Quote:"Durathane sounds very interesting. Who makes/sales it? Any websites? I've Googled it but I didn't find anything that matched what you are describing."
Err, uh...there's a good reason for that. Probably due to all the industrial solvent fumes my system has ingested in a younger life, i seem to be making up new product names for some I've used, or at least running a few different ones together.
Went down cellar and pulled the product out, it is Devcon Flexane 80 (castable). It can be modified with additives for duro between about 60 and 80. This is the one I use. To develop a good bond on metal, the metal should be abraded or sandblasted, and primed with the proprietary primer. There are primers for other substrates as well, i believe. Possibly i should be using one for wood, too, but for my handplanes wood/metal app there are no fail/safe consequences.
I started using it about 15 years ago to cast urethane rubber rollers for small 20" import wood planers. Made a set for myself, then a couple buddies wanted them. Then when i started making the hand planes a few years later, it seemed, like "I've got most of a gallon can on hand, why not try it". Since the planes only take a dab or 2, still working out of the same (formerly) gallon. Am always careful to purge the container with argon anytime it is opened. It ain't cheap these days. But handy for certain things like making urethane rubber parts.
They also make a flexane 94, for rigid rubber parts up to, you guessed it, 94 duro.
Sorry about my poor memory for product names!
