Re: Millrite u.s. Burke backlash?

I'm not trying to make your efforts look less than acceptable. I guess you can compare this to an engine rebuild in a car. Some folks consider re-ringing the existing bores, using the old pistons, and installing new bearings, as a rebuild. Others would question the condition of the cylinders as to ...

Re: Millrite u.s. Burke backlash?

Thats cool Harold .. I'm just of the opinion that some rebuilds are more thorough than others. Your definition just seems a little too black and white for me. What if the ways or screws are in good shape and you replace one but not the other, I guess you can't call it a rebuilt. There a million grey...

Re: Millrite u.s. Burke backlash?

Hi There, Make sure your thrust bearings for the table screw are adjusted correctly (so you are not getting "play" from them). Good Luck! -Blue Chips- Webb I am almost done with a complete disassemble/re-assemble of my millrite and am curious what you are calling thrust bearings on the table screw....

Re: tool holder question

lol ... how can you not listen to Harold .. he's like some ancient book. You can't argue with experience like that. Every now and then he gets upset when someone argues about not needing to do it the right way .. he doesn't care if you do it right or not .. just don't say that it doesn't matter .. g...

Re: tool holder question

so ... on the chart pointed to by Steve .. it says that a P nomenclature requires an 11 degree relief. So .. is the relief angle already cut on the insert and the insert sits flat on the holder.
