Wow! It looks great, Woodsy. Thanks for posting the picture.

does that mean you don't have the diffuser tube inside the rolled screen?

It didn’t come with the tube or screen, just coarse stainless wool. I throw it away and put fresh in when I clean. It’s the same stuff Scotch-Brite stainless scrubbing pads are made from. Costs about $1.50 each time.

... the factory 'shortie' was nothing more than a short, 1" or so long forward expansion chamber tube that fitted over the front part of the alloy foresight block band in place of the longer standard forward section. 3x shortened rods replaced the standard rods and the standard end cap fitted into the short forward expansion chamber. Locked in place by the notoriously fickle hex recessed locking nuts.

In short, the standard gun did away with the forward expansion or plenum chamber. Not a good move as the plenum chamber acted as a vehicle for another well thought out design to operate properly.

Thanks Peter.

Does the end cap need the standard-length plenum to work correctly?

The spiral diffuser is very interesting to me. Do you know how the gas flows through it? I am guessing there’s an interaction between gas flowing through the spiral and gas entering through the center hole?

I am also guessing the spiral creates some kind of vortex in the forward expansion chamber?
