Plenum

[Paul Armstrong]

Has anybody else , apart from me put a plenum underneath the block like where the dowty washer goes. I did this years ago and it made my non regulated gun pretty darn consistent

Long, Long time ago....on the other side of the Pond
On the AirgunAdvice.net forum.
Our in-house Rapid Tuner..Swift
He made an Experimental Rapid Mod.... .50cal!!
He needed More Pre-chamber(Plenum) space,
So He made up an elbow and small tube that attached to the rapid where the blanking plug is located..

What kind of barrel did they use.
(16-12.7)/2= 1,6 mm   that would very thin walls in the action block.

Does someone have a picture of this monster

It was Soooo Long ago.....
All the photos were lost when the Photobucket stabbed their users...
They started to charge for their hosting service... but If you want them back they would charge you again!!!
So no photo on this....

But if my fading Memory of this project... Swift Bored out the Receiver!!
To give a little meat to the barrel extension!!

The old AirgunAdvice was a Very Fun PLace..
We had many builders, modders and a few very talented Machinist!!!
But in the end.... the Economy is what shutdown the site!!!
It was during the Mortgage Crisis, everyone sold their Airguns...
The Activity of our site dove off a Cliff!!

Swift was a friend too...
He lived up the hill from about 2 hours away.
He setup Shroud on my Titanium Rapid!!
I lost touch with him a few years ago......
