Awl --
Specific Q:
Would a plate full of 1/2-13 holes AND t-slots be redundant?
I would like to go all-holes, but I do see some instances where a t-slot comes in handy, like when mounting a tailstock for the 4th axis, where you just want shit "a little tighter". Also, you gotta hope that all the mounting holes for vises et al can accommodate 1" increments.
Opinions?
