Cutting up old propane cylinder.
I used a plasma cutter, with a plastic guide to get as square a
cut
as possible. I used a scrap of 3/16" flexible plastic with a straight
edge and bound it to the tank with a strap. Lining up the straight
edge assures a square
cut. (This is a great trick for marking or cutting
any cylindrical material.) Photo D shows how tight the two cuts came
out.
Rolling the tank along wooden 2x4s allowed me to
cut in one continuous
pass. This tank is nearly 3/16" thick! Two cuts were done in about
10 minutes.
After cutting, I had to clean out the tank.....that was the hardest part
of the whole project. I used an angle grinder with wire wheel. RUSTY!
