Re: Battery Gun

One of my first launchers was a battery launcher. I used sprinkler valves with battery operated solenoids. Performance was garbage, but it was fun. It was a fun thing and you also have a fun thing. I'd like to see yours work.

Re: Two-stage hybrid

Predicting it's behavior would be complicated and difficult, but I can see this possibly working. It's funny to see this because I had a similar idea except I thought about using a hand crank to compress the chamber B side. A gear reduction and a worm gear or ACME thread with a piston to compress th...

Re: HELP ME ESTIMATE THE DISTANCE OF THESE SHOTS

I think it's BLM land where I go, but I've never actually looked for a truly isolated spot. Your idea sounds good and I might end up doing that, but I won't want to go alone and without a good medical kit to stop the bleeding at a minimum. I have only one concern that is on my mind and is partially ...

Whoa, I've never heard of a stand up bike before. Nice work for sure. Are they hard to ride?

Re: Water pressurized spud gun?

The water from your hose can be used to displace the air in a chamber and pressurize it. The air pressure is limited to your water pressure coming from the hose. You would only do this if you didn't have a bike pump or air compressor.

Re: HELP ME ESTIMATE THE DISTANCE OF THESE SHOTS

Using Trig sounds like a fun way to do it. Good ideas! Also, you're right about not being able to simply pace it out. It's not safe to walk that far out since it's an open range.

HELP ME ESTIMATE THE DISTANCE OF THESE SHOTS

Not much to work with, but you can see the impact of the first shot just above the propane bottle. 8 OZ soda cans at 3X, approx 30deg angle (you can judge angle yourself from video), approx 5 second flight time. My guess is maybe 200 yards? Maybe 250? [youtube]https://youtu.be/UvQ_2btZp58[/youtube]

Re: Water pressurized spud gun?

Water is an incompressible fluid, so I'm not sure there is any way to use it to fire a potato. I think A water rocket uses the mass of the heavy water as a means of thrust. In a spud gun, you want the spring action of the compressed air to all act on the potato. If the energy is used to also shoot o...

Re: Planning the new hybrid

Interesting design you have here. I've considered trying to make one myself, but making it simple and reliable presents challenges that I haven't thought through yet. Nice work!

LOL that was funny the way it bounced off the can and flipped around in the air. Nice!

Re: Oxygen tank

Maybe I'm just ignorant, a chicken, or both, but I'd never use something at 3000psi unless it was designed for it, labeled for it and according to manufacturer instructions exactly. Not chicken. Maybe a tiny bit ignorant if by "ignorant" you simply mean, "not a professional in the field of compress...

Re: Oxygen tank

You guys are talking about some insane pressure. I think my last cannon is at least fairly beefy (at least I hope it is) and I'm still afraid of the thing at what should be around 300psi max. Maybe I'm just ignorant, a chicken, or both, but I'd never use something at 3000psi unless it was designed f...

Re: Cooking up a little something...

Thanks Mark! This cannon would obviously be pretty impossible to make with a drill press and hand tools, which is also the reason why the Striker looked cool but totally sucked in terms of function. Even so, this cannon took a ton of hard work and effort. It took a lot of aggressive sanding, buffing...

Re: Thoughts on my piston valve design

I'll just say I don't know how the flat head screw will do for securing the rubber. I noticed it right away but didn't want to appear as being too picky since it's not my cannon after all, but it's best to try and help I think. It might screw in far and force the rubber to move outward on the angled...
