On more than one occasion, I have accidentally screwed my tailstock quill out too far. One time, I did this with such enviable grace and aplomb that I had to either make or buy a new tailstock lead screw, and a new tailstock quill. Before you become too in awe of my awesome machining skills, I'll go ahead and admit that I bought the parts from Grizzly.
While working in the shop just now, even though I'm fully aware of the problem, and this issue has already cost me a lot of Abraham Lincolns for parts, I went and screwed the damn thing out too far AGAIN.
It's obvious that I'm not going to stop doing that, so I need to do something about this quill screwing out. Surely I am not the only moron with one of these lathes who keeps doing this. I'm writing in the hope that someone already fixed this, and their fix worked really well, and they are super proud of their ingenuity and stuff.
The heart of the issue is the way they milled this slot from the end. If they had plunged the endmill in and machined it like a keyway, this would be a non-issue. I know the world class machinists at Shang Dao Machine Making Corporate Company can doing make keyway, because my machine are have many keyway make in that honorable fashion. This quill no am make like keyway, and that creating is problem.
The bits drawn in red are how it should have been made. I just stood there and looked at the part for a few minutes, and I'm not really thrilled with any of the ideas I've had for putting some material there. I could tap and drill for a set screw. I could try hitting it with the wire welder to put a good blob or two at the end of this slot. Maybe I could build up something with brazing rod, and machine it into shape. I guess I could totally go cheap cheap and just stick a blob of JB Weld right there. I might do that, actually. JB Weld solves a lot of stupid problems, doesn't it?
Well, I'll drop this off for the Peanut Gallery while I go try not to butcher my third and final attempt at making a 29-tooth gear. I ain't wasting no more perfectly good alumniums on this demonstration practice project, so either way I go, I am done.
