I missed out on the big Kerfmaker craze a few years back. I think I was spending the year dead for tax purposes or something. In any event, I have a bunch of projects in the shop that have doors with a grid detail and the Kerfmaker was the tool needed to accurately prepare the half lap joints. I am indebted to all of the fine example of Kerfmakers here on LJ and the great instructions on their used, especially Mafe (http://lumberjocks.com/mafe/blog/18170 & http://lumberjocks.com/projects/37513).
My Kerfmaker is made from 3/4” oak about 7” long. I went with a threaded insert and wing screw for the adjustment mechanism (photo 3). The fine adjustment screw is a 1/4” hex head screw. The jaws open to a bit over 4” so I can use it for the grid work or something as large as a face frame.
Now the obligatory use photos:
1. Cut and mill the strips to final size.
2. Measure the width of the strips using the Kerfmaker.
3. Cut the half lap joints on the strips.
4. Glue the half lap joints with a drop of glue and assemble.
5. Glue the finished grid to the plywood door panel.
