As I mentioned earlier, the crank on my newly acquired DS was broken. I started looking for a new crank and found that nearly all of them had a 14.5 mm opening and the shaft on the DS was about 12mm. No big deal for function but a huge no no in my own mind. So I started developing a way out of my perceived dilemma. A bushing was the only sensible method and metal would have been a real pain but my saw dust pile was getting low so I grabbed a hunk of whit oak and drilled a 1/2" hole just slightly open as the picture shows then I hand penciled a mark just a pencil width away from the hole - notice the subtle end cap - necessary for stability when sanding
then used the band saw to cut that out
then sanded the outside to fit within the crank handle. then inserted in the crank and installed on the Drum Sander - tightened the set screw. case closed, mind at ease
Interesting idea. If that doesn't workout, you could try to make the crank arm out of wood with a hole small enough to press fit and add a set screw. You could reuse the handle from that crank.

I can't see how a failure can occur. It's almost a press fit to the shaft and the set screw pulls it even tighter. It was touch and go sanding it down on the belt sander tho - fingernails got really close several times lol
Just to add, fingernails always loose against a belt sander. DAMHIKT
I have found that wooden clamps, and those router table holdem thingies are your friend, and make great substitute fingernails. I can attest I hardly feel a thing when they start screaming. :-)))))
Sounds kinda like you may have already figured that our though.
