Hey all, I just picked up this 5th foot colonial anvil this afternoon, appears to be stamped 1-1-2 (circle) giving a stone weight of 142# bathroom scale says 143# so that checks with chart. Not sure what the circle means other than perhaps an inspectors mark or added by an owner over the years. Looking for any additional info. Thank you all in advance.
Hello again peoples. So, I picked up my theoretical future starter anvil today. A local guy sold me three 7x7" blocks of some unidentified steel. I have a few spark pictures so I'm hoping someone can give me a bit of input on that as to the carbon content of the metal, roughly speaking anyway. They also came with another chunk that is about 2x9, estimated. Didn't bother to measure since I'm not actually sure what I want to do with that piece yet. Ok, so here are the three as I bought them. The guy who sold them said he got them from a local machine shop. I think he might have had them cut to dimension. I apologize for crappy quality, my phone camera only does so much. Anyway, onward. I ended up working on the far left block. This is how it looked when I started. The rebound in this state using a 2 1/2 lb cross pein is... well, pretty minimal. My workbench probably didn't help but the hammer only bounced back about an inch and a half, maybe two inches. Didn't bounce more than twice with a loose grip. Anyway, took an angle grinder to it. Started with a 36 grit flap disk to remove the rust and what I assume was mill scale, then moved to a 60 grit to get a tiny bit of polish going. I also ended up choosing a different side that was ever so slightly flatter and had less protrusions. Ended up looking like this. There are still some small pits in the surface and a few scratches (I'm not terribly experienced with flap disks). In this state my hammer does dig into it just a bit, but the hammer face also needs to be dressed so that might have been part of the issue. Ok, on to spark testing, which I actually did before the polish. (For any safety minded people, I was wearing earplugs and safety glasses, as was my photographer, and yes, I should have been wearing long sleeves but I was just a little overexcited to get into the project) This is just about the best photo I could get of the sparks. I was comparing to a rough diagram of common spark appearance based on metal type and by my estimate it's most likely medium carbon but I'll leave that up to more expert-ish opinion. Anyway, if someone could help me out with a carbon estimate that would be great. Also, I'm considering whether or not to try and heat treat or harden the surface, since that would entail dragging this thing about 100 miles south to where my friend and co-conspirator on this could help me slap together a coal pit and stuff. I don't have any experience heat treating anything, much less a BLOCK of steel, so tips would be appreciated as well. Also just kind of wanted to showcase that I'm not just sitting around trying to keyboard commando all this stuff together. Thanks chaps!
