Hmm, if somebody said they found 16 pieces of 1/4" sheet metal and they wanted to weld them all around like you show in your drawing to make a 4" wide anvil, I would not think it's a good idea. Eight 1/2" pieces, four 1" pieces, two 2" pieces? At what point does the concept of an anvil made from pieces welded only around the perimeter start to make sense (if it ever does)? I don't have a good answer for it, but I would not want to waste my time on it just based on that. And then there is also the question of how to weld hardened stainless steel...
Hubert my friend ...let me tell you something about me .I make a lot of money, and I mean that by Western standards not Macedonian .I can afford to buy a lot of things. It is not a problem for me to order from Japan fishing reel for a thousand euros and a fishing rod for 500 euros .... So I can afford to buy best belt grinders ,HT ovens or whatever I want associated with the making of knives . Only problem is where to buy them????????? Here in Macedonia ??? Should I pay for transportation from USA to here ?? Some day I broke the last drill bits /4mm/ for drilling ceramics and all i can find here is some junk from China .So i need to order them from Austria , Germany .........
Now about anvil.........there used to be a dozen blacksmiths in my town, no anvils! They most likely ended up in the scrap as scrap iron.In fact, there was one blacksmith ...only one now , two hundred meters from me. An old man, he opens a shop every day and doesn't do anything, he spends his retirement days with some other old people there talking . . .
I offered him to buy that anvil and that I would accept the price without bargaining.....He just laughed and said even if I paid him in gold in the weight of the anvil, he wouldn't sell it to me !
So , do you have any idea how and where can I find and buy Anvil , and not to cost me a kidney ?
Just one more thing ............... $ 4,000 for four small Al wheels, a bit of steel and 2Hp motor ?????? Not in this life my friend , not in this life ! I would build it my self for 200 $ !
