REFLECTOR: Roll Trim Spring

[Dennis Martin]

I used two small washers, drilled them and used a couple of tiny nuts/bolts
to attach it to the belt. Tiny bolts run through the belt, then they are
compressed to make a very tight grip on the belt. The spring simply hooks
into the washer. I drilled a hole in the edge of the washers to attach the
springs. I have about ten feet of the belt left over if anyone wants to try
it. Just send me a self-addressed envelope with a buck for postage.

Best,
Dennis
