Hi guys;

Ok, then, here's a question: I've been told that R8 is the taper one usually
wants to go for if given any choice in the matter, and that you can't go far
wrong doing something Bridgeport compatable, when it comes to availability of
parts and pieces, etc. Assuming I have a reasonably strong Z axis to hang it
all on, what would be needed to make everything from there out to the tooling,
be Bridgeport/R8 compatable, including stuff like right angle heads for slitting
saws, etc.?
