Yesterday I broke the head off the M3 grub screw on my pinion.
The tiny Alan key hole had been stripping out for some time - partly because I needed to overcome the locktite to get it out.
I can’t remember if it was b264 or venom who suggested just drilling them out and using M4 or M5 instead - but it’s good advice - I went to a friends who has a drill press and he helped me do that.
Works like a charm.
