From this point forward, if I invest in drums and/or rotors again, they will routinely be sent off to Cool Rotors for cryogenic tempering. I'm liking the result so far.
Have you seen the FiberFix ad where they roll the Metro down the 140ft cliff? I'm thinking I could use long-fiber body filler and wrap that with hemp tape for the joins. I have tab-and-slot scheme for inlaying the composite panel in the tube frame. The top panel might be redwood strips covered in fabric like an old woody.
You mention 'hour-glass opening' just after 'abating foam'. It will be interesting to see what turns up.
