HALP!!!! So I finally got it completely assembled. I went to test it and it didn't work
the sprinkler would go off, but the valve wouldn't move. At first I thought it was because the hole in my bumper was restricting the airflow, so I made it bigger. I tried to fire it again and it didn't work, and the piston seemed to be "seized up" because it was not separating from the sealing face even after there was no pressure in the gun, So I had to take my ramrod and physically separate it from the sealing face. So I took it apart again and and examined the piston. I decided to put some silicone lubricant (used to lube paintball guns internals) and lathered on the piston. I then proceeded to go test it again, and IT WORKED!!!!!
So I grabbed my brother and a video camera and we went to test it in the backyard, we forgot to tape the first shot due to excitement (see picture) but remembered to tape the second. (see video)
Anyways I've shot it about 10-20 times thus far but murphy and his laws have struck again..... I've been shooting it at 60-80 psi, and it's worked wonderfully, but when I tried to fire it at 100 psi, the sprinkler went off as usual, however piston seized up again. So I've taken it apart and took picture of the parts. the piston is still quite slippery and nothing seems to have changed, except that there is a depression one the pistons rubber face. Any suggestions would be very much appreciated. At this point I'm rather frustrated.
what the first shot did. 60psi
Second Shot (sorry don't know how to embed)
What the second shot did to the nerf
Piston all lubed up, post being "fixed"
Piston in valve (still not working)
