Not sure who remembers this but, it's gone through ALOT of changes and upgrades.
I was a complete noob at the time I built this, so there have been some things I've upgraded and some that I changed...
So I guess I'll make a list:
Increased porting
Fixed sealing leak
Shortened stand
Reduced pilot volume
Wrapped pilot over to top (for compact-ness)
New secondary pilot
New gauge
Muzzle brake
Took off back piece on stand (changed from I to T)
Lots of new ammo.
Lots of perforated plywood.
So on to specs:
6' x 4" chamber
10'x 2" barrel (partially removeable (for storage))
SP valve pilot
(anything else?)
Now pics!!!
Whole thing on stand...
Pilot area...
Settin up to use "knocker" round...
(In this shot, it went through 4 sheets, bounced off the pile of mulch and flew around 150' into my neighbors yard...
Now the uncommon parts...
This is the piston. It has a 4" diamond blade at the front and the soft side of velcro to help seal. Where's the rubber you ask?
Here it is!!! It used to be a 2" union. It is also used as the barrel spacer...
By this next week, I'll have pics of all the ammo I have.
And hopefully some vids, maybe some high speed...
*Quick Update*
This is a pic of the back two boards in that set of four above.
This is the only pic I can find right now.
I'll have more this weekend (in high quality), and videos.
