I am building an Arch davis design Penobscot 14 and I am at the point
to scarf plywood for the panels. I am hoping there is a jig design to
cut the scarfs on 1/4" plywood. I have seen jig for circular saws,
but I hoping there is a system to use with a laminate trimmer or a
router for cleaner cuts. Any help would be greatly appreciated.

Check the Gougeon Bros.

They offer an attachment for a circular saw.
