In Response To: Material: Laminated ply & WRC? (Darren)

: Hi,

: I have some western red cedar strips, around 40mm x 3.5mm (1.5" x
: 1/8" I think that is). Some I have ripped down to 15mm wide strips
: for a kayak, but it's time consuming and they're too thin to bead &
: cove.

: So for some of the remainder I was hoping to use them on a couple of S&G
: designs - being able to utilise the wider strips to form the panel shapes.
: My initial idea is to trace out the panel shapes on ply as per normal, but
: use .8mm - 1mm thick ply and epoxy the strips onto this to make a
: composite around 5mm thick. After sanding, the panels would be around 4mm,
: the standard for most S&G designs.

: A little heavier due to the epoxy (or I could use yellow glue which may save
: weight?) but I assume the composite panels would still be pliable enough
: to bend into shape. I wouldn't be doing and "highly tortured"
: shapes - one in mind is the Kaholo SUP by CLC.

: Any thoughts on this as a way to use the strips? Or should I do similar but
: just edge-glue them flat? Or give up on the idea as too hard or too heavy?

: Interested in the thoughts of others...

: Thanks,

There is no requirement that the strips have to be bead and cove, many of us use a rolling bevel instead, fits the strips so the edges fit snug.

Strips aren't epoxied together, are glued with carpenter's glue.

Those strips are pretty thin, will take some playing but should be able to make them work for a stripper, the forms might need to be closer together if there is any sagging between them with strips that thin. For most designs they'll need cut to narrower widths than an inch and a half to get any curvature, you don't have any extra thickness to play with to plane to shape so will need to use fairly narrow strips so not much is required.

1/8" is pretty thin for most S&G boats too and making panels out of strips would be wildly time consuming, specially to replace relatively inexpensive plywood.
