probably easier to make some small shims or shim.wouldn't of thought you
could sort the actual arm out.

chop up a bit of coke can or baked bean can and wrap it around the spindle

A peice of tape measure would make a better shim than a coke can .

I had the same problem on a set of maxy cross's

I took it to a company I know who did broaching (cutting square holes) their adivce......................shim it

Becuase of the age of the alloy + its forged alloy + the cost of broaching it would be

You can buy shim steel but to be honest........I had "coke can" shims in em for about 6-8 months and with my 19 stone bouncing on them the were still nice and tight when I sold em

Thanks for everyone else's replys

I was thinking the shim route but didn't know if there were any other ways of doing it
i.e. squaring it up and putting a washer on the front to force it further on the taper $:-\$

so thanks
