Bob's forge build is the one most first-timers copy: empty propane tank, ceramic blanket, refractory cement, a Frosty-T or Venturi burner. Watch the part about rigidizing the blanket; loose ceramic fiber is bad for your lungs.

Right around what the post says, give or take shipping.

Followed along, got it done in about twice the time quoted, but it is done and it works.

I did the same repair last month and your step 3 is where I got stuck. Wish I had this then.

Unplug it. Always. Takes two seconds and the worst case otherwise is a trip to the ER.
