loved seeing you use your Grandad's Starrett special micrometer
Great job Adam - I did wonder if punching out 'washers' from sheet shim material might have done but still - super fix - worth keeping lubed now I reckon.
Yeeeeees... some more Abom79
Nicely done Adam.
What a craftsman.
"like it was made for it" well it was Adam! lol
Hey Adam , just a tip I've never seen you do .
When you have a smaller part that you are cleaning up by hand on a large flat surface when polishing or cleaning up by hand use a figure 8 rubbing pattern and that will keep the part from sanding or polishing by hand from taking material off one side .
The figure 8 pattern will put the same pressure on all edges so you dont make a wedge or off flat part . If that makes sense .
I had some similar fits making 0.023" thick bronze washers. I tried quite a few things before figuring out a recipe that worked.
That recipe for me was a fresh carbide insert in my Kennametal parting tool, with the angled insert having the extended point on the right side (the shape that minimizes the tit on the parted part). Using the power feed set to a brisk pace diving into the part. Oh, and using WD-40 as a cutting fluid seems to help (or maybe it's just something to keep me busy while the feed does all the work).
I could never get flat washers using my HSS parting tool, no matter how I ground it. Also I couldn't get flat washers without the brisk power feed even using the fresh insert in my Kennametal tool. Manually driving the cross slide, or using a comfortably slow power feed just never worked.
Now that I have that recipe, I can churn those washers out by the hundreds.
Very enjoyable video. I always learn something watching your videos. Thanks.
Thank you Sir for the wonderful video, I am looking forward to seeing these, very interesting indeed.
The ten thou one looked like a miniature cymbal!
I have a suggestion.
Before you install the friction wheel over the thin washer, try rubbing it down into the oil groove a few thou. This will let the oil get between the washer and the nut, while still letting the oil get down into the bore.
Might be able to put a piece of 12ga or 14ga copper wire above the washer and tighten the nut up a bit to force it down into the groove. Pretty it will distort the washer, but I also bet it will work just the same.
Instead of trying to part off 10 or 20 thou it might be easier to make yourself a little punch and just punch them from bronze shim stock. Great video as always.
I tried that already and it’s not as simple as you think.
EPIC AWESOME .. Great job Adam.. Smooth and no backlash !
I love the work you do it’s so amazing
Good stuff Adam, Enjoyed!
ATB, Robin
Hey losing a key happened to me 2 weeks ago. I was replacing bearing of a vacuum pump motor. I just set the key aside so I would't lose it. Well I made a new one and ended up finding the other one. Your key will show up too.
Very nice work Adam!
I would have been tempted to clamp the bent thrust washer between two clean blocks of steel and put it in a common kitchen oven at 300 F for an hour. Would have turned the oven off and let it cool to room temperature. This is similar to what they do in tempering steel. I have been able to greatly reduce the stress in 1018 cold rolled using this technique. Maybe it would have flattened that thrust washer.
About that key; I remember you putting such a key in your right back pocket once. Maybe you did that again.
Nice!! Looks like you got a "handle" on things!!...LOL
awesome work Adam
Adam I though I was the only one that put parts in a safe place , were they won’t get lost, only not to be able to find them when I need them!
A nice quickie project video might be to make a tool post shim to make the Victor and the Monarch have the same center height, since you share Multifix tool holders between them.
What might work with parting off the thin washers is to not quite part off before boring (leave a few millimetres or thirty seconds of meat to where the bore would finish), bore and then finish the parting off.
Listening to you talk about dimensions in imperial makes me truely appreciate the metric system,
Ben Whitmore I’m with you on that one Ben. Must be hard working with both, having to buy two of everything. When it comes to repairs more and more are from things made overseas and the rest of the world changed to metric in the 70’s -90’s so theses machines are now getting closer to the repair stage.
Love your stuff Adam 👍🏻
Nice job Adom
You can make a really thin and straight shim by parting of a thicker one then glue it on the end of an arbor or piece of stock and then thin it to final thickness. Give it some heat to get it off and some acetone to clean of the glue.
Looks like you could be making watch gear blanks!! Look out ClickSpring! :P
Love your videos Adam.
You are an artist man.
Good addition to the slide. I'm surprised G&E didn't have something there like what you made, I guess they figured the steel on cast iron would be Ok for the life of the machine.
well it kinda was, it still had adjustment left, its just not the smoothest option
Now that you made a new key you will find the old one..
I have always found the easiest way to find a missing thing, it to replace it with a new one :)
Monarch time = happy time!
An airblast to evacuate the chips might keep them from piling up and bending the thin washer.
It's a 10/1000th brass belleville washer !
Cool vid Adam. Was thinking, could you “reinforce” the super thin washer by supergluing a heavier/thicker washer to the front of the stock you’re parting off? That way it would kinda act like a thicker washer as you parted it off then you could heat it and pop the thin washer off the other piece
Adam nice work.
Looks good, just adjust it as the top washer flattens out and yer golden. :)
Thanks Adam.
I am truly envious, it sucks being without a machine, even a silly Chinese lathe would be better than nothing.
I would be doing the same thing you are doing, on the lookout for a used Chinese lathe locally, sometimes they come up, and often they have some tooling as an extra.
It wouldn't hurt, as most of what I do is for R/C Aircraft, so, everything is tiny.
You should check out This Old Tony. He recently bought an ultra cheapo chinesium lathe, and is running a series on how to improve it. From what he said in the last episode, he is going to make a series on how to make new metal gears for it, using nothing but the lathe itself, and a few hand tools (the *really* cheap Chinese lathes have plastic gears from factory).
Look at Sherline lathes . I have a bigger lathe but if I wanted a wee tiny lathe these would be the people I would buy from.
They make all sorts of stuff.
Just call them to make sure you get everything you need like the gears and attachment for threading.

Love it!
Be sure to put Granddad's caliper back before you lose that! New ones are $400 on ebay.
Catcher tool. NICE. Can't tell you how many times I've dug through the chip tray to find my parted off piece. Why didn't I think of that?
For the thin parts that warp, I found this method from clickspring who makes little tiny gears for clocks. He superglues 1/16" engravers brass to the lathe. He also grinds the cutting tool on both sides. Here is the technique" th-cam.com/video/ZSXDIraHz3k/w-d-xo.html
Could you put a thin shim under one of the toolposts so that the toolholders can be used in either lathe both without changing height?
I'd recommend the TH-cam video Play nextPlay now Machining ultra thin shaft spacers and precision washers - Duration: 18:41.Joe Pieczynski. Keep up the good work.
5:40 "Whoa... off quite a bit."
I'll say! It wobbled so bad you could see it over youtube! 😆
10:16 "Like it was made for it."
lol, it was. You literally just made it for that. 😉
Amazing results. The thin washer is almost invisible in that closeup shot at the end of the video.
I'd put a round on the live center and put some pressure against the part that's trying to roll over. Just a bit to keep it straight.
You would be binding up and rubbing the tools
Glue chuck for thin parts. Bandsaw it out of sheet brass and turn.
Very well done, Could I offer an idea. If the washer needs to be replced in the future for a thinner one I would Part it off thicker than needed, sperglue or shellac the parted piece back to the bar stock, face that off to required thickness then gently heat it up a little so the new washer comes off without a buckle ? I do think that slight spring in the washer may be a good idea.
Hacksaw blades ground to a fine knife edge make better parting tools for thin stock.
Nice fix.
When you are drilling with the tailstock, say at 16:25, what causes the drill to drift? This also illustrates the necessity to ream for correct size.
What you're seeing is caused by the 'web' of the drill trying to cut the material, and having trouble doing it. If he would have drilled a shallow hole with a center drill, that 'walking' would not have happened.
At that size, would it not be simpler to cut the shim out of shim stock? I'm pretty sure shim stock comes in thicknesses up to 2 mm thick.
if you have it :)
Just like it was made for it...
fixed it right up. but I am curious would cool mist or flood coolant kept the brass from warping under the heat of parting it off? (please remember newbie here lol)
how about parting off that washer too thick, superglue it back on and then face to the final thickness?
very common in lathing small pieces. (see "Building Mini-Motors videos)
VERY good and very functional idea.
