It appears as though it is square from afar, but it is indeed round. I measured the heel of the anvil and it is over 1 inch so it still has some mass. It's my understanding that this anvil is forged and therefore doesn't have a separate steel plate that is welded to the body. Maybe someone else could clarify this. And yes, the propane tank besided the anvil has been moved. Here is a picture pre-machining and also one that shows the round (drifting?) hole.

Does anyone know an inexpensive non-destructive way to make a square hole for my anvil? So I got took my little 20 kilo (about 44#) Peddinghaus anvil to a cnc machine shop hoping they could mill a square hole so I can make some bottom tooling for it. In the process I had him re-surface the top. So when I went to pick up the anvil last night, he told me he was unable to machine the square hole because this metal was tough stuff, in fact he has broken some carbide bits while re-surfacing it. I wish I had told him that the edge of the anvil was supposed to have a tapered radius because he ended up taking off a little more than I had expected (about a 1/4''). Lesson learned!

The forge is made out of 1/16" plate, and we plan on lining it with two layers of kaowool or superwool, castable refractory, the itc 100, and perhaps the greenpack 85. The burner design is from Porter's book, except we are using 1'' instead of 3/4'' for the nipple. http://www.iforgeiron.com/gallery/image/38546-20141031-170030/ http://www.iforgeiron.com/gallery/image/38545-20141031-170011/ http://www.iforgeiron.com/gallery/image/38544-20141031-161959-1/ http://www.iforgeiron.com/gallery/image/38543-20141031-162007/

Hi Thomas, Thanks for reminding me to update my location. I am in Austin, Texas.

Hello, Long time lurker here at iforgeiron and finally posting. I'm looking for recommendations for sources fairly priced Superwool, ITC 100 and Castable Refractory. Thanks, Ede
