they have pivoting rubber pads on either end with screw holes; you ratchet them out and then twist them to fine tune the clamping pressure.

And this is the result...

Looks pretty handy, but could you have built a form on a piece of ply and used a series of c clamps?

This outer stem isn't laminated to the boat yet (there's a layer of polly between it and the boat), by this proccess it's a "perfect" fit. The bow one was laminated at the same time as the inner stem, and still required several hours of fitting. Things change, for several reasons including builders "skill", (this is her second stern outer stem). Besides when one of our installers showed me these "clamps" I just had to have some; any excuse to buy a tool...

Any way; here it is dressed, all cleaned up and back on the boat:

Gert, where you able to glue-up all at once? How did you keep the slats from sliding around. Just did uh. Again excellent results.

Chuck:
No, it's a 2 stepper. 10 layers the first day, 10 the next.
1st layer is pinned to the boat with 3 short brads, each layer after that was stapled at the extreme ends to the previous with upholstry staples; by layer 10 it's starting to want to come apart.
When it came off the boat on day 3 I ripped it to width on the table saw to get a square to face edge, then just planed it. It's (inboard) finished width is 2 7/8" which is 1/2" wider than plan (yes, we are deviating slightly here from Iain's drawings) And I think I just figured out where the shaft log concept comes in. O well.
