Sometimes it’s nice to be able to test what effect adding weight will have to a crankshaft balance. Since modern balancers also read cross planes, the placement can sometimes get tricky. This is especially true if the opposite side is close to the edge of the counterweight to begin with. In this picture I’m out of the size slug I needed to finish this crank, so I used this mock weight to allow me to rough it in close until the slug shows up tomorrow. I have a few different sizes and weights. Just drilled and tapped holes to use a jack screw to hold them in place. You can also change the radius to have more or less effect to hit your goal.
