My first table saw jig (well in the form of a sled)
Just interpreted some examples on the internet (youtube) and made it with the left-overs from the table-saw build.
The material is HDF or (the grey colour stands for exterior use, so it handles moister a bit better and is harder, also less flexible). The rest is re-used materials.
When making box-joints I have to put a piece of tape (or two) on the guiding block, and remove tape when making wooden hinges.

Of course there’s a video: (sorry for the bit of loud music, that went…well a bit wrong)

’’Just…!’’ It looks great! If I’m not in woodworking I would say it’s some musical automatic maschine. I hope some nice boxes will come out of it.

Tidyest jig I’ve seen in a long time – Majuvla is right – it’s a hurdy gurdy and accordians love child ;o)

I tried making the jig. Once I got it built, I ran some test cuts. I found not a single run did any of my joints fit properly. Everything is square, flush, straight, etc. The pin is the same thickness as the blade width. The dominoes are all equal sized and 1/4” thick. I’m not sure what I am doing wrong but my joints are completely screwed up. Some are moderately tight but still have gaps in them. The stock is held down with a bar brace as is shown here. The fence on the carriage is aligned with a square and sits flush with the saw kerf.

Any ideas on how I could possibly have messed this up other than is is not done on a lathe. I have never worked on flat work and thought I would try some boxes with all the leftovers I have.

I have spent three days trying to make the jig and fine tune it.
