Darren, the jig is a tool sold by Brownells. The screw is held in a small v-block that centers it between the hardened rollers that guide your saw blade or file for cutting the slot.
Yes the files have safe edges for controlling the cutting action. I have two types of files. One has safe faces and only cut on the edges for cutting the bottom of a slot. The other has safe edges and cut on the faces for widening the sides of a slot. You can get them in various thicknesses as well.
Not going to charge myself labor though.
This is one of my back burner projects that has been sitting in the box since I bought it several years ago. Unfortunately it has a few more (very visible) exterior screw slots that have been marred up by using improper screwdrivers that I will need to deal with as well. It's apparently had a bit of a rough life since completing it's service with the Marines.
It just needs a little TLC that's all.
