My "new" American Tool Works Lathe

What do you do when you tear the teeth off a gear? Why, weld new ones on of course! :eek:

Lest anyone not get my sarcasm up there, this is the PO's work, NOT mine!!!

Don't feel to bad I bought one and paid way to much, but didn't care because I wanted it. The gear can be salvaged. There is better ways to repair it though. Here is one I fixed, sorry for the bad pictures

Had to end my post a little sooner then I wanted, I had a wrecker call, but here is what I would do (but remember I can't see any machines go to scrap) buy a gear blank with the same DP (diametral pitch) and close face width then machine your old teeth off and press fit the new gear on. In my shop I try not to spend money so I would set it up in my indexer and machine slots like the gear above and make new teeth then braze them in. I don't see your little setback as a problem and damn sure not one to beat yourself up over. Look at all of that area on that part to chuck to you should have it fixed by 5 pm today!! Jonathan
 
That looks good Jonathan, nice work!
Problem I have, it's not just the one gear out of the QC that's damaged, I think they all are. In fact you can see some of them in the background of the above pictures. So if repairing them is the solution, it's going to take a lot of patience and time.

Nice fix Jonathan.

MrFixIt; yep patience and time. But just think of the amazing machine you'll have in the end. You may decide to flat-out replace some gears if there are too many missing teeth.
Best of luck with your project!

Spent a lot of time the past few days clearing out a corner of the garage, getting the lathe off the trailer, into the garage on some moving dollies, moved to its corner, then off the dollies and leveled out.
Whew, I think it's going to stay there for the next 100 years.
Still have to rearrange the garage and find a place for everything that's been displaced, but at least the ATW is at home.
That corner is a bit dark, time to add an extra light fixture.
 
Well, the more I get into this, the more I find out I did not know what I was getting into.
Since it's driving off the back gear my maximum speed is not very maximum. My speeds are slow, slower, slowest, and reverse.
The tool post won't hold the holder tight for a darn, it walks over when the tool contacts the work. This may be related to the damaged and repaired T slot in the compound. Although the repair does look decent. Still looking into that right now.
The only way to get the tool close to the chuck is via holder position, the guy that build the drive didn't take carriage travel into consideration; the carriage hits a drive pulley on the far left where there should be another inch or two of travel.
I pulled a bearing cap off of the spindle, someone had used a dremel or something similar to make oil passages in the insert, and left the burrs on the ends. There are little chunks of metal from these burrs stuck in the insert that I can pull off with my thumbnail. Spindle shaft still looks good though. One of the bosses for the cap bolts is broken, one of the four bolts was replaced with a bolt with a shoulder so when it was tightened it took out the side of the boss. Fortunately most if not all of the threaded area is fine so it still does its job.
Well, I'm stuck with it, I'll make the best of it.
