Richard,Not to worry. I think you can get out of this one relativly easily. Thisis what I'm thinking:turn your fuse over.Temporarily position a wooden brace underneath the edge of the plywood to bescarfed to prevent any flexing.Protect the longerons by wrapping them with a thin piece of Aluminum andtaped in place. (protecting the longerons is going to be very important)Begin your scarf joint by marking a pencil line back from the edge. Youmay consider just a 12-1 here and make it 3 inches.Remove most of the material with a circular sander, or a hand plane. Finishthe detail cut with a very sharp low profile hand plane.BTW plywood is nice to scarf because the layers of wood are a greatindicator of how straight your joint is.Prepare your rear piece with an opposing scarf. Fit and glue in place allat once. Make sure that your scarf joint is well wetted with glue. Clampit by covering the joint in wax paper and nail or better yet screw throughthe joint in 3-4 places to tighten the joint until dry. If you use epoxy,clean up any squeezeout after the epoxy gets to the green stage.Once you are done you should be as good as new. Scarf the side panels inthe same way, (but before you attach them--Like I need to say that.) butlocate the joints in the forward end of the fuse box under a upright.Hope that helps,Steve EldredgeIT ServicesBrigham Young University> -----Original Message-----> Richard DeCosta> Sent: Wednesday, July 07, 1999 8:46 AM> To: Pietenpol Discussion> Subject: RE: two-piece floor>>> Any suggesions for scarf-joining the two pieces now that one> of them is> firmly glued to the fuselage?
