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.
HEY,
QUIET GOOD I THINK, SIMPLE AND EFFICIENT , JUST ONE QUESTION
HOW TO YOU SECURE THE JIG ON THE EDGE OF THE TWO UPSTANDING
WOODBOARD… CLAMPS OR ONE SIDE OF THE JIG IS SLIDING ON SLOTS
TOWARDS THE OPPOSITE ONE ???? GOOD ONE ANYWAY. GAEL
It can be clamped to a standard cheap-o woodworking table with an adjustable gutter in the middle. Clamp the jig to the table on only one of the movable pieces of the work top. The position the work pieces against the bottom of the cradle and fasten them by closing the gutter. Then clamp the other side of the jig to the table.
What can I say.. It’s what you get for not wanting to part with the $150 for a decent jig
I must say, I could not agree with you in 100%, but it’s just my IMHO, which could be wrong.
p.s. You have an awesome template . Where did you find it?
Thank you! To be honest, I haven’t had the opportunity to try the jig out, although I have built it. So for now it’s still based on a thought and I don’t know if it will actually work in pratice.
My WordPress theme is K2, but I have customized it to some extent.
super hard router bits are hard to find”-:
we always use hardened steel router bits coz they last very long-*,
high carbon stell router bits are hard but they are also very brittle ”
