Just wondering if any of you guys has attempted to repurpose a coleman
propane tank - the little 1 lb critters - and have cut one open? What
thickness is the sheet metal? I need to make a replacement car tank
for an old single cyl engine - Like to make it about 2 liters which
would be roughly 11 or 12 inches long with the 3.5 inch diameter tank.

Just cut the bottoms off 2 tanks, cut the gas fittings off the top,
tig them together and tig the holes shut and add a filler neck and
fuel outlrt boss.

Just want to know how solid the tank would be - how much abuse it
would take without getting dented.

I read that medieval combat helmets made from barbecue propane cylinders
dent easily.

"The typical propane tank would probably only burst with propane tank max pressure rating over 6895 kPa or 1,000 PSIG."

Old fire extinguishers are larger.

Look at the lap seam in the middle , that'll tell you how thick .
I've used the short fat ones for aluminum crucibles , IIRC they are
around 18-20ga give or take . They're actually thicker than the stock
most of those small tanks are made of .

In any case they can't be any worse than the sheet metal tanks that come
on some power tools.
