Thread: Best procedure to 're-round' the pivot hole using brass sleeve insert?

1/4 drill bit? You (and your bit), might regret that! Here is what I generally do, if I do it at all. I pop a 1/8 aluminum pop rivet in the hole and tap out the mandrel, which is 1/16. Dermel drum sand the head and excess off. You then have a tight-fitting aluminum bushing with a 1/16 hole. The soft aluminum rivet conforms to the odd-shaped hole in the tang and is easily filed internally if it is not perfectly straight.
