Methods to consider for installing the threaded insert are:
Use a 5/16” bolt and double nuts on a drill press. Cut the head off a 5/16” bolt and chuck it in a drill press. Then thread on two nuts and the insert so that it is flush with the end of the bolt. Tighten the two nuts on the insert so it won’t spin on the bolt. After the pilot hole is drilled in the stock, clamp your stock with a handscrew or a drill press vise and manually turn the drill press chuck to drive the insert into the stock. DO NOT TURN ON THE DRILL PRESS. The drill press will keep the insert square to the stock as it is threaded in. We also recommend using beeswax, screw lube, or even soap to lubricate the threads on the insert.
This process can also be done on a lathe using a three jaw chuck in the tailstock to manually feed the insert into the stock.
And finally, if you’re using acrylics for your handle, we have found that heating the insert before installing it makes it go in like a hot knife in butter.
