We had run the X1-a quite a bit but it was just tacked together, shims and counter weight had not been installed, the ram guides not adjusted or well lubricated. The scale assembly drawing was made and the second hammer was corrected on assembly of the frame. It ran well but we had height adjustment problems. We corrected those then mounted the motor and tested the hammer. The first assembly of the X1-a brought to light a number of issues. The only major difference between our two hammers is the anvil construction.īoth demonstrate methods I published on our Junk Yard Hammer page. X1-a Trail Assembly and the Complete X1-b
