Elmer's glue of course - correct? :)Seriously, Mike has posted this drawing a number of times over the years, and it strikes me as a very sensible solution from someone who knows.Kip GardnerOn Jan 10, 2012, at 9:07 AM, Cuy, Michael D.

The bible (book of 1932, vs. 53) recommends a little fillet. Is it simply notnecessary? Are the "full sections" (center and spar attach points) made by gluing in fillerblocks?The drawing shows the spar being quartersawn. Is that preferred or necessary?If so, do the glued on parts need to be as well? As flatsawn wood expands andcontracts at a different rate than quartersawn wood, wondering if the pieceswere much different if it would stress the glue joint. I do know that this isthe reason dowel joints predictably fail (in addition to cross grain problems,dowels themselves don't stay round as they expand and contract with moisturevariances).

That's a funny thing about spar material.Currently, Aircraft Spruce lists the same price per lineal foot for 1" x 4 3/4"as for 3/4" x 4 3/4". The price for 1/2" x 4 3/4" spar material is only 20% less(for only half the material), and you will need to also buy some capstripmaterial to go with the 1/2" web. So the built-up spar will probably be more expensiveoverall.I recall not too long ago looking at the same comparison, and at that time, theprice for 1/2" and 3/4" were equal, but the 1" spar material was a bit more expensive.Wicks has a very similar pricing structure as Aircraft Spruce for theirspar material.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Tue, 10 Jan 2012 11:42:30 -0800 (PST)
