Thanks Paul,
The current kayak was hand planed and matched. My idea is to have a minimum glue line and save the time of the hand planing. So on my next kayak I will try oversized bead and cove cutters on centerline. The quarter round and ogee cutters are interesting food for thought.
Your board contributions are much appreciated

: If you are going with the idea of using larger-radius rounded-edges on your
: strips then why even bother with a full bead and cove?

: If you have ever seen a drop-leaf table you'll appreciate how the leaf and
: table are edged with mating, rounded edges. These are carried into a
: squred-off "shoulder" for the table tops, but the same cutters
: could be used for giving a rounded, mating, large-diameter profile to the
: edges of cedar strips.

: In the case of the usual bead and cove, the cross-section profile of the
: edges of the 1/4 inch strips shows they are semicircles. The diameter of
: these semicircles is 1/4 inch, and the cutter has a radius of 1/8th inch.
: If you used a cutter with a cutting edge that had twice the diameter (1/2
: inch) or a 1/4 inch radius, and aligned your strip so the cutter was NOT
: centered on the edge of the strip you could finish the edge so that it had
: a profile of only 1/4 of a circle. You could do this with a roundover bit.

: With careful alignment an ogee bit could provide the two matching 1/4's of a
: circle you would need for each side of the strip.

: The downside of using strips with such an assymetric edge is that you have to
: pick your best side of your strip when you mill it, as you won't be able
: to flip it over. And these strips are more suitable for simple hull
: curvatures. such as on a deck, or the hull of a canoe. You can install
: them so they make a nice bend "in", but they won't do as nice a
: bend "out". The bit pictured below has a bearing on it, which is
: not needed for our use. A similar bit without the bearing would be less
: money, so these are pretty inexpensive cutters. That is, IF you can make
: the shape work for you.

: And then again you could forget bead and cove, or any other milled edge, and
: just use square edged strips. These are fast to fit with a small plane.

: Just a thought or three
