seen the future? I have indeed John, and continue to do so ;-)
now the way I make slotted grub screws is this;
make a hex 'nut' about twice as long as your required grub screw.
cut a guide slot in one end (corner to corner, as you say)
now run a bit of all-thread into the hole far enough to make the screw.
Insert a headed screw from the bottom and lock it in place.
cut off the all-thread & file/turn flush with the top of the 'nut'.
Cut the slot, using the guide, with a junior hacksaw. Clean up with a
slotting file if needed.
slacken lock screw, remove grubscrew via your nice new slot.
