securing 6 MT sleeve in headstock - how hard to tap?
2021-11-26u2002·u2002I made a 5C adapter for my current lathe, starting with a commercial 6 x 4 MT sleeve. I very gently tapped the sleeve into place, then machined/ground the sleeve into an adapter. Checking the run out its 10x+ more than I want it to be (now .005 in.). If I lightly tap the adapter with my lead hammer the run out is reduced to .002.Get Price
