I have the equipment, most of the experience, but not when it comes to hitting and exact bore size this small.
I want to make a .463 star lube sizer
How do I get the ID to work out right.
Turning the od to size is no problem, I want to finish the id to the same quality that my lathe smith dies are.
I doubt reaming is accurate enough and I have toyed with the idea of making a id tool post grinder for my bench lathe..... b7t I don't want grinder dust destroying the ways.
Could anyone recommend a solution please?
