: I've built several s&g kayaks, which have been very successful, structurally
: & design. However I only attempted scarfing ply on the first. A couple
: of the scarfs failed during building, so I backed them up with a ply strip
: epoxied across the inside of the join, which is what I did with subsequent
: boats. Not pretty, but strong.
: Is scarfing such thin ply practical, and does anyone have any ideas for
: prettier scarfless joints?

: The other problem is that when I cut ply with a power jigsaw and fine toothed
: blade, the surfaces are damaged along the cut with lifted fibres/splinters
: which have to be sanded off.
: I'd appreciate any ideas for clean cuts on ply.

: My first visit to this excellent site, can't understand why it took me so
: long.

I have never scarfed that thin either, but I might try stacking 4 deep or more and use the Vaclav scarfing jig. Careful of the orintation of pieces!

On cutting them out, I have not tried this but I expect to have one of the little 3" battery powered circular saws to cut out my next S&G. I also cut two panels at once. The upstroke on the jigsaw always tears no matter how careful you are.
