I needed to cut a slit on the end of a pair of screws but I do not have a slitting saw so I improvised.
I clamped a hacksaw blade in a tool holder

I set it on the centre and by applying pressure with the saddle and drawing the cross slide back and forth I started the slit

It wasnt fast but it gave a good even saw cut

That I could finish by hand in the vice with the hack saw with no slipping or marring of the head.
It worked
Charles? When are you gonna just guy a gosh darn mill?!
As the old saying goes, necessity is the mother of invention. Great workaround, Charles!
I have a mill and a slitting saw, but when I just want to slot the head of a screw and sometimes even a fussy one that needs to be pretty. I use this collet block that I made. I made it for other needs but while I was at it, I put two holes in it for guide pins. Now I can easily slot a screw head. Centering is controlled. Depth of slot is watching the blade. Works great!
