Thats my problem, it will take time to apply the jbweld, then get it mounted and some 0-80 screws adjusted to get good quadrature. I've shaved the end of the pocket down to a fast 1/16 thick, and was fighting to get a 1 or 1.5mm er16 collect to hold the drill to bore the pilot holes for the tap, dropped the drill, saw it roll into one of the bed slots, and it just vanished, can't be found. So I've got to find another drill of a similar size, and see if I can get it to run true in a collet that small. I have no chucks that will hold a drill that small. So, based on a msg from TomP I found the rt-kernel in the tgz had a bogus as a $3 bill sha512sum. So I've been most of the day fixing that, so be sure and get the new kernel-rt.tgz from my site again. And re-read the README for the ugly news at the bottom. > work.
