Licking my Wounds Lathe Rebuild Project

[BillyT]

This is my first post, so my introduction too I guess. lol

my name is Billy and I live in Saskatchewan Canada. I'm a retired woodshop / small engine teacher and fairly new into metalworking.

I am ashamed to admit that I was a sucker when I bought my lathe but i'm sure i'm not the first guy.

Rather than type the story I thought I would just film it.

please feel free to comment on my videos. I will continue to upload videos of this project as I go.

Nice looking Lathe you've got there Billy. I've not seen inside a quality lathe gearbox before so surprised to see the inside was painted! Good idea of course and nice to see. Good luck with the reconditioning.

What about this one back on the 21st?

By the way, looks like you're doing an excellent job on the rebuild as well as the documentation.

Amazing process that Electronic Discharge Machining, isn't it.

Keep us informed of your progress that Lagun is a very good machine
and yours is a decent size too.

That looks like quite a project Billy. The good thing about a project like that is that when it's done, you'll know the machine inside and out.

I'm not sure why the fellow who repaired the gears used EDM. It seems he could have skipped a step and machined the gear teeth directly rather than make an electrode and then use that to machine them, unless he hardened the teeth after they were welded.

Thanks for posting the videos.

Tom, I wondered about EDMing too but maybe the welding was with some kinda rod or filler that produces a hardness that conventional machining wouldn't handle?

[kenne]

Probably the rod was "Hard-facing rod " ,we use it for blades on loaders , tractors , backhoe's,etc. It is several times as hard as 70 or 60 series rod , but difficult to machine as well .

By the way just for the record, he would have used a 'graphite' electrode - not 'carbon fibre' as per the video commentary. I tend to use copper for my EDM electrodes as it makes less mess when machining albeit a more expensive material.

Nice work Billy. It looks like that will be a real nice lathe once you get it sorted out. The spindle through hole looks nice and big which is always a good thing.

I helped a mate pull the gears on his 7" lathe and we had to do a similar thing in stripping out all the gears to get the the seal that was leaking! We made the call to replace all the bearings at the same time.

Thank you for that correction, I was not sure about that.

I agree it's better to change them all now rather than take it all apart again
