Got a new-to-me anvil today - Peter Wright patent "solid wrought" marked for 146 lbs (1 1 6). Should on the whole be an improvement from my 104 lb cast-with-steel-top unit, assuming I get much time to play with either. Seemed reasonable at $200 within an hour's drive.
Has a few small defects on the top which I expect to be repairable. Reading up on what I can find the usual approach seems to be hardfacing rod (with Ernie waxing eloquent about hardfacing wire, but I don't have a wire welder and I do have 10 lbs of hardfacing rod, though I don't recall offhand what type it is).
Ernie's wire (dualshield MIG) method had the advantage of needing no preheat - all the rod use instructions instruct to preheat significantly. In any case thorough grinding to clean before hardfacing is recommended.
Any significant points I've missed? I prefer to ask the dumb questions in advance and save the pain of avoidable mistakes when possible...
