Should be able to use either. For my use I want some good wood since it has the stress on it.funbun said:Is it necessary to have clear lumber for gunnels and hard chine logs? Is there a disadvantage to use simple 1x whiteboard found at Home Depot or Lowes?
Is that for the interior gunnel only? Could it be use for the exterior gunnel?Kayak Jack said:I use wooden spaces about 1/2" thick every few inches, then glue on a strip of 1/8" plywood. I have it about 3" wide at the center of the boat, and taper off to a bit less than 2" wide near the stem ends. This is about the same weight as a solid board - maybe a teensy weensy bit lighter - and is stronger, allows draining the boat when leaned up on edge, and provides tie down holes for camp gear.
Also, I seem to have a lot of plywood.
I would guess so. There would be a splice issue to deal with for plywood. I did make a test board of five strips stacked and glued. A splice failed when I applied bending pressure. Could have been inadequate glue. It was a scarf joint of sort, really a butt joint with 45 deg. ends.funbun said:Yeah, this leads me to ask can you laminate 5.2 mm Lauan plywood to serve as gunnels?
Jimmy W said:Home Depot sells molding that comes in long clear lengths. At least they did when I built my pirogue.
Home Depot has the strips up to 18 feet at our local store and that is all I used on the boats I make. Nice solid pieces and are pine which conforms to the shape of the boats. They are 1/4 by 1 1/2 inches and 18 feet long.Jimmy W said:Home Depot sells molding that comes in long clear lengths. At least they did when I built my pirogue.
