Mostly done with my 10 foot, piston valve golfball cannon.

I've taken these 5mp pics with my phone, uploaded my them to photobucket with my phone and I'm actually posting this whole thing using my phone! I have the Motorola Droid and yes, it does that.

Image

There it is, on my desk at the moment, now, it's not done, it still needs to have the pushbutton 3-way trigger installed into the barrel support, I've built a shoulder brace which attaches to the back of the piston valve, protects the QEV, which also isn't installed yet. It needs paint, among other things. Including a spring-loaded clip holding golfballs which attaches to the feed port, feeding a golfball each time you actuate the lever, pictured below.

Image

Open.

Image

Locked and loaded. :)

I can't believe how easy it is to post stuff and what not using the Moto Droid, I haven't even had to use my computer in about a week, this thing does everything!

Looking good, almost a shame you're making it reload manually since you have a three-way pilot. (Would that be someone who engages in group coitus while flying an aircraft? Hmm...).

Power should be impressive even at low pressures, what will you be operating at?

Ya, it's 1:45am here and I've got an exam tomorrow, doing the summer quarter... I still have to study... procrastinate much? I thought about making some sort of blow forward bolt, but for whatever reason I went with the manual loader. I plan to run it at around 125psi off a 20lb CO2 cylinder.

Great looking cannon. I hope the bumper is very good. That style of valve has a track record of breaking things.

On the 2MP camera, Even at 2 MP, the size and resolution has to be downgraded by editing to post the pictures here. Most of my photos posted here are shot with an older 2MP Cannon Camera.

A good lens for sharp photos is more important for posting here. Example photo below.

Proper exposure and composure that shows the subject clearly is all that is needed. High MP cameras are not needed. The photo clearly shows part of the proceedure to drill a 2.75 inch hole in a propane tank.

Well, I tried my best with this fixed acrylic lens. I figured these were acceptable at least. I wasn't trying to show off my awesome photography skills, just my mass of mutilated plumbing parts. I've seen some pretty horrific photos on here, even with a decent lens, it's still possible to make people want to cry when reading your post if you shake the camera, take photos in a dark room or stick your finger in front of the lens.

That's an awesome photo by the way.

And that valve is a mauler from launchpotatos.com, I got tired of leeking and exploding, so hopefully this thing is all that it's said to be.

I didn't recognize the valve as a Mauler at first. I was going to ask how you built the piston valve. I heard they work pretty good. I do like the photo showing the ball valve handle extension for the loading. I've been gathering ideas for ways to load golf balls. Due to the Grey ball in the valve, and the white pipe in the open postion, I presume you managed to sleeve a 2 inch ball valve with a 1.5 inch pipe. I'm impressed. Nice job. The bevels on the grey rings for trim looks great. A lot of thought went into this one.

Good looking cannon. I really like the low profile shape and design of it.
