Hi,
I am an amateur blacksmith and was doing some research on power hammers as I would like to build my own. My shop is not going to have electricity so I have a design to make it foot powered with a large flywheel. Although, many of the commercial hammers I have seen have a triangular arm with a spring in the middle.(as pictured below) The top is connected to the flywheel and the bottom to to the hammer. I am wondering what the advantage is to this as opposed to a straight arm with two pivots.
Thank you,
B
