"Universal box joint jig"
Posted: 25 Sep 2016, 15:35
Enforced periods of idleness away from the workshop aka holidays usually mean that my mind wanders onto some new project or other that I can do once I get home.
I've wanted to make box joints for a while now and have a requirement soon so that has been this holidays thought exercise.
My target spec has been to cope with timber from 10mm to 20mm thickness and with pins from 4 to 20mm
Most jigs I've seen only work for a fixed pin size which dictates the overall width of the joint to be = pin width *2*n where n is the number of pins. Rather like the simple dovetail jigs I find this too restrictive.
My jigs will be fully adjustable and I will use it with a dado set in the table saw but the design will be adaptable or use on a router table and the pin sizes will only be constrained but thne cutter size of which there are a good range in the 4 to 20 mm range both metric and imperial.
Firstly is there any interest in a full write up of this project and secondly any comments on the range of adjustments that I propose. Making it work over too large a range does make the design more complex and a jig to do big chunky joints might've bestdone as a second scaled up model hence my use of "universal" in the title.
Comments welcome.
