SPUD-nik

[woods]

Thought I would share the spud cannon I built with you guys for a few laughs. I seem to overdo everything, but it's fun.

Aim at at McDonalds... they could make fries from your spent rounds...

[woods]

They are only about 5 miles from me, I could get close.

[forrestbump]

Well... whatever misses, you could sell to KFC as mashed potatos... just a thought for some extra income...

Way to reuse . The sledge counter weight. Nice! What kind of vavle did you use to release the pressure?

[woods]

I had a large ball valve for water and I used an old air powered ram off of an air shifter to flip the ball valve open. That vid was with 70 psi in the tank. I have ran it up to 130, but the spud just turns to mist. it will take around 100 and still stay togther. The thing actually has a little bit of a shockwave when you touch it off.

i have seen similar things like this before. and i always wondered if they could go further if packing was around the tater. so that all the air would give it a better push. liek when myth busters were launching chicken at the airplane windshield.

No room for packing on this. I actually put a sharpe edge around the end of the barrel, so it cuts the spud as I pack it down into the barrel.

I figured you did that. I have seen ones made to use hair spray and they are cool but yours puts them to shame.
One of the Steam Plants I worked at once in a while had built an Oxygen acetylene cannon and it was in the back of the machine shop. They would fill it up and fire it at noon once in a while. I would scare the mess out of you. Especially when one of the younger guys would fill it.

I tried an oxy acetylene spud gun before this one. Most of the time it just turned the spud into a vapor. I hit it right ever now and then, but it made me twtichy.

Wadding behind the spud?? Maybe a big wad of cotton or something? Keep the spud in tact and still break the record for the worlds fastest fries to go! 100psi I say 200psi

I think it comes apart mostly do to the speed on the spud. Many times they seem to break up about 50 feet out. I have cut a spud to size, froze it, cranked it up to 210 psi and let her rip. I'll let you know how far it went as soon as it stops circling the globe. The sound that it made was just insane. The pressure wave off of it was a lot like that of a Barrett .50.
