Probably stationary. I am just going to use about 4-6" of it. The end with the large opening, and then the fitting with the holes for my tyre. I am going to get it turned down or cut.

Hey guys and gals. I have been wanting to build me a coal forge to go along with my gasser. I was going to use a brake drum but I got my hands on an accumulator off of an old hydraulic system. I think it will work for the fire pot and tyre. I am gonna cut it and use the end with the big opening. Take a look and give me your opinions.

I am not sure how big of an anvil you are referring to? But here is a link to a video that clearly shows a bridge anvil in use.

I agree

I have been using the forge and for general forging it works great. But I have noticed that when I crank up the gas and air for welding I have a problem. The high temp mortar begins to melt in one spot. I thought at first it was from the borax, but I think now that it is more heat developing at the rear burner. Jymm Hoffman mentioned that I may have to adjust the burner tips to equalize the flow. I think he was correct. I believe this is what is happening: At lower temps (lower air/fuel pressure) the burners are or appear to be equal. This is probably not the case bu it is hard to tell. Then when I turn up the air/fuel pressure for welding the pressure/heat increases and creates a hot spot on the floor in front of the rear burner. Over a period of time it eventually heats the mortar to a point that it melts and then melts the ceramic wool. I think I can use some stainless steel pot scrubber (really coarse) to slow down the flow to the rear burner. I am going to remove the pipe plug from the end of my burner assembly and insert the ss wool between the two burners. This should restrict the flow to the rear burner. If any one else has any ideas please post. I will try to get some pictures posted.
