I don’t use the Taig, but I do use the Sherline micro-mill, and
would be happy to advise you on tooling. There is an on line dealer
for Taig named Nick Carter, and there is a Taig e-mail group you can
join, as well as a Sherline group.
You can get a lot of by searching through the Sherline
web site. www.Sherline.com They fully explain their tools and
tooling. You might also purchase the book on TableTop Machining by
Joe Martin (again, Sherline site), as it has lots of good info.
For CNC, there are several e-mail lists dealing with it, but as i
don’t use it, I can’t help you there.
