The updated version does indeed fix the polygon problem I noticed, although
as you pointed out it is not BFC compliant. I agree that each gear-size
should
have appropriate teeth widths, preferably as a primitive. I was noticing
that
they were different sizes just the other day. I would still like to see what
I
could do with this, but I certainly don't want to step on anybody's toes.
Do
you know how I can get in touch with Mark (if he's not checking this
discussion)? His e-mail is not listed in the part and he does not seem to
be
listed in the LUGNet member directory.

Definitely. Thanks.
