Hello,

Before I order a Trapper plan set, was wondering if anyone on the forum
has used Bead & Cove joints on these plans?

Thanks

You mean building it as a wood strip hull in the traditional manner or make the plywood flat panels out of strips of wood?

thanks for the response Matt ...

I was thinking about using a bit & cove on all the joints,
helping with fit up and the butt joints ...

I think he's referring to the method of strip building where the strips are made concave and convex alternately on each edge so that they fit together more smoothly. I think I've read about this on this forum.

Yup, was thinking of beading & coving the ply edges of the parts
before the fit-up and tie

oh. Interesting idea.

But keep in mind with stitch and glue building, precise joints are not required.

Bead and Cove is only used in constructions where the sections contact each other directly (such as stip plank building). In stitch and glue construction the sections don't meet, in fact it is important that they don't (http://www.jemwatercraft.com/forum/viewtopic.php?f=7&t=33), so bead and cove is pointless. :)

On power boats or large sail boats, hard spots (wood on wood contact) are not a good idea. Not an issue on paddle craft. The spacer idea helps tame unrulely plywood. But it is an option, not requirement.

there are plenty of strip built canoe and kayaks out there, why not mix the 2 techniques?

frog, good to "think outside the box" but with stich & glue your talking hard chines (angles) so bead and cove application would be difficult to say the least.
