: 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.

Hi Simeon,
It's not a totally original idea, I've use a similar technique before that learned from a boatbuilder. Your jig blocks are not something I've seen before though, the technique I learned was to use a narrower plank beneath the 'real' plank. This strip is clamped to the edge of the plank to keep it raised a plank thickness while it is bevel planed using the previous fastened plank as a bevel guide.
Claim the jig blocks.

** This technique was only used for the planks at the turn of the bilge, mainly to make sure the caulking bevel is facing outward.**
