Re: Bridgeport Series 1 conversion and othe r stuff

Chuck, I had NMTB-40 on my bridgeport seriesII and found an adapter
to R8 at ENCO. (www.use-enco.com) I also got a set of NMTB-40 holders
from enco, so they may have NMTB-30.?. also surf ebay, every now and
then you can find tool holders there. I found DA-400 collets every
now and then.
