The jigs are made from 60mm hardboard squares. Slots are cut 10mm from the edge, and are a jam fit on the strips - I filed the entry corners of the slots to avoid damaging the strips. The standoff blocks are 10mm which in my case is the thickness of two strips.

When held in the jigs, the new strip has a 5mm gap between it and the previous strip. This is because the blade on my plane doesn't go all the way to the edge, so sitting the strips flush wouldn't work.

I made one jig for each form/station, and that number seems to be fine for most of the job. A couple of extra ones would be good during the longer strips as I was swapping jigs from one end to the other to accommodate the tighter angles around the bow and stern.
