Small inserts are a part of many woodworking projects, but a lot of people have trouble with them
because they can be very difficult to install perfectly vertical. This is the simple little jig
that I use. It's turned out to be very effective in getting things correct. Every time I've used
it previously it was with 1/4-20 inserts. For this project I added the 10-32 inserts feature.
I'll need this one more time for a pair of 1/4-20 inserts on the back of the miter fence.
Since this will be installed on the miter fence quite often I don't want to use just wood screws.
