For a while I though about installing auxiliary fuel tanks, so I listened for ideas at Sun 'n Fun. I met a RV-8 builder from Indiana (Evansville?) that decided to build a partially wetted wing, "like a Mooney." Sounded interesting, but it won't work for QB wing. Regarding plumbing to the tip tanks, consider using 1/2" diameter bushing (O.D.) and purchasing a 1/2" step drill and modified extensions (I think you'll need three or four) from Avery tools. If you can't find drill extension in the catalog, call ask for Bob Avery. He'll give you the part numbers and advise. Another approach would be to weld the drill bit to a slightly smaller rod.

An easier is to just make a drill extension from a steel rod of what ever length you need (less than $5) and a one piece set screw coupling from www.mscdirect.com you can find them in the lower left corner of this catalog page www.mscdirect.com/PDF/PDF03/3549.pdf or from www.mcmaster.com on this page of their catalog http://www.mcmaster.com/pdf/109/1029.pdf -- Chris Woodhouse 3147 SW 127th St. Oklahoma City, OK 73170 405-691-5206 chrisw@programmer.net N35 20.492' W97 34.342' "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -- Benjamin Franklin, 1759 Historical Review of Pennsylvania
