You could maybe try this take a board about 6'' by 1' long at one cut anotchbig enough to accomadate a drum sander that goes on the end of an electricdrill, then nail a small piece of wood strip perpendicular on the same endof the board as the notch. Now take your electric drill and fit it to theboard upside down with drum sander fitted to notch using wedgeunder drill to optain correct angle (pratice on scrap wood). Attach drill to board with hose clamps using the small piece ofwood that was attached to on end perpendicular hang this overplywood to be scarfed and slide back and forth using this as a guide!should scarf already glued joint, use the same aparatus to scarfplywood that is to be fitted setting angle to get max 16 to 1 if possible!----- Original Message -----________________________________________________________________________________

I never heard back after Steve's "wassup with the two-piece floor"comment. Can someone verify that this is not going to cause me greattrouble, as I have to do the same thing with the fuse sides. I amjoining the two floor sections at the white ash piece, so there'll be anice solid 3-way joint, and the sides will join at a 1 x 3/4 sprucepiece.Richard==="Lady, you want me to answer you if this old airplane is safe to fly?

Hmmm....I have to admit I'm somewhat skeptical that a scarf joint is necessary here.I've known of other Piets that had the sides at least butt-jointed behind anupright member, and one that was butt-jointed with a doubler on the inside(maybe one outside?) This one was built by an aeronautical engineer whom Iknow to be extremely cautious on everything else I have seen him deal with.I'd like to hear a little more discussion of the hows and whys of this. Ifthe scarf is important I'd be more educated by knowing why. Does anyoneelse have input?BTW I used a Baltic birch plywood for the sides and floor that is supposedto meet a marine spec. I used the Finland GL-2 stuff for all gussets. TheBaltic stuff came in 8*4 sheets. Not 4*8 -- the grain ran crossways on thefaces. I bought it for the sides and floor as it was of sufficient size.JMG-----Original Message-----

Richard, now that it is on I think I would go with the butt joint but withabout a 4-6" wide piece of plywood overlapping the joint the full width ofthe plane. It will be under the fabric so it won't show. I just startedinstalling my floor today. I have a large quantity of 1/8" birch in 5x5'sheets so I'm using two layers with each layer made of two pieces scarfedtogether with an 8:1 scharf. I also had to scharf the sides together.

Richard, I did mine as Steve explained....off the fuselage...then fit ,n glue. Of course make certain the scarf joint falls on a cross member...may even be stronger than straight ply??Don Hicks________________________________________________________________________________
