Re: toolpath creation problem or wrong interpretor setup?

Hi Tim, Jim,

Yeah, like the 7BA carbon steal tap (from England) I just broke! And I
was being nice to it! I'm milling the cylinder for a Stuart steam
engine. I decided to also mill a "practice" block (CNC comes in handy
for all those holes). It has "more conventional" threading. 5-40?
Right. I probably have a dozen each of the conventional 4-40, 6-32,
8-32 etc. taps, and I THOUGHT I had 5-40 taps and dies. Never found a
single one. Easy enough to pick up, but in a similar error, I also
THOUGHT I had a stockpile of 5-40 allen head cap screws. Oh well.

On the CNC, another thing that could get you in to trouble quick is
drawing the part in one orientation, and needing to have the "setup" in
another orientation. Also, having the drawing origin different then a
convenient point to "touch off" on the work piece.
