Here’s a couple of parf tables I made using 18mm OSB. The larger one is the maximum size to fit inside my van and sits on a couple of trestles but then I didn’t have the Parf jig to cut the hole accurately. It’s big enough the work on a full size sheet when on site. The second is the largest I can fit to one side of my van leaving more room to carry tools. This one can also sit on a couple of trestles or a pair of workmates. This one was made using the Parf jig.
Since then I’ve made a couple of smaller ones that fit either side of my compound saw. This was made using the Parf jig but this time in a hexagonal format.
I also fitted a couple of Benchdog fences with flagstop.
