Couldn't wait. The three nylon locating pins are in. .006 oversized and pressed in.

It'll almost be a shame to have to knock them out, later.

Interesting - will nylon pins really hold those two plates together securely through the rest of the machining? I would not have guessed that... but that's all it would have been is a guess. I'm curious, is there any rule of thumb you used to know it will work, or is it just based on experience? Thanks.

It is based on past practice. If it were just one or two it would probably fail at the worst possible time. Being three points I have complete faith in it. I don't like to bolt parts together like a lot of machinists do. Also the three hole will be for something else later. It's one of those things that I do and have done that works for me. Hope this answers your question?

2.253 and done. Just shape it now and these parts are complete. Yes, that's a flycutter. They make great boring tools also. I reset for the next cut with a Dial Indicator. I cut .100 at a time. The nylon plug locators are rock solid as always.

Looking good as always man. What kinda mill do you use?

I have a Clausing 8520.

Just the lock screws and these are done. They are a nice slip fit.
