Hmm, anyone would think Halloween was just around the corner....


 :doh:

Seriously funky work, though, looks great! How about a flame-thrower in the nose....?  :zap:

Nice one Wes.

Obviously you got all the gas out before you cut or you won't have posted, right? Or as AdeV said, a flame thrower out the nose. :bugeye:

I think it needs a couple of feet and some arms waving around, too.

how do u cut that with out blowing it up. a real close friend of mine was a certified welder and was working on one of those it blew up killed him and 4 others in the shop.
so ive never touched one of those. they (the fire department) said he did everything right but that it was one of those times where it just happened.

A freind of mine shoots a hole thru his. Then he lets it set a few months before he cuts into them.

Could be your freind didn't wait long enough to get all the gas out. I've done it. I took the valve off then let it sit with the opening down so all the gas drains out. Propane is heavier then air. I wonder if he filled it with water and had a steam explosion.

Woner if it was something else that caused the explosion.

Not an exercise everybody should try.

I couldn't get the valve off. I tried!!! I took the valve packing nut off and the handle then comes out. This left a 3/8ish hole into the tank. I blew compressed air into the tank several times until the air coming back out didn't smell like Propane any more.

Decided to put feet and arms on it. There is a hole in the back for a weed burner :ddb:

Scrounged around for some feet. Brackets that were cut wrong. I made the toes out of rolls out  of a junk roller bearing. He will look classy with a top hat I think.

Finally found some time. Jack sprouted some arms and a busted hook :headbang: Still looking for a hand. Maybe a little hand saw?




Getting closer :wave:

That's great, Wes.  I think the glove on the one are is just right as it is.  Makes you think "What's he got
under that glove?  A claw?" 
Just right for a spooky night!  You're an artistic guy.

:bugeye: That is seriously creepy.  It would undoubtedly give me a start coming upon it suddenly.  Put a flame bar in it (such as



and hang some actuators on your front door -- when someone comes a-calling, Mister Heid can answer it.

Keep emergency services on your speed-dial, though, just in case it's Aunt Maudie.. you might need a hearse to take 'er away.

I am gobsmacked at the wonder of the thing.  :bow:

Too much fire :zap:


Have one or two little things to finish up.

That little dude is cool! Gives me an idea...


how do u cut that with out blowing it up. a real close friend of mine was a certified welder and was working on one of those it blew up killed him and 4 others in the shop.
so ive never touched one of those. they (the fire department) said he did everything right but that it was one of those times where it just happened.

Pressure vessels need a bit of respect but they are not magic, if you do everything right there is very limited risk of any harm. You can't "do everything right" and still cause a massive explosion. Unless it was a very different sort of job he was doing than simply scrapping an empty tank.

I've cut a fair few of these up, I was curious about all the rumours about large explosions and used to be into combustion cannons so obviously I tried it.

I filled a 13kg tank with water to determine the volume and injected a stoich mix of propane and ignited it from a distance. WHAM, but no shrapnel, no damage to the cylinder.

I did the same with a random volume of acetylene (after clearing the fumes out with an air line). Big bang, bit of a flame out of the front, but no failure of the cylinder, no shrapnel, no death and destruction.

Conclusion I came to is there is no chance that a cylinder with the valve removed creates a danger of a large shrapnel causing explosion. You ARE at risk of losing your eyebrows if you've already cut a bit of a hole in it though.
I think any large explosions caused by similar circumstance are due to people weighing into a full or still pressurised cylinder with a torch with no thought to emptying it, perhaps a mix up of tanks or something. Filling it with water and closing the valve could create a steam explosion too.

 That said I fill them with water then drain it back out anyway to displace any propane to avoid losing an eyebrow or 2. Probably the riskiest part of this is opening the valve and releasing the residual propane.
