Cobra Venom Hybrid
Cannon
Not just another cannon
The cannon has been engineered for a high degree of
safety when use under 2X with propane or MAPP. The
factor of safety before the material bends for enough so
that it does not return to it’s original shape is 4.2
under a load of 200psi. The cannon can clearly handle
higher pressures, but 2X is plenty of power and the
cannon has been tuned to be power efficient with its C:B
ratio operating under 2X while keeping safety the
highest possible. Velocity benefits diminish when going
past 2X without using a very heavy projectile to take
advantage of the additional thrust, or a longer barrel
to allow the projectile to be pushed farther by the
extra gasses. The cannon was machined and welded out of
100% 6061-T6 aluminum. It was then annealed to relieve
stress and then re heat treated back to the T6 condition
for maximum strength.
This rifle is currently being tested.
So far at 115PSI it has surpassed my every expectation
launching a 50 cal. slug through just about anything you
want to shoot. A dot scope will be added for further
testing.
The barrel is a brass/copper barrel
sleeved with PVC. There is a 115PSI blow off
valve for safety, and a Schrader valve for easily filling
the cannon. This gun also offers you the
option to have a continuous feed from a compressor, or have
the CO2 package added.
The porting is 1.5" in diameter, since
you can't actually see down the barrel in these pictures.
The piston is made of a shampoo bottle cut in half and then
filled with hot glue. It's fully serviceable; the chamber,
the piston housing, the piston, and the pilot valve are all
accessible and replaceable without having to replace
anything else with it. The air chamber can actual be
increased in size if necessary, since the threaded cap out
the front could be replaced with a much longer pipe. For
now, the threads on the barrel allow me to shoot anything
else until I work out the net attachment (like the 150 golf
balls I scrounged from outside the shooting range one
afternoon, freebie!). Oh, and the flame decals increase the
muzzle velocity substantially. Enjoy. I sure do.

PPCTACG001
in the construction of his new cannon.)

This fine pneumatic potato cannon is the work
of Alex Neiman. He combines multiple designs to come up with
his superb cannon EA25PAC.
What a great effort.
To finish the cannon, Alex says he wants to paint and add
cool decals to his spud gun.
Alex has put a lot of thought and work into his design. If
you would like to ask Alex some questions about his
instrument of mayhem, send him an email by clicking on his
