Hi I am Rocken Mike I started forging my own knifes and blades last year and I have been having a great time doing it.
I have looked for power hammers and all are too big or too expensive so I checked out a few You Tube videos and built my own
It works better than I was hoping for. My biggest expense was the treated 6 X 6 post I used for construction it took 2 8' X 6" X 6" treated post.
Anybody with a little skill and a welder and a circular saw and a drill can build this cheep.
I got the bearing from a local motor repair shop and the pillow block bearings same place. The recoil spring is from a set of porch swing springs the rest was from my shop.
This was a simple build with easy to find parts with a budget in mind. I would recommend anchoring the base to the floor with the force of the hammer it wants to walk around a bit.
So I will share this pictures of it completed.
