Will make this piece even higher, to at least accomodate 3/4" faces w/o having to refit the blank half-way thru the process. Some sort of alternate motor-driven feed will perhaps replace the M4 threaded rod on top, as I already have to use an Arduino to control the cutter speed. Perhaps this'll be a completely automatized "CNC Gear Cutter Mk XX" when I´m done (if ever)?
