3rd degree burns are usually black or white, and they don't have blisters.
I have never had a large 3rd degree burn, but I think having your skin blasted off with a potato and then hit with a propane flame would look similar.

Ouch...In my room I was doing something really similar, looking into a mini combustion chamber that was loaded and testing the sparker. I then proceeded to burn part of my eyebrow. :lol:

oh, boy do I have a story!!! I was shooting potatoes, apples, slugs, and pieces of pumpkins as buckshot. well, lets just say I crammed several pounds of pumpkin down the barrel, charged it up to 60 psi, then shot it. the gun was backed up against a railroad tie, so it couldn't move backwards. the recoil forced the barrel back, snapping the pvc in several places. luckily, i was able to remove the fittings that needed replacing, and the cracked pipe without damaging the valve, the two 4 inch elbows,or one entire air chamber. the tee under the tee with the valve in it, and the coupler, reducer, and pipe connecting it to the elbow all needed replacing.


in the end, though the stove was even worse off... :lol:



here's it before

After.... (this is all from me shooting it, none of the damage was from anything else. that oven door consists of a sheet of 1/4 inch hardened aluminum, and 6 sheets of 1/16th inch thick steel. punctured like nothing @ 40-45 psi!!!

Image

Image


the white parts are the ones I replaced (duh! :roll: )

I learned my lesson. I can now lift it up by the barrel. this keeps it from wiggling, so It will be more accurate, and it prevents this from happening again!

above is one of the old fittings.

I'm glad this is not the end I'm at (unless I'm loading it)

Why oh why don't I have space to make a cannon like that? If only you had shot something a bit more solid :D

I feel your pain there, the lovely state of jersey is yet again making it diffucult for me to own guns and or cannons :cry: But on the topic on this thread, on my latest gun, when I was dry firing it the whole back of the bolt flew back into my hip, I was shooting from the hip. Left me with a nice bruise.

Schmanman: You need to fire a bag of ball bearings or something.

And, if you don't already, you might want to start wearing safety glasses when charging/firing. Who knows what unseen damage that shot might have caused in the form of micro fractures.

Be extra careful.

Something similar happened with this, once I forgot to put the piston blocker in, I was about to shoot it from the shoulder but for some reason shot it from the hip, the piston flew out and hit me in the stomach, drawing blood. The though that it could have been my eye was a sobering one :s

yep, I'm putting my controller box on a 50-75 foot cord soon.


I love this thing!


right now, it is almost totally covered in snow, except the barrel and valve.

since I take it to such low pressures, I still used it occasionally in the winter.

i doubt it. people get 3rd degree burns from sustained flames, which a properly fueled potato cannon wont produce. i have had molten/flaming plastic drop on my right middle index finger (scar is about 1/4 wide bu and inch) and it only made a 2nd degree burn. also, ive had the flame of a blowtorch brush against me, which caused a 1st degree burn. at most i think you'd get a 2nd degree burn from a cannon.

WARNING! GRAPHIC IMAGES


I got a new one. So the other night I was trying to drill a hole in a wooden dowel which I was holding, and the drill bit slipped off the dowel and into my left thumb, and drilled into my flesh under my thumb nail, which was "interesting". Guess thats what I get for being stupid and not clamping it down, oh well.
After containing the blood flow, I was able to snap a few pictures which a cool in a sort of painful way.

Heres the damage to the thumb. You can see the nice hole the bit dug in my thumb under the nail which the blood found rather convenient to travel in.

I also found it interesting that bits of my flesh were still stuck to the bit, showing how effective it was at boring into my thumb.
http://i122.photobucket.com/albums/o266 ... ll-bit.gif

Guess this is just an example of why when you are drilling something round, you should probably clamp it so something like this doesn't happen (not that I will, clamping usually incoveniences me).

There you go JSR :wink:

That is just so sadistically funny, the flesh clinging to the drill bit makes it even better!
Good luck with your next "injury" keep us informed too, you seem to be good at this kind of stuff! :D
