Hi, Even though the sharp range is 30 + Years old, They still attract a lot of intrest , & I would also guess the most efficient exhaust ( Total loss ) valve ever ?
But you just know that the plastic parts are going to bite you in the butt in future years !
Thats why I made the Innova Frontend , Silencer adapter & Breech in Aluminium & Brass
I also have a Modded Ace/Innova compression cylinder that works very well the the hyped up pressure ! I have a Pic but can,t find it !!!!
It has an enlarged ( 5 mm ) O ringed exhaust valve,
I,ll find it soon, Thanks for the replies,
I would like to add,
The shortened cylinder works because of the longer stroke, The shortest I have made is by 20mm, The increased pressure is a bonus , But extra Stroke length
is the key here,
We all know that Pressure/Volume are critical to output allied to barrel length
But on a " Pumper " That balance is critical to Input- Output variance .
I made most of these a few years ago, But your views are much appreciated .
I have another Idea, I know it works but have not made one yet ????
