My plans call for 2" water pipe which runs through the nose and aft ribs when building the wings. Not knowing better, I went to the local hardware store and asked for the price of two 10 foot long pieces of pipe. $175 was the price. Too much $ for a one time use item. I then asked the price for two 10 foot pieces of metal EMT conduit. Price was $40 for two. The 2" EMT is extremely stiff and straight. They are now slid into my wing jig, awaiting the wing components. Hopefully this information may save builders some cash.
Currently, my ribs are formed and lined, the main spar is fully drilled, deburred and dimpled where required, spar caps and end plates are match drilled to the spar and marked for position. Now working on the rear spars. It's a LOT of holes, guys - and there are a lot more to come when the wings get skinned.
In the meantime, I have read the posts about the dip in the skin just above the spar, and I am determined to prevent that on these wings. I also have to decide if and how I want to utilize the first two nose rib bays as aux fuel. If I do that, I think I'll make two custom nose ribs for each side.
