Last thursday I made a brake drum forge to take to a hammer-in. I lined it with red mud and ash mixture, packed in with straw which controlled the cracking pretty well. I put some more mud in the small cracks but they still opened a bit when it dried.
It performed pretty well (4 hrs), there is one soft spot that needs more clay/ash and a glassy spot where the (stainless drain) grate warped and let air come up the side. I was wondering why I was having trouble controlling the fire in that area...
Good Luck! |
