I went through a repeat of the lathe threading routine on the Craftsman -- a lot easier with the lathe already set up, and the earlier experience under my belt. I was able to use the old tap, as well to do the final thread sizing. Since the tap is made of the same screw material I will be using, the clearance is very close, with almost no backlash. It was also at about this time that I figured out that the slightly eccentric and relatively close relief bore was probably the cause of my earlier problems. Of course since this insert wasn't in the ram, the tap couldn't jam. And the threading was easily accomplished. |

And finally a trial fit -- it does seem to be a slight interference fit. I didn't drive it home, because I want to clear out the relief bore -- no sense having the jack screw binding. I guess I'll have to make up a longer boring bar to do it. Might take a while because of springing, but at least this part of the process will be finished. |

Persistence pays off, well done Steve :thumbup: |

Good Job. Pretty confident that the insert works out better than the original plan! Pekka |
