scarfing, again!
Posted: Thu Sep 11, 2008 7:36 am
Hi, I'm planning to build a SOT in the summer next year and have decided on the sabalo. I have looked at the posts on here regarding scarfing and have two questions which I can't find answered.
I'm planning to scarf the plywood sheets first, then draw out the pieces "whole". This seems to be commonly used with other stitch and glue designs and whilst it does look more of a PITA I'm convinced it'll be worth it. Do the sabalo plans detail offsets for "all in one" pieces? Or is it half-and-half only?
Secondly, has anyone messed about with "stepped" lap scarfs? I've worked with thin ply a few times and have on occasion needed to thickness ply along an edge with a router by 1-2mm. Having done this, I'm thinking it would be easy enough to form a jig to make accurate steps in the scarfed edges rather than make a perfect gradient. In 3 ply I'd use four "steps" so the inner and outer faces would overlap plus the inner core would be stepped. I'm thinking it would be very nearly as strong as a perfect scarf joint but much easier to do and far quicker. Has anyone done this?
Many thanks for your time folks, this looks like a nice forum community you have here.
