Before I moved house, I had a ceramic chip forge running off mains gas. Useful but not used very often. Here we have no mains gas being 'out in the sticks', so it has remained packed and not recomissioned.
So yesterday I needed to flatten a 1/2" plate ( mounting flange for a digger bucket). Dug out the ceramic forge, coupled to a propane cylinder , and in minutes it was red hot and ready for thumping on the anvil. Today I needed a starting handle for an old tractor - involved two tight 90 degree bends in a 1" bar. You guessed it - roll out the ceramic chip forge and in minutes the bends were made effortlessly.
I'd swear it runs far better off a propanne cylinder than it did off mains gas!
