So relaxing, the idea of waiting for glue to cure. I think I am drawing on a lumberyard bench! well, maybe ‘lumberyard bench’ is too fancy a term. it’s dunnage.

You'll see anywhere from 6:1 to 12:1 depending on the scarfs application. I am in the process of gluing up some 12:1 scarfs for birdsmouth mast staves. The thought of scarfing plywood seems to produce a lot of anxiety for first-timers. All sorts of methods have been conceived to produce "perfect" tapers when, as you already know, it is very easy to do with a handplane and perfection is not necessary when using epoxy as an adhesive. I've tried scarfed planks, payson joints (butt joints sided with fiberglass tape set in epoxy), and butt blocks. I've had the best success with scarfs.

I used what CLC recommended in the manual and didn't even think to double check the math. I've often read that 8:1 is a good minimum slope and I think that's why I jumped to the erroneous conclusion about 8:1. I won't argue with CLC's success. If they like 6:1, it must work. Well, the joins are mostly cured now and look pretty good. You are absolutely right Mike. It is 6:1. I used what CLC recommended in the manual and didn’t even think to double check the math.

You have a 6:1 ratio, 1/4 x 6 = 6/4 or 1 1/2. Is the 8 a typo? Mike Bob,
