I want to add some wheel weights to my Ingersoll 4020, but the cost of the ones for them is kind of expensive. I already have a set of plastic Sears Craftsman 55 lb. weights, so I made a set of wheel adapters for them to fit the 16 inch wheels on the Ingersoll.
I used some 1/4 inch thick by 1 1/2 wide bar stock to make my adapters. I cut 2 pieces off 13 inches long to fit in the Ingersoll wheels, then I marked them for the mounting holes in the wheel and for the mounting holes in the wheel weight.
then I drilled out holes for 1/2 inch bolts using a step drill, added the bolts for the wheel weight and then bolted the adapter to the wheel using 2 inch carriage bolts.
then I bolted the wheel weight to the adapter. Works like a charm!
