Mini Mega Launcher

Unread postAuthor: PCGUY » Mon Jan 31, 2005 8:24 pm

<div align="center">MINI MEGA LAUNCHER

Provided By Luckythirteen - <a href="http://www.koolpages.com/potatohell/">http://www.koolpages.com/potatohell/</a>

This is pretty much a copy of Joel's Mega-Launcher, but using my sprinkler valves instead. Don't let the sprinkler valves and 1 in. PVC fool you, this gun puts a baseball through 1/2 in. plywood every time, like it's not even there. This gun also has a 1.5 in. barrel and a 2.5 in. barrel.
I have recently built a piston valve that works perfectly. It's 3 inches in, and 2 inches out. When I get around to building another one (hopefully very soon), the two will be teamed up to replace the tired sprinkler valves currently used on this gun. Let the devastation begin! One of the first things i will shoot to pieces is the tree that is early visible in the left picture above. Its full of termites and has to go. If I can't shoot out the base, at least it will be fun trying.

The sprinkler valve I modified to get more power. I didn't want to spend $100 on supah valves from <a href="http://www.spudtech.com/">SpudTech.com </a> so I tried to make a valve that would be very powerful and inexpensive. By no means is it as powerful as a supah valve but in comparison to an ordinary sprinkler valve, it adds a lot of power. Air flow is still restricted but the speed at which the valve opens is greatly increased which is what gives it the extra power.

Below used to be a 4 ft. x 8 ft. sheet of plywood, but after shooting it a few times with my big cannon, this is all that's left.

hmmm, i don't know about that.
Aren't sprinkler valves like 15-20 bux a piece at most.

THats only 100 bux for the whole guns valve system while 2 supahs would be 200 bux.
I think that once he replaces the sprinklers with pistons it should be a fricken beast.
But still not as strong as supahs, I would think. yeah

Im not sure as to what a 'Supah Valve' is. Sorry. If you wouldn't mind, could you elaborate on this specific subject? :(

a supah valve is the best when it comes to pneumatic valves, joel suprise sells them, he owns and operates http://www.spudtech.com joel wont tell people how a supah works, but its got the quick opening of a diaphragm valve with the full flow of a piston valve. it requires alot of machining, so even if you knew how they worked you couldnt build one without alot of access to tools. it takes joel 118 minutes to put one together. he is working on the megah valve which uses a 4" tee with 3" openings instead of the supah's 3" tee with 2" openings, but he's not selling them to the public yet

there, eleaborated enough?

hmmm. The barrel to Chamber connections are too freakin small!!! Your creating a bottleneck, It looks like your using a 4" chamber connected to a 1" connection! unbelievable!

Im seeing this everywhere, increase the size of the connections to some degree of uniformity with the diameter of the chamber and barrel and you would see a massive increase in muzzle velocity, even without supah valves.

*exasperated*
1" sprinkler valves only flow eqivelent to a 9/16" hole - the sprinkler valves, not the pipe, is the bottelneck. However, the 1" pipe might be structualy deficient when dealing with recoil, although it appears to be doing fine.
