Hi Bill. That post anvil is some kind of weird non magnetic "manganese steel", I think. It is a bit tougher than mild steel. When I bought it, I just figured it was mild steel and mild steel should work for that type of anvil.
When you use coal you must first convert it to "coke", to drive off the sulfur and impurities. The steel can absorb sulfur and become very brittle. The fire should be deep enough so that a few inches of "coke" are between it and the tuyere, and a few inches over the top of the steel. |

Not sure as to the steel Tai uses for his post anvil, but from watching Tim Lively's dvd, you want to have some fuel over the top of your steel as well as under it. If you leave a part uncovered, it will not get nearly as hot. (The tip for example can be left out so as to not be overheated.

With a mild steel anvil you can planish the dents out with a hammer.
Coke is made by pre-burning the coal to drive off smoke and impurities, similar to making charcoal from wood. |

so i would just let the coal burn for awhile then add the steel and some more coal as needed?

You can tell when it turns to coke by when it starts to clump together and become light and fluffy.

I find it's safe to put the steel in when there is a whole lot less of the nasty yellow smoke comming off the fire. Once its coke you shouldn't really see anything comming out of it.

Greetings, BobO,
Glad to see you show up. I like to drink Coke and forge with wood. I like my RR track anvil. If you can get it cut it should make a good post pounder. Or maybe just stand it up as is. |
