A finger joint is one of the strongest ways to connect two pieces of wood and it requires no screws or nails, only glue. It is very hard to accomplish without a jig specially created for this task, but they are expensive. So this is an attempt to design a DIY finger joint jig that’s as cheap and simple to build as possible. It requires a work table with a gutter in the middle and fixtures for the work piece, this is just an idea for a jig that will control the spacing of the fingers. If you know a thing or two about this kind of thing, I would really like it if you could tell me what you think, or even better; ways to improve it.
Here it are the plans: (download as pdf)
All white elements in the drawing are wood and so are the spacers as they are will have to be made to match the width of the router bit used. There are angle plates at the left side that serve as stops for the spacers and the cradle will be pushed against the spacers.
I have built it and some day, I hope very soon, I will have the time to try it out. If you give it a shot yourself, please tell me what you think.
EDIT: There is a thread over at Router Forums about this project.
