I made some changes to my propane burner for my foundry. Alex and I explain what changed, and why. There are also a few nice demonstrations of its awesome power! It’s made from a gas regulator hose, two pieces of 3/8″ x 3&4″ pipe, a ball valve, a 1/2″ bolt, and a .030 MIG welding tip. The burner tube that surrounds all this is a 1.25″ x 12″ pipe, and 6 socket head cap screws are used to position the propane pipe inside the burner tube.
