Arbor press pin holder
« on: July 26, 2021, 11:21:09 PM »
Quicky project: arbor press pin holder!
I saw someone's arbor press with a drill chuck stuck to the side with a magnet, for holding pins...
I have a tiny press, so I hunted down this hilarious Zinc alloy chuck for $12.39 on Amazon...  actually well made!
I removed the draggy wave washers, turned a disc to fit where they were, superglue on magnets, and voila!  Pin holder!

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. :D

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!

I have a couple of alpha-numeric stamp sets with short dies that you assemble into a holder like the old John Bull printing sets and are supposed to tap with a hammer.

I find gently holding them under my hydraulic press and bringing the ram down slowly (it only goes slowly!) and applying about 1/4 ton gives a very good image in sheet steel and up to a ton for more solid things. It is quite possible to make the imprint too deep if you don't control it  (it's a 60 to press  :clap:)
