I looked at what it might take to make a D-hole punch.? Seems that a 1/2 inch
Grade-8 bolt could be turned to the desired diameter and one side ground flat
to make the D part.? Then turn the end down further and thread it to serve as
the puller threaded part.? The socket end could be drilled smaller than the
D-section of the punch and filed to size and shape, with a thru-hole for the
threaded part of the puller.

Not really a machinist here, but little metal projects do intrigue me.

Arv,

I've considered making my own. I have a drill press and an arbor press. I've got a good set of greenlee hole punches (the bolt driven punches) but none that are d hole or that small (I think my smallest is 1/2"). I believe greenlee does make d hole punches.

I wonder if Marshal had these fabricated.?

Thanks
