Just in case you didn't know the adjustable angle Bridgeport Quill Master fits the Tormach 1100 giving you multiangle milling capacity.
The heavier 90 degree attachment doesn't fit but the Quill Master attachments do. They're cheap right now on Ebay.
The problem has always been collets but they're easy to make. If any body wants I can repost the G-code to do so.
FYI I tried this to find an easier way to mill extractor slots on the ends of barrels.
