Try measuring the thread on the defective one. I
am pretty sure it should
be 6-32 UNC if it's the original part. If it is that thread, then the
problem is elsewhere.
It's a completely different part. The HP one has a hex nut head, this
one has a knurled round head, a smaller diameter screw thread and is
much shorter. I've bodged it for now -- by stretching a piece of
model aircraft fuel
hose over the HP hub. It works... mostly. The wheel is now a little
oversize, and there obviously isn't a taper. I might try attacking it
with the lathe tomorrow night...
Trying to machine eleastomers at normal temperarture with a tool groudn
for mtal turning will produce an awful finish (if it does anythign useful
at all). Probably worth you trying it so you see what happens, though.
