I don't see how it'll help as most chain-fires can be traced to the nipples & caps not fitting correctly?
I also can't see the greased felt surviving the first firing.
Great idea, but I think the concept is flawed as the greased wad in the cylinder & correctly-fitted nipples do the job better & easier.

Don't feel too bad. Sam Colt carved prototypes out of wood as well.:cheers:
