- Sup folks!
So it's been a while since I completed my Reverse Change Gear Box. Here's a link if you wanna check it out. • Reverse Feed Gearbox R...
I finally found some suitable material to replace that pesky bushing, Aluminium Bronze! It's yet another learning experience for me and I'm happy to share it with you! 😊
So satisfying! The parting off sequence had me squirming in my seat though. I hate it when you feed the tool and nothing happens. Feed a bit more and it digs in. Usually ends in tears for me.
Regards, Mark Presling
Lol, that's exactly what I was expecting 🤣. I'm getting better at it, hard to know how much pressure is required when parting off different materials. I've been finding a consistent feed rate is best in most situations... most😏. Cheers 😁
Hey Mark.
Looks like that shout out from you did a great job.
It,s well deserved also.
Chris has always had a great channel to watch, just missing some attention, LOL.
thanks for your show and nicely to explain
You are welcome! 😊
Just what I was looking for! Thanks!
You bet! Cheers 😁
Good job with the repair. Cheers
Peter
Thanks, Peter! Cheers 😁
Great job, nice bit of metal as well, expensive but did a nice job. Well done .Regards Mike
Thanks, Mike! It was a treat to work with 😊. Cheers!
Hey Chris.
Seems you have gone from Zero to Hero.
Maybe that shout from Mark Presling got things kicking along.
I feel your channel was great to watch.
It just did not have the following it deserved.
All the best with the growth of views and subs.
Thanks, Peter. Mark has one of my favorite channels, it was pretty awesome to get such a kind mention from him 😊. I only hope I can get a few subs his way when his stickers arrive😁. Cheers!
Great repair . I wonder if it could have been phosphor bronze the way it chipped ? Cheers .
Thanks! Everything just works so much better now. Wish I knew how much difference it would make a year ago lol. I'm learning though 😊.
The guy at the machine shop said it was aluminium bronze, but I really have no idea, first I've ever machined bronze. Kinda felt a little like cast to be honest, of course pretty limited in those regards as well 🤣. Sure sings though 😊. Cheers!
I was wondering if it might not be ally bronze but one of the other varieties such as SAE 660??
Been nice if you could have knurled the old boshing.
Something in mind? 🙂
Mission accomplished, good job.
Thanks, John! Cheers 😁
Interesting, I just ran into this channel.....I just talk to a gentlemen yesterday about making gears for a antique tractor transmission.
Better one bush in the hand instead of 2 bushes in the tree????
That Aluminium bronze is wicked nice for lathing! That finish is very noice!
Keep up the good work!
Thanks! I really enjoyed working with that stuff. Should still have enough material for two bushes in the tree if it comes to that 🤣. Cheers!
Gday, beautiful repair, nice fit and finish, looks very similar to brass the way the chips were, great video, thanks take care Matty
Thanks, Matty! Seems to machine similar to cast actually, with the small, almost dusty chips. It really sings too 😃. Cheers!
Nice one. One day your machine will be better than new.
(it's the ghost pass that made it :-) )
Thanks, Rusty! I'm actually surprised how much difference that made. It shifts so much better now 😊. I'd imagine my surface finishes will improve as well. Gotta love ghosts! Cheers 😁!
Hey man, I got a comment from you in my notifications and it totally disappeared for some reason. I did not want you to think I was ignoring you. Thanks and all the best!
No worries man 😊. Pretty sure that happens to me too from time to time. Cheers!
What would this old tony say about this style
Nice Job there Chris. You'll have new machine when all said done.
Cheer Fred
Thanks, Fred! That gearbox now works better than it ever did lol. Cheers! 😊
Job well done sir, I need a cross feed nut for my pratt&whitney 5/8 8 tpi left hand. The taps are higher than a cat ass in top a pine tree, gotta figure something out.
Great video.
Thanks, man 😊. Yeah, them acme taps (especially the left-hand ones) exact a heavy toll. I was thinking of trying to make one out of drill rod for a 1/2", 10tpi, left and right while I'm at it 😁. One of these days...
Cheers!
Anyone tell you that you sound like AVE ? I just purchased a 12” piece to turn into rings , hope it works !
A few have although we look totally different 🤣.
Nice job. I’ve stippled a lot of axle housing to make sure the race would not spin again.
Thanks! I don't think it will come to that but if it does that sounds like a good solution, thanks! Cheers! 👍😁👍
What feed rate do you use for your power feed? I'm using .0035" feed rate on my atlas but I don't get as nice of a finish as you. Not sure at this point if its my feed rate or my cutting tool.
Hi, Josh! Well my feed rate according to the chart is .0033" per rev. I do however run a fairly large radius on my cutter. Try round it off on a stone and see what happens 😊. There are other odd ball factors I've found that can also make annoying blemishes and tool marks like loose gibs, crap in the lead screw and a big one, sloppy spindle. If that nut in the back ain't just right it can cause all kinds of problems. Hope that helps 😊. Cheers!
Very interesting video. You should quit laughing at your own jokes, they're not funny.
Thanks for the feedback. Believe it or not, I find it annoying too 🤣.
Its hard to gauge how many RPM you're running there on the video, but it looks fast for parting, I like maybe a quarter of appropriate turning RPM's, around 25 ft per minute, and keep your tools nose clearance minimal, maybe 3 degrees. I have pretty good luck like this with a 1917 Hardinge using HSS parting blades, its heavy for a 9 inch lathe, nearly half ton, but its got plenty of wear, so Id say your atlas and my cataract quickchange are in the same ballpark of capability. There is something oddly satisfying using a machine to repair itself, right?
Dam rights it's satisfying 🤣! Think I was probably doin somewhere between 450 and 550 rpm. I haven't actually done the figuring since I swapped that motor pulley. Can't seem to figure this lathe out, doesn't like 1018 that's for sure lol. Everything else seems to part off ok... most of the time 😏. Cheers!
Hit me up on Facebook I have a brand new set of forward and reverse gears for that Atlas. I will be glad to give to you.
Wow! That's extremely generous 😊. I'm quite happy with the ones I made for it but i may hit you up for other parts 🤣. Cheers, and thanks!
Do you by chance happen to know what the dimensions of that bushing were? I'd like to turn one for my own lathe but would rather not have to tear it down first to measure it
Sorry man, looked all over for the original, if you like, check out tha Atlas Craftsman Group on Facebook. Tons of info there 😊
put the bush in a zip lock bag place in freezer... two hours later push it in to place with your fingers !
That would have been the way to go 😏.
Love it when a plan comes together. Most of my work is done "on the fly," and I never think about setting up a camera until the work is nearly done.
A few that do their own foundry work are making their own alubro (my own name for it). Seems the ratios have to be pretty exact to get something that is tough, but not too tough to work. If I ever get a foundry set up, I plan to try it for myself, just to see if I can do it.
That does sound like a plan! It's pretty expensive stuff for the average home gamer, especially when you get into larger diameter material 🙂.
Great video Chris, Like Mark I was squirming a bit during the parting off... I think I would have chickened out and sawed the bugger off.
Lol, I've come to the conclusion that chickening out is one of my biggest problems when parting 🤣. I have had more than a few pucker moments though 😬. Cheers!
If you have a brake cylinder hone you can polish the inside with some oil
I had a fairly large radius on the hss cutter, should be fine with it being a very low speed application. Although, that would probably work very well for getting in that final
.0005" when needed. Thanks 👍😁
Presso sent me. Like it here. I'm staying :)
Nice! Welcome aboard! Cheers 😃
Nice video. Looking forward to whatever else you do.
Thanks! 😁
Love the format of this video. Kinda reminds me of This Old Tony, and thats high praise! Well done.
That is indeed! Thanks, Marty! Cheers 😁
I was just messing with this bit on my Atlas last nite. The ZOMEK is fuggereed and I either got to fabricate or throw money at it.
That's unfortunate 😟. Mine had a pretty nasty crack but managed to patch it up with some of those low temp, zinc/aluminum brazing (soldering) rods. Kinda ugly but the repair seems to be holding up.
@@Just1GuyMetalworks posted some picks on a group. Theres not much left of most of my Zomac. Gonna figure what I can fabricate and price what I cant.
Just brilliant! Need a part make a part baby! Liked and subbed.
Thanks! 😊 Indeed the lathe is one of the few tools that can fix itself lol.
Cheers!
The secret to cutting that stuff is a razor sharp tool. Cutting edge don't last long as that material is kinda gritty and dense. I use carbide but hss is good as long as you keep it sharp. I have made thousands of bushings working for the Boeing company. When you have a long one give it a little more chamfer so it will take the bore easier. It is after the fact now but a little Locktite would have been good on the bushing too. It would be a challenge but you could actually build that whole box if needed. just simple machine work. I am sure you could do it Good job...
Thanks, Johnny! Kinda flattering to have an aerospace machinist watching my channel 😊. It seemed to machine quite nicely. I generally only get the 10% cobalt hss blanks, supposedly a little tougher and they do tend to last quite a while only needing a little touch with a stone from time to time. I have been considering making my own brazed carbide tools. Just a matter of getting set up to grind them. Thanks for the tips! Much appreciated 😁
@@Just1GuyMetalworks or consider making yourself a tangential tool, easy to sharpen and you can use HSS for extra sharpness.
That is nice work. From Tway Saskatchewan.
Thanks! 😊
Awesome! It's always a bit of pucker factor when you're sneaking up on a bearing fit. At least if it's a smidge snug it will burnish the bronze to fit. And isn't it ridiculous what copper/brass/bronze alloys cost right now? Every scrap gets saved here, lol!
Yeah, a solid bronze piece like that would be like $15-$20 per inch! I got lucky with finding that piece of hollow stock. The guy at the shop said it was not a usual piece to have around. Was still like $6 an inch though lol.
Thanks for the videos. I enjoyed them.
Right on! Cheers! 😁
Nice Bush.
Thanks! I'm bushed after that one 😏. Cheers!
Top job mate. On to the next …
Thanks! 😊
Frikken awesome
Thanks! 😊
Excellent job
Thanks, Mike 😊
That was great!
Thanks! 😊
Very nice! I think the first thing I ever turned on a lathe was a bronze bushing for my old hand-crank forge blower and I actually have a project coming up where I'll be attempting to make my own C934 bronze to make up a bushing for an old winch! Bronze is an awesome material :D
Thanks! Definitely was a lot nicer to work with than expected 😊. Cheers!
Nice project. Several months back I got a good sized piece of bronze for odds n ends. Only issue I had was cutting it with my portable bandsaw. Otherwise, seemed to machine very well
Thanks! I tjought it machined really nice too 😁. Cheers!
Couple things ( I’m not “that guy”):
1) it’s better to rough OD and ID to within a comfortable finishing pass first. Some materials will relieve the residual stresses while turning. If you finish OD, or ID , then rough the other to size, sometimes they go out of round. Only important on parts like your plain bearing.
2) you could use your vise to install the bronze bearing if you have enough travel. I’m thinking you didn’t for that reason. However, if the old bearing was really stuck, just use a very short steel press tool to get the thing moving. Once they move, piece of cake.
3) need to keep parting tools very sharp on bronze/brass. Maybe just stone the edge, or regrind if necessary. Once a dull tool digs in to bronze, it gets interesting fast.
Great job, thanks.
Thanks for the advise 😊. I am basically just a beginner in the grand scheme of machining so tips like that are thoroughly welcomed 👍😁. I have actually used my vise like that on a number of occasions, just not enough travel in this instance. As for the parting tool, it did ok, pretty sure the weirdness was coming from the operator 🤣. Once I stopped being a chicken and went for it it parted off nicely. Thanks again for the tips! Cheers 😁
Mark Presling put me on to your channel, You do some nice work, and it's nicely presented. I'll definitely keep watching, some very good tips.
Thanks, David! That's some high praise indeed 😊. Cheers!
When measuring only the unsupported end, you need to beware of deflection in the part or the closer, supported end will be undersize. Also, your parting tool is set too high or needs more back (bottom) relief. Finally, I would polish bearing journals to size with Emory cloth.
Thanks, Byron! Indeed there was some deflection in there. Did a very light pass in the end there, probably could have used a polish for those last 3 tenths 😊. The parting tool was ok, think the weirdness was coming from the operator lol. Once I steadied my feed it parted off nicely. Thanks for the feedback! Cheers! 😁
Jeeze, I'm glad I found your channel, so easy to listen to and great content... I might learn something now. Subbed here!
Well jeeze! I'm glad you did too 😃! Thanks!
Nice job man! The boss man was psyching you out on that aluminum bronze. Thanks for sharing
Ha ha! Possibly 🤣. Thanks for watching 😁, cheers!
noice! Well done Chris , usually on a bush like that I will turn down a little lead so it starts in the bore straight. Enjoyed, cheers!
Thanks, man! Personally not a fan of installing a fancy new bush with a hammer 🤣. Think I see an arbor press build in the near future 😁. Cheers!
Awesome job 👏👏👏👏👏
God bless Stay safe
Thanks, Anthony! Get well soon! Cheers 😊
Mark Presling sent me ... good stuff!
Cool, thanks! Cheers 😊
Sometimes the apparently simple things are the hardest to get right, nicely done. Cheers.
Thanks, Paul! Totally worth the effort though 😁. Cheers!
Really enjoy your videos sir nice fix!!!
Thanks! Cheers 😁
Turned out just right well done.
Thanks man! Cheers 😁
