If you find yourself having to fill a counterweight hole when balancing, here’s a tip. Once your piece of metal is installed, drill and tap for a tapered crack repair plug, as a secondary retention procedure. This, along with the press fit, gives you absolute assurance that it won’t come out. This can be done with or without welding. Drilling and plug welding from the side is another thing I’ll do as well. It’s probably more to pacify the customer’s concern, as there are always stories out there of pieces coming out.
