    Tightened up a few more things after this, but I was able to forge a tapered socket mandrel from a piece of 1.25” round in about 5 heats.

    Ran it hard for three days with no major malfunctions. The way I had the dies set up to be interchangeable isn't going to work. It also hit much harder with a bit less space between the dies, but I was out of adjustment range, so I added a block of steel under the bottom die plate. I'll eventually need to lengthen the push arm to make up the adjustment. The weld between the bottom die and die plate cracked a little, and the bolt between the hammer shaft and top dies showed some pretty good wear. Looks like for the short term I'll have to weld up the interchangeable die parts to something more permanent, or at least change how the dies interchange. No structural failures or damage.

    Nice! Looks like you got a pretty good hammer there. How much was your final cost?
    Looks like you could use some bracing, the main support looks like it’s moving around pretty good...

    Yeah, it's not near as wobbly once I tightened everything up. The bolts between the anvil and the main upright were loose in the video.

    Total cost, maybe $250 cash, and most of that was the motor. Labor, probably 40-50 hours. Had the advantage of a great scrap pile to work from.

    Labor-wise, it wasn't cheap. For me though, I had time, not money, so it worked out well.

    Nice!!!
    A good cheap build is awesome!
    I like building stuff, but for some reason it never really ends up being that much cheaper than just buying it would have been. Well other than the economy of buying things slowly.

    I’m in the process of building a vertical forge, and I found that buying a blower kit was actually cheaper than buying the the dang parts!

    The body has been cheaper, but it kinda blew me away about the blower kit...

    Update. Installed a stiffer spring on the spring pack, and lengthened the push arm. In this video I was forging some 3/8” square down a little further on the tail end of a blacksmith knife. Hammer was hitting so hard I had to slip the clutch a little. Was too smashy :)





    Here’s what I ended up with.

    Hey Jason, now that you’ve had a couple months to break it, how’s your hammer holding up?

    So far, so good. I had a couple of tack welds come loose, but nothing critical. I've used probably 15 hours so far, and it's been great! I have discovered that it likes fresh grease on the hammer guides every session.
