I lost a wear strip on the packing line and need to make a new one. its a
piece of UHMW 1/8" x 3/4" x 24". On one end it goes from 1/8" to 0" thick
over a 2" length, or wedge shaped.

I'm sittin' here trying to figure how to clamp this in the mill to machine
it with no good ideas so far. Any suggestions? Should i use the end or side
of an end mill to cut it?

Lots of good suggestions posted already. You can also do nice work on
this
material with a router and some fixturing. If you end up wanting to
mill the
part for some reason, I would suggest a straight-flute carbide router
bit rather than a
standard end mill, and use the end of the bit, not the side. Much less
tendency
to lift the material.
If I were doing just a couple of pieces, I would try the belt sander
as well, with a
back-up block of wood. Watch the heat, though, UHMW has a fairly low
melting
point, and a worn belt (or too fine a grit) will smear it in a hurry.
