Suppose I have square solid alum bar, with an accurate square collar that
slides along the bar.
Suppose I drill a 3/16" hole clear thru both, for a pin. The pin will now
be in pure shear at two points.
How would I estimate/calculate the load rating of the pin? What type of
steel would be best? I'd prefer SS. Seems to me like hardened dowels-type
mat'l would be near-indestructible. The pins will be threaded at one end,
for a handle of sorts. I would like not to have to harden the pin after
machining, but if nec, I will.
Would anyone KNOW the shear capacity of such a pin in various materials?
If worse comes to worse, I could try to determine this empirically, with
some kind of hydraulic setup/gauge. Or just load the collar with heavy
plates?! Hints on this would be useful, as well.
