Welding Rod,
Brilliant! And your creative build has another application ... Metal Punching.
Let me elaborate. When metal punching numbers on a hobby part
one must hold carefully the punch on the metal as perpendicular
as possible, hit the top with a hammer, and keep from flinching
as hammer sometimes slips.

I have a 1 ton press and do not want to spend its purchase cost on a ram
with a cut-out to hold a 3/8th punch. Your clever presentation will
now be used to hold the punch firmly and perpendicular, apply pressure
with the handle, and a thumping the top of the ram with a brass
hammer transferring all the force in the Z-axis to the part being marked.
Thank you for letting us see this. It certainly has been gratefully received.
Best!
