I'm thinking you're still not getting it.

The shim goes in the hole before the arm is installed, not after. The only force is from the bolt.

Quoting an earlier post of mine again: "Using stainless stock from a feeler gauge, I'm sure that one could get one or two sizes to fit even cold just by introducing a slight bevel to the square hole..."

With a bevel at the hole's entry, surely the bolt could generate quite a bit of interference fit of the arm on the spindle, equivalent to what is generated on a tapered spindle.
