Today was the day to install threaded inserts.
First I locate the insert on the neck with an awl, mark the location with a sharpie, and drill on the drill press.
The Irwin clamp keeps the neck from rocking on the frets during the process.
Next I tap the hole, and using dedicated sacrificial inserts I locate and drill center holes that allow the mounting bolts to penetrate past the insert and into the neck.
I modified a cheap screwdriver to use as a driver for the inserts.
Finally, I install the insert, lock it in place with thin CA, chase the threads, and tap the wood below.
Once it's time to attach the neck, the locating pins assist with any fine-tuning of the mounting holes in the body that may be required.
