PS: I did get it done, but I nuked the gcode from counterbore.py, and used the code from arcgenm18.py, which once I had reinitialized lcnc, Just Worked. So those counterbores are done. But before I dismount that part from the table, I believe I need to find 2 more 5x30mm cap screws and put 5 around the edge instead of 3. This is a 1" thick slab of alu, milled in a circle which exposes the tilt of the head degrees scales, with a flat corresponding to the front of the bs-1, has a cutout for the bs-1 worm bearing and which currently is drilled with a 4.3mm drill so it can be located of the side of the bs-1, and superglued in place long enough to use it to drill the holes in the bs-1 at a size suitable for tapping a 5mm bolt. Then it will get knocked off, those 4.3mm holes opened up to clear the 5mm bolt. All this to function as a flat place to bolt down a pair of half circle motor mounts, far enough out to make a shaft coupling to tie the motors output worm to the bs-1's input worm. All mounted solidly enough I could pick up the whole almost 90kg of this thing by a choker strap around the motor. If I had to. With a jerky electric hoist. Generally I handle it with the hoist with a 16" piece of 1/2" A2 thru the bore, and an orange binder strap tangled around it. Looks a bit dicey, but gets the job done.
