I’ve never actually made any boxes with splined joinery so I thought it about time I give it a go, at least build a jig to make the process of cutting the splines easier.
I had a look on YouTube etc to look for ideas, the one I liked the most was the jig being offered commercially by MLCS. However I didn’t like the fact the MLCS jig only had a single mitre slot runner. I made mine with two runners, made from hardwood.
The jig is in the main, made from 12mm BB ply, with 12mm MRMDF for the facings. Overall dims 450mm x 300mm.
I also liked the fact the commercial jig had sliding jaws to hold the box while being cut, so I made a couple for mine. It can hold a box up to around 350mm or around 14” if needs be. The jaws slide on a T track which is surfaced mounted to the ply base structure and the 12 MDF brings it flush to the surface, no routing or dadoing required.
I also took the time to provide the jig with replaceable inserts when the blade eventually chews up the MDF. I utilised the method used by an LJ buddy, thanks Klaus (Kiefer). Cutting the meeting edges at 30dgrees holds the insert in place, without the need for fixings although I have the option to use a couple of scores should I need to.
A little Perspex panel reminds me to keep my soft bits away from the blade yet see what is going on. I haven’t used it yet, my table saw packed up today, something electrical and hopefully not expensive to resolve.
