After the monster

After the fire monster, I thought a similar creature with case hardened steel rollers for jaws would be just the thing. I milled grooves in a 2 inch piece of steel, then transfered it to the lathe to drill out the middle and cut some relief into the two ends. Casehardening was an interesting experiment, I had never done it before. Used Kasenit, this black powder stuff that comes in a can. You heat the steel red hot, roll it in the powder, then heat it again before quenching in cold water. It puts an almost glass hard case on mild steel, neat stuff.
