Has anyone tried a "puzzle joint" rather than a traditional scarf joint? clcboats out of MD offers plywood with a puzzle joint they claim meets the 8:1 scarf joint standard.

please explain your first choice of cutting for a scarf joint. I'm not sure I get it.

Tom, I did my scarfs for my snowgoose with the table saw. You basically tilt the blade an appropriate angle for an 8:1 and run the sheet through the saw standing on its 4' edge, which requires a modified fence to hold it plumb when cutting. The sheet of plywood needs a straight board clamped to it to keep the plywood from falling into the blade once cut. I build the jig and cut all my scarfs in a morning by myself.
I have pics somewhere, I'll post if I can.
Thanks

I can't find my pics Tom, I have the final product that shows how perfect they were, but not the jig. If you are interested it is easy to describe in detail.Thanks
Sheet in saw (note I'm doing this my myself, it would be really easy with help).

Tod,
If you had help, would they be leaning out the upstairs window feeding it through? I don't doubt it worked, but honestly, even seeing the pictures, I don't think I'd go that route...maybe I'm just a chicken...or maybe I know I'm accident prone, and Murphy's Law would definately take over that operation if I were in charge.

Tod,
I'll offer a suggestion which may help ease the concerns of this being a safe endeavor. Modifying the support board which runs along the top edge of the fence as shown in my drawing, whould also help in keeping the sheet vertical during the cutting process.
