I am building a cannon with twin 3' by 4" chambers. I wanted to use twin 2 in Mauler Valves. My question is should my tee combining the chambers be 2 inch or bigger. Also, the valves are connecting to the chambers and elbowing up the tee. I was thinking 2" elbows as well? Any input would be great.
Thanks

i think you should use as big pipe as you can till you get to the barrell..
btw what size is your barrell going to be?

I wanted to use a golfball barrel and a 2.5" barrel.

well i would say go with 2 inch.

So your configuration is two 4"x36" chambers, both connected to mauler valves. The mauler valves are then connected by a tee, which then is connected to the barrel.

If this is true, use a 3" tee to connect the two mauler valves. It will insure that no flow is lost, and will not have too much dead space either.

To connect the chambers to the mauler valves, 2" elbows will be fine

Thanks for all the info. From what i have told you what kind of power can i expect from this. Thanks again guys

It depends on the barrel length and pressure.

But if you use enough of both, you'll get a crapload of power from the twin valves.

if you put on a six foot barrel and pump it to 120psi, dont expect to find the golf balls your shooting out if it

Or anything else for that matter!
Don't use Bondo slugs, they don't hold together very well at high speeds. I hear ice works nicely.

Use pykrete, which is a combination of ice and sawdust which is much much stronger than regular ice alone

Thanks for the help you guys ROCK.
