I pumped it to 40PSI and crammed a frozen spud down the barrel, I was aiming for a palm tree 30m away and hit it first shot, so I guess the accuracy is good. I thought the potato had been obliterated but when I looked around I found a potato sized hole in the fence, on the other side of the fence there was a dent in next doors shed! The potato ricocheted about 3m and still plowed through a fence made of hardiflex!!! And better yet the hole it left is the shape of Australia!! Next I shot a spud straight into the air, it didn't come down for probably 10 seconds, I lost track of it at one stage, which had me running out the front to make sure it didn't hit my car.
The only problem with it is that after every shot the diaphragm gets stuck in the up position, could this be because the thread of the pipe tap is poking through a little bit and causing it to get stuck on an angle, if you know what I mean. Or do you think some grease on the guide pin would help?
On Thursday I'll be satisfied all the cement has completely cured, and I'll pump it to 80PSI then I'm gunna do a video on youtube.
Heres a list of things I'm planning to shoot at:
A large porcelain cat I found
An old internal door
Ply wood
Watermelon
Glass bottles
