Good show, Bob...........there is a real need for replacement canopies in the US. Thermo Tec was a good source in the past, but they're out of business.
Ray used a shaker-table that lowered a heated acrylic sheet over a felt covered mold. Fascinating to watch, too bad that business equipment, molds and knowledge couldn't be used. Have you tried to contact them?
Wishing you well,
JJ
