I made this puller when I was trying to get the wheels off the Cub jr, I was thinking I was never going to get them off. The piece of steel I was using was geting well hammered and I had used plenty of HEAT to, then had the idea of the spring steel,to hard to drill so had to make holes with cutting torch. When I tried again I found every time I hit it with the hammer the bolt would tighten a little eventualy the wheels came off and I have never used heat since.
