I want to build a cannon using the mauler valve...
Posted: Sat Dec 26, 2009 3:26 am
I saw the mauler valve, now I've got to have one...
I have a few questions first...
I have access to a beast of an air compressor so I want to build a monstrosity of a cannon. I can not find pressure rated 3" and 4" pvc in my area so I'll have to resort to ordering it from SGTC but is that a good idea? I've heard a few bad things about SGTC lately, and I've never ordered anything that big online...
SGTC limits PVC pipe orders to 4' 10" except SDR 21 1.5" which I can get in up to 9'
Using this valve at 125 psi, is it possible to break 800fps with a golf ball if I use a 8 or 9 foot barrel and 4' 10" long, 3" or 4" chamber?
Which should I use, 3" or 4" for the chamber?
Do cam-locks restrict air flow to a diameter less than 2"?
Can someone tell me what to punch into GGDT for it to simulate the mauler valve?
I've noticed with my other cannons with 2" air chambers, that the air chamber starts to get warm after firing the gun repeatedly. I think the stresses of being pressurized to 125psi and depressurized over and over causes the chamber to heat up, it always worries me.. Should I be worried when doing this with a 3" or 4" chamber? I would not like it to explode... Is a 4" chamber really safe at 125 psi?
I would really appreciate any help with GGDT... As well as any tips on how to layout this cannon!
Lastly,
For breach loading golf balls, I want use either a 1.5" ball valve reamed out to 1.7" with a hole on one side OR a 2" ball valve with a 1.7" insert... I guess I'll try both and see what happens...
