I am making a few parts that require being turned around, faced and center drilled on the end that was parted. Sizes range all of the way up to 1.525" O.D.
While contemplating how I could get this done reliably on the SLP, I have been using my manual lathe to make a holding fixture and facing the parts as needed. This brings up the problem that each size change requires a new fixture to be made to insure concentricity.
Emergency collet? A few regular collets with a plug clamped inside and machined out to fit the sizes I need? Repeatability of either option?
If I didn't have to baby sit this machine, I think I would be just fine with how I'm doing it now other than having to make a new fixture after each size change. I could be facing and drilling while it was making a new part, but I can't be doing that. Something I could use to hold the parts in the SLP after making the short run would be faster than how I am doing it now.
Suggestions?
Edit: Something I should have probably checked before hand. The O.D. of most 5C collets are only 1.48" and that would be good enough for 60% of the work involved. Eh, not bad.
Something to hold up to the needed size would be awesome.
