Ok - so it's not exactly Lego

So, I've been able to spend more time in the shop with the canoe, and it had been going extremely well up until this week.

The wood I am using is of extremely good quality and the work I put into the forms and strongback have made putting the first few strips on, very easy.
I have a bright basswood accent strip set in between some dark cedar. Once the finish is on, it should come up quite nicely.

This part of the caone is relatively flat, so the strips went on very quickly. Once the first strip is on (the bottom most one in this picture) and perfectly level, it is like putting siding on. A bead of glue in the cove, center the strip on the boat and tack it in to the forms with a finishing nail (just to hold it in place while the glue dries).
But as you get to the "curvy bits", getting the strips to stay snug to the form becomes a little more difficult.

After laying a couple of stips each side, I came back to the shop the next day to see that the boards had come away from the form (despite me securing them with bungee cords while the glue dried). Apparently, this is not uncommon and probably could be avoided if one used narrow strips.

You can see that the form (well used now and is probably having trouble keeping the brad nail from moving around) is about almost a quarter inch from the strip - and this would get progressively worse.

So, off to the web to find some solutions. Al had told me to use a clamping system with wedges that would force the boards into place.
This is the best solution and some forums have also said using a heat gun on the strip before placing it in, leaves it a bit more pliable.
I boiled some water and saturated the wood to get a little more give in it before putting the clamps on. Seems to have worked.

This is going to be slow going for the next few days, but it should work. There is going to be plenty of sanding and "improvisational" carpentry before the fiberglass goes on.
There are systems that allow you to create a cedar strip using only clamps. This way you don't get the small nail holes in the wood. But, I'm guessing that those are a little more advanced than what I'm ready for right now.
