Well , when I used the same material as the writer ... I was successful .
Testing to happen as soon as I can get a #6-32 shcs to hold the insert . The
article I got the plans from is on page 66 of HSM issue from may/june 2003 .
I made a couple of minor changes , made it a 7/8 mill with a 3/4 straight
shank . I did use a piece of crs I had , as did the author . This time , I
left the piece right where it was drilled , chucked the tap in the mill's
drill chuck . Sprayed liberally with penetrating oil while tapping , I was
still afraid of breaking the tap - and I drilled it .006 big too ...

Guess I should clarify - I turned the chuck by hand , with the mill in
high gear . I wouldn't dare drive that size under power , after reading the
info I got here !

So you made your own insertable endmill? Good deal. Are you able to post pictures?

Yup , and last night after I posted , I found a screw and tested it (still
need to get some allens , slotted head is way too soft) . Works pretty good
.... I can take a few photos and post them in the dropbox , might take a day
or so . Might be trying some insert tooling for the lathe since this worked
out as well as it did .
