Hi Dave,

I'm not sure if it's an original idea, but I haven't seen it anywhere else, and if nobody else claims it - I will..

The basis of the idea is that the tops of the strips are at 90 degrees to their faces, and that the blade of a plane is at 90 degrees to it's sides.

It follows then that if we run the side of the plane along an existing strip while holding the next strip parallel with the form where it will be mounted, then the bevel angle will transfer completely accurately to the new strip.

Apart from the very ends of the strips where they can't be supported by the jigs it seems to be working perfectly on my boat with no free-hand tweaking required.

I used 60mm squares of hardboard, slotted them on my tablesaw, and glued 10mm steps onto them. I made half of them the other way around to suit the other side / end of the boat, but it turns out that there are very few of the strips that required the jigs on the other side - only where the angle between the form and the hull was quite sharp.

The strip then slides into the slot, and there's a tight enough fit in the slots to gently hold the strips.

I also cut non-standoff slots on the opposite corner of the squares with the thought that I could use them to hold the strips while gluing, but that has turned out to be unnecessary.

A picture is worth a thousand words - in this picture the standoff block is facing us, sitting on the edge of the form.

I'm happy to post more pictures if required.

Simeon.

: Sorry if I missed it, but can you supply further details on its use.
