Pietenpol-List: rib wedges and one more question
Original Posted By: "Jack Phillips"
Hello once again, just getting ready to start my wing c-section soon. My firstquestion is do I install wedges between the rib and the spar, like the plans callfor? OR do i oversize the spar and taper it down to facilitate the ribs. Ido remember somthing awhile back about using plywood spacers, but can't seemto dig it up on the archives. Also, do I need to put the ribs with the extra supportson the rib root and on the outer portion of the center section? Thanksagain-Kyle[/list]Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Kyle,I used spruce wedges. A beveled spar would work fine, but is adding aconsiderable amount of weight for no benefit (in between the ribs).You need the ribs with extra support at the root and tip to withstand thetension of the fabric, which can exert an incredible amount of force.Jack PhillipsNX899JPSmith Mountain Lake, Virginia-----Original Message-----

I am going to make my spars out of 1" x 4-3/4" and then router out to make it lighter.I have heard of the spars being made of 3/4" by 4-3/4" and then no router.The cost for the fir is about the same but I think the 1" spar will be alittle stronger.Scott--------ScottRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 5 Oct 2011 17:54:17 +0000 (UTC)
