I'd decided a good while back that a diagonal pein hammer would be really good to have, but with the price of good hammers it'd have to wait a while.
One of my "shopping" trips to my favorite scrapyard turned up some offfall from a local machine shop. 55 gallon drum of short pieces of solids in round, hex and one NICE piece of square 1 3/4" X 5" "mystery metal".
Last Thursday I punched the eye and rough cut and ground the pein end, today I refined the eye, forged the pein the rest of the way and slightly radiused the face.
After lightly grinding to the best finish I could and finishing the face and pein with a file I mixed up a batch of Super Quench and hoped my new hammer would harden. Well, it did, nicely. A file would just slide across the surface removing nothing but a bit of scale.
I then used my OA torch with the cutting head to heat the area around the eye until the pein face started to turn straw colored. By the time I got the torch shut off and got the tongs on the head it had reached dark straw beginning to show purple on the far corners. Quenched only the first half or so of the pein end keeping a good bit of heat in the eye area. Repeat process with the face end, again quenching only about 2/3 of the head portion hoping the middle would stay soft enough to not break. So far it looks like it's working. Couple of missed slicks and I got really good bounce, plus no "dings" in either the hammer face of anvil.
Except for the weight, (right at 4 lb) I'm pleaded with my first attempt at making a hammer. Maybe next time I'll start with stock a little shorter, hoping for around 2 1/2 lb.
Great way to spend one of my days off.:D
