How to cut finger joints in plywood,kinetic wood wall sculpture,plans for wooden deck furniture - For Outdoors
The humble box joint is super strong, and simple to produce, provided you have the right jig for the job. The humble box joint (sometimes called a finger joint) is strong, attractive, and easy to cut using a sled or miter gauge on a tablesaw, outfitted with this simple jig. By cutting a series of fingers that interlock, you create a large amount of surface area for glue to adhere to, making for a super strong joint.
In order to be able to adjust your cut to perfection, I'd actually veer away from screwing the sub-fence to your sled or miter gauge, and opt for clamps instead. The key to executing the joint successfully, depends upon the precision with which your set your jig up.
This will allow you to move the sub-fence in minute amounts as you dial in for the perfect cut.
If the joint is loose when you dryfit it after cutting, chances are it will fail sometime in the near future, so be sure to take your time time when creating, and setting up the jig.
