I have a 1 horse motor 3450 rpm ( I am going to get a 1750hp one soon). My problem is the hammer gets stuck when the pulley gets too the up on the hammer. I’m wondering if I need a larger pulley or if it is just the resting position of the hammer. Am I way off. I’m aiming for about 2” at resting position. The tax weld broke on the shaft but would be at 2” if welded in picture
