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.

Regards.

Now you need to make some boxes! Nice looking jig. Have you got a flat top blade to give you a square profile for the slot?

Hi Jim, I will start the box making experience once I get mysaw up and running. I spoke with an electrician froend the morning, gave him the symptoms of the situation and unfortunately it sounds as though the windings in the motor have failed. Deep joy! lol.

Yes, I have several decent quality ip blades which produce flat bottomed kerfs. Thanks for reminding me though.

Hope all is well with you.
