The plexiglass piston from SgtMike just arrived. It is certainly a smooth operator. It is a bit smaller overall than the Aune O-Ring model I pictured above, but the piston shaft is quite a bit larger. It has double O-rings and the rebound is so smooth the piston nearly returns to its starting position after striking. I can see a cloudy atmosphere form in the chamber upon compression...driving off moisture I think from the fungus. I have yet to strike this in the dark, but will do so later on today to see the ignition.

A nicely made piston...not quite as stylish as the Cocobolo models but highly functional and fun it its own way.

I am not certain of the maker of this one, but maybe Mike can fill us in. I am thinking it was Steve Leung, but this may not be correct.

Thanks Mike.
