As a matter of possible interest, I am posting the results of my preceding inquiries and the valuable responses. Impatient to start hammering, I abandoned making my own anvil and bought a 35 kg Peddinghaus and made a stand from bolted lumber and angle iron, a design copied from pics on this forum. It's a small but decent anvil that could probably be resold for a decent price to upgrade someday. I tried to fold and forge-weld a piece of flat iron with limited success. I brazenly disregarded proper beginner humility and attempted to hammer a section of lawnmower blade into a knife which cracked and failed disastrously. I wanted to take a shot at it just to get me thinking about the task. Starting with the right material could be important, huh. And I made a couple S-hooks which are actually useful. I also melted some copper pipe in the crucible. It was all quite enjoyable. I'll probably make some forging tools next like a crucible pouring tool.
Also, I wanted to comment on the tuyere. Next to the S-hooks is the pitiful remainder of the original black iron pipe tuyere after melting the copper. I mean, I knew such tuyeres were considered consumable, but that one melted in one day! So, I degalvanized (in vinegar) some steel pipe and poured Kast-o-lite into a can around the pipe to make an insulated tuyere. Shown in the pic is that tuyere after one blacksmithing session which included coke so it could have been fairly hot. It seems to be holding up but we'll see how it looks after using the crucible with it. I figure it will probably still melt but am hoping for a lifespan of weeks or months rather than hours .
