A friend has made a mold for me and I have now made a few prototype 1.75 inch gaskets that fit the Columbia floating reproducer. They are blue green in color. I tried one in the reproducer I had apart for a rebuild and it seems to fit great. The rebuilt reproducer sealed nicely and sounds good. Now, two questions. a) does anyone else want to try the prototype? I'll send them one for $2.00, post paid. b) does anyone know the Shore hardness value for the original latex gaskets? If I'm going to cast these in (hopefully) black, I want to get a material that is as close as possible to the original hardness.
Thanks, Ron L
