It has been a long time since I have been on the forum, but I thought I would show you guys one of the things I have built this summer.
I have had the idea to build a stand that is completely remote control, and given that I already had a semi-auto golf ball cannon it made it easy to get multiple shots off from a distance. Since making the video, I have made some minor tweaks to adjust the finer movements in the vertical direction. I have changed the control box, and the servo since the video, as well as some changes to the piston
I have had the base, which is the bottom of an old recliner just sitting in the basement for a long time and decided it was a good candidate for a cannon stand.
please, I don't want to hear anything about the primer stains. The cannon used is an old cannon from a while ago, and the parts I used for the piston are parts that were just lying around. The whole thing will be painted when I get enough time, and figure out how I want to do it

That's a lot of pipe. 
Very cool, integration of a lot of neat features. I especially approve of the use of a air cylinder for movement. What's the max elevation/traverse? It seems to handle recoil well enough without needing any compensation.

Nice

Thanks for the comments, the damage is quite good, I haven't had a chance to put together a video of the damage quite yet, I don't exactly know the max elevation, but Ill guess somewhere around 45° maybe a little less. I don't really need anymore than that, but if I want more later all I have to do is lengthen those two side two by fours. But then I run the risk it tipping if there is too much recoil. It can spin a full 360° if I let it. Eventually I would like to make it radio controlled, and loose all the wires, but this is what I had without spending a bunch of money for a radio controlled setup. I also have a larger 4" chamber and a smaller 2" chamber for harder, and faster shots. The front barrel is also threaded so I can change it out with any of my 8 or so different barrels. The whole setup can be easily broken up into 4 pieces for easy transport in just under 30 seconds.

Thank you for the interest, I have another cannon in the works that will hopefully be up here soon

I cant show you, but I can tell you that it is a pump action spud gun. Oh and I must say I am a big fan of your work, and am really interested to see how your latest project will turn out(the monster with an 8" chamber)
Nice gun bro! I love the "sentry turret" type of setup! keep up the good work!!

Sweet, excellent work!
This is my one gripe, it definitely needs to be on a recoilling mount, I don't think it's doing any good to the elevation system to let it absorb the blow.Blitz wrote:It seems to handle recoil well enough without needing any compensation.

Yep! I used to like watching them set up around 2pm in EPCOT, seeing the barges go underneath the bridges into the Showcase Lagoon.Solar wrote:The fireworks systems at Disney use air cylinders to adjust the angle and direction as well. Very nice.
Many pyrotechnics prefer HDPE for their mortar tubes too, by the way.

Actually one of the reasons I chose to use a pneumatic piston for the elevation is because the piston can absorb the recoil. When the cannon comes back, the piston compresses, and pushes back up again. There is no leak in the piston, and the elevation after each shot stays exactly the same and before the shot. I don't think I mentioned it before, but at most, there is only 15psi in the piston at any given time.
