Make wood burning stove calor gas bottle,wooden rabbit hutch plans,wood carvers warehouse - PDF Review
Dont want to post something that tells people to cut open a gas bottle with a stihl saw - now if you want to ask me how I did it thats different.
Remove the top valve and replace it with a large butterfly valve so that you can control the fire, and make a hole with a small door at the bottom of the bottle to feed the fire and to put the wood chippings in for smoking.
I am now on the lookout for a large calor bottle and the help of a mad welder (I know a few of them!!) and a bucket of fish!
Fill with water a couple of times,leave it overnight(24 hours),empty water out,fill with sand and do your cutting with the sand inside bottle.
I have tried emptying the water out before cutting, assuming the water would displace the gas vapor, but it don't, you can still get a big old flashback off it, not worth the cost in soiled underpants, and new eyebrows.
Just read elsewhere due to the fact the gas is heavier than air, leave it upturned to evacuate any vapours.
I personally wouldn't trying to fill a gas bottle with boiling water or steam apart form being unnecessary cold water is fine, I reckon the chance of scalding yourself is quite probable.
Apart from that the gas is also heavier than air and rolls along the ground, which is why taking the valve off is a bad idea unless it has been purged.
But that is just the mercaptan (added to make the gas smell) that has sunk into the surface of the cylinder.
