Re: Syncing of multiple valves.

Connect both valves to a single pilot maybe? The air dumps and both diaphragms open. I've never messed with these, but that's the thought that comes to mind.

Re: Strong boy, (hybrid compressed to muscle)

This thing is just awesome. You have the only semi-auto hybrid and pump action hybrid on earth, that I am aware of. I don't think anyone has ever made either of these principles work before. You've made significant contributions to the hobby and that's rare.

Re: Strong boy, (hybrid compressed to muscle)

This idea is awesome for sure. I had a similar idea for a larger cannon using an acme thread with a turning handle to compress the piston. The only thing I didn't like about the idea was the very long chamber, but with a smaller device like yours, it isn't an issue. Perhaps you may consider incorpor...

Re: Trying to remember a movie plot

I've seen that word "book" before. I think when spoken, it's pronounced "bawk" or "buck" but not sure.

Re: Spud gun exploding

Look at this one this guy made. It's great and super simple. Probably the simplest piston cannon I've seen and works fantastic. He said it can be done without tools, a nd yep, that piston requires no tools. I just watched. This is a great design I think. I suggest the OP check this out and ditch the...

Re: Spud gun exploding

Why not a piston design? They can be done pretty simply and they destroy the sprinkler valve cannons, don't they?

Re: Spud gun exploding

I'm with JSR on this one. The recoil appears to be the main culprit from where I stand. I'd expect that little elbow to break if it's absorbing the recoil from a barrel full of water. I'd use a larger elbow and support the barrel so that it can't move up or down, nor back and forth.

Re: Short question topic

hahaha, alright. I always feel bad when I do that and my ideas turn into a pipe dream :oops: Pipe dreams have a tendency to become reality at some point down the line in this hobby. I started thinking about my last project like 6 or 8 years ago or something and just recently did it. Do some sketche...

Re: Short question topic

You should be able to add as many layers of foil as it takes to hold a wide range of pressures. What are the dimensions of that thing? Also, I wouldn't want to mess with 8 screws every time I wanted to shoot the cannon. Can you use a cam-lock instead? What mixtures you going to run?

Re: Planning the new hybrid

The automated fueling is what I meant. I saw you had to load each pellet. The automated fueling is impressive as hell. Your concept and ideas are innovative to this hobby. I don't recall ever seeing something like this work before. I've seen semi-automatic pneumatic cannons, but hybrid fueling is wa...

Re: Pressure testing hydro

Yep. Do the honey method, my friend. Screw all that complicated stuff. Plumb some high pressure honey into that sucker and wash it off your lawn in 2 minutes = job done. Also, I've heard it said you can reverse the cup seal inside the grease gun so it will seal with water. I tried that on a small, c...

Re: Pressure testing hydro

OK, some thoughts here.... 1 - Actually you *can* fill it with water and then pressurize with air but you absolutely have to do this one dead nuts correctly or things can go badly. Most folks haven't the know how or equipment to do it right and there are other techniques that are easy to do so unle...

Re: Pressure testing hydro

You can't fill with water and then pressurize it with air. If it fails it will explode. You have to fill it with water and then pressurize it with more water or grease from a grease gun. I'd suggest getting a nice large grease gun and modifying the seal inside so you can fill it with water and use i...
