Demonstrating the Metal Stump that I made for metal shaping..........I've gotten a couple comments/questions on the tank itself... I didn't really think it would be necessary to say since I would be directing this video to fabricators who should know about these tanks.. But anyone can see these videos, and may not know the dangers. So here's a cut and paste of some common sense (If you are a Welder/Fabricator) precautions..
It's not a Fuel Tank... it was an old Oxygen, or Argon Tank, or CO2 tank.. You don't want to use a Hydrogen Tank, or a tank that held anything that's flammable. An Acetylene tank not only flammable, it is the wrong construction, as it is filled with cork and doesn't have the concave bottom and it's made of too thin of material. Propane tanks are too thin as well, and obviously flammable.. If you do use an Oxygen Tank, obviously it is an oxidizer and while it doesn't burn on it's own, it does accelerate a fire. So it's a good idea to purge the tank a few times with your air compressor. Or unscrew the valve from the top and drop an air hose in the tank and let it blow out (dilute) any residual oxygen.......... I answered this question about 5 years ago, so it's way down in the comments.. Here's a copy and paste of the answer I gave someone who said they were going to use an acetylene bottle, back then....... First ...Don't use an Acetylene bottle..!!! They are constructed completely different and it will be dangerous..!!! The bottom is shaped differently and not usable.. They are filled with cork to absorb the Acetone.. and they are VERY unstable.. you could blow yourself up.. !!!
Use an old Oxy or Argon or C02 bottle..
Don't use an Oxy Acetylene torch to cut the bottle.. Even if it's empty and purged, you can still introduce un-burned fuel and oxidizer into the bottle from the torch, and blow yourself up!!! ... Use a saw.. or a plasma cutter... I cut mine in half with a band saw first. Then after the end was open I used a torch to cut the shapes that I used for dollies.
