Gary,Thanks for going out of your way. Only 18 Ozs? That seems pretty light. I will check the metal weights and try to guestimate the weight of the fittings.Ray ----- Original Message -----

Subject: Pietenpol-List: turtledeck bracing Can you think of a reason the bracing is in an oval pattern? I would guess if they were straight across it would help even out the load.I can't Jack, it was just the way Frank Pavliga advised me on installing some 'insurance' supports mid-span the bulkhead-typestringer supports you've already got in there. I like your idea of having so many stringers-it really gives an elegant look.I don't think the plans show enough stringers so I added a few of my own that number close to 10 or 11.[cid:image001.jpg(at)01CAB3C6.1894C560] I was considering using 1/8" ply about =BE" high. Finished the back cap and belt slots last night.Thanks,JackDSMExcellent looking work Jack. One thing that was suggested to me by Frank Pavliga you might consideris using some leftover capstrip material to stabilize the stringers one to another as this sketch showed.This helps prevent the fabric tension as you tighten from distorting the stringers and bowing them.Mike C.________________________________________________________________________________

Gary,If I made these 22" struts (front/center) from metal, they would weigh 22+ ounces without the ends. How did you decide on the thickness and shape for the struts? Why did you chose Hickory versus, say ash? Did you laminate because you needed to get to a certain thickness, or for strength? There is a source for hickory and ash that has 2" (8/4) material in Chico, I think. I got some 1" ash for 2.37 per board foot.Are your "flying struts" (the long struts) also hickory? What shape?Thanks,Ray Krause.P.S. The aerostream tubing is very expensive, about $56.00 per front strut ($28.00/ft and .7593 lbs/ft). Wicks has it for $17.00/ft right now. I am not sure of its quality. None of the aerotubing matches the recommended sizes on the plans (1.5 X .75 and 2" X 1"). ----- Original Message -----
