A hand tapper or just use a guide block. For wwing a hand tapping rig is overkill. To make a guide block just bore a guide hole on the drill press to to major diameter of the insert. hardwood should last at least a few projects.

Hard woods like maple or cherry take machine screw threads really well with no insert.

I do hundreds of brass knife type threaded insert a year. The jig in the images worked great with a cordless drill. Now I set up a reversible tapping head on a drill press. Due to triple price increases in brass inserts I use zinc inserts on several products. Yes, they will work on hardwood if you drill a larger hole. I eyeball 90 degrees with a cordless drill and let the flare top straighten it out if they go in crooked. Also, backing it out and drilling again straightens it out. I put a dab of epoxy in the threads.

Ask a woodworker to "make your bed" and he/she makes a bed.
