If you can afford the new anvil then buy it. Unless its a cheap cast iron piece of junk. But you just spent all your money on an anvil. You still need a forge and tools etc. Do as Jasent and JHCC have recomended. You can get into this cheaper that way. Ebay is a risky option for getting an anvil. You have to see it in person and test it. I bought a 16lb sledge hammer from ebay for 35usd shipped, and bored a hole in a stump to hold it and it is surprising how well it works. You have to learn basic blacksmithing skills before doing historical weapons etc. Such as drawing out, square tapers, spreading, 90 degree square corners, punching, drifting etc. All this can be done on on a simple piece of mild steel, etc. Look for a blacksmithing group in your area. They will have more knowledge and resources then you can get on your own. And I think there might be a smith or 50 in the UK that can help. Welcome to the addiction!
