Subject: Pietenpol-List: Design questionPieters,My question pertains to the " 3 piece wing supplement" sheet for the Piet plans drawn by V J Kapler 1978, revised by Dick G Cason 1982. On the fitting forthe spar end it shows and directs that a weld be made on the top side of the long angular piece. Question: Why would it not be better to weld this verticalstrap piece to the lower edge thereby having the angular strap and the vertical strap on the same flat surface??? As I'm fabing these parts now I wouldsure appreciate some feed back on this one.Corky in his La. shop very dirty, grimy, sootie and all those things that make Piet building so much fun.________________________________________________________________________________

Corky,I was just picking my brain and seem to remember that part, cause it was veryconfusing to me. Below the angled steel strap (towards the bottom of the spar)is another piece of plywood. Like a triangle piece, and the same thickness asthe angled strap. The strap lays right along it, and the top surfaces of thestrap and the ply are at the same height. So when you weld the straps together,the top strap (verticle one) lays on the angled strap and continues downto lay on the plywood, of the same thickness. whew!Don't know if this makes sense, but the confusion to me was not realizing thatthere was another piece of ply ( a triangle) that was vertically below the angledstrap. whew,whew!walt evansNX140DL ----- Original Message -----

Subject: Re: Pietenpol-List: Design questionDon,Thanks for the input. Not to argue but to debate the point, I plan to use 1/16 th gussett plates on the C/S spar and 1/8 on the match ing wing spar withenough bend on the wing fittings to overlap the C/S fittings which will have abushing welded in.My reasoning was to eliminate that overlaping steel and merely cut the vertical strap much shorter and weld to the lower side of strap fitting. That'sthe way I'll probably do it but thanks for your input. Corky in La with NX311 on the gear.________________________________________________________________________________
