1708 mat for stringers

Thanks, really good info. I was plannig on going with the foam or 5200. As he bedding. That would give me as long as I needed. Unless you think the woody mix is much better

The foam is probably just as good but I would tab with the full 4 layers if you go that route. The PB is a mix of cabosil and resin. It isn't the wood flour.

Some people get all frothy mouthed about using 5200 versus foam versus PB for bedding. I read an awful lot and personally liked the PB bedding the most. They all have positives.

4 layers of biax is about 1/8" thick so you may have 1/4" of glass supporting your stringer. I figured if I'm buying high dollar 3/4" marine ply, I wanted the full strength transfer throughout my hull.

Here are a couple pics, one is before bedding and the other shows a test fit of the cap but you can see the layers of tabbing from the ink I marked the glass to cut the widths. See how nice that radius is....pretty proud of that

that is some nice craftsmanship you did right there. What did you use to apply the PB under and on the edges of the stringers?

Big zip lock bags with some duct tape on one edge then cut the corner off to make it like a pastry bag to squeeze out like icing. Smoothed the radius with plastic spoons.

makes sense. thanks. This is off topic for this thread but how many sheets of ply did you use for your transom?

[tartuffe]

2 sheets of 3/4" marine grade ply, birch. You just can't get two transom cut-outs out of 1 sheet. Very close but not quite possible.
