Rubber Stripper

I have Ray Harlan's stripper and found it quite useful in cutting
rubber motors to custom widths. With a little practice, you can cut
rubber such as one quarter inch width to a desired witdth plus or minus
about one or two thousandths of an inch. It is, of course, not easy to
reliably measure the width of an elastic compressible material with a
thickness gauge. But you can make pretty consistent and reliable width
measurements if you practice a bit so that the calipers do not pinch
down on the rubber.

Anyway, sometimes the thickenss of the rubber (as opposed to the width)
seems to vary so that I have to tear apart the two cut sections after
they have been ejected from the pinch rollers. I recently cut a batch
of cutsom width rubber and this happened for about thirty percent of
the length I cut. It was fairly easty to tear apart the two scored
segments. I am concerened that maybe there will be jagged edges where I
had to tear the segments apart and that this may lead to premature
motor breakage at high winds.

Has anyone had any experience with this? I plan to look at the torn
edges with a microscope to assess the situation. Maybe I need to
sharpen the blades but my stipper has not been used very much and most
of the time it makes a nice clean cut. I have a lot of rubber to
experiment with. Some batches are better than others and I don't want
to waste the good stuff.
