This anvil search is not a new thing. I've been looking around for several months. I started out looking for a cutoff I could put into a bucket of cement, but GA scrapyards don't let you out there anymore, and consequently are recycling their steel. I've called at least 30 places, and got the same answer. As for railroad track, it sounds easy to find, but its just not so. My uncle has a 16" piece of track sitting around in Louisianna, but he's old and its just too much for him to handle shipping it. I called a big steel supplier and they wanted pretty high money for a cutoff that wasn't hardened. If I'm going to pay good money why not get the real thing. A welder last week told me where to go junk shopping up north of me, and I plan to do that soon.
As for convincing the ex in-law in Mississippi, I'm going to try that regardless. Its my great grandaddy Daniels anvil. I'd feel honored to pound the same one he did when he got back from WW1. It would have family history. It would be the only thing of his that I own, and it would just mean a lot to me. Additionally that woman is just letting it rust in a shed, and I'm worried she may sell it or something.
On top of all of this is that the guys in the makers section say that its a waste a lot of time improvising an "anvil". The more mass you put behind the hammer the more steel you move on each hit. There is a noticable performance difference to a good anvil. Plus the hardie hole is frigging useful as hell, and no post vise can compare.
I've been training a little with one of the guys in the makers section. I'm not of the mindset to invest what he has on his forges, anvils, power hammer and KMG grinders, but I can see how using the best tools gives him superior results very efficiently.
Anyway, thanks for the suggestions, and for listning to my anvil rant. If I find one of those cutoffs for $<.50/lb I'm certainly game, but I'm not paying more because I can get an old anvil for ~$1/lb or less if I look hard enough. One is all you need, so I don't mind being patient and finding a good quality tool.
