    Subject: 36" center section design
    36" center section: With the direction from group members to build a 36" center section, please advise me if my thoughts are reasonable regarding the design. Cut the center section spars to 36". Lengthen the plywood laminated plates so they span from the end of the center spar back to the cabane strut attach points. The wing attachment brackets (flat stock) will be at the same geometry as in the Vi Kaplar drawing, however they will not be welded to the cabane strut weldment. A spacer will be needed to cleanly overlap the brackets on the wing. Fabricate the cabane strut attachment welment and locate it directly above the fuselage so the struts remain square to the fuselage and wing. So basically, fabricate the weldment as usual, without welding the flat stock wing bracket to the strut weldment... A person could also use something to the Grega plans however the traditional design calls for easy to use flat stock. I appreciate your thoughts and advice. Thanks, John ---------------------------------

    I need to know the two balance points on the aircraft.I suspect one is on the seat arm rest(for for and aft) and the other on the top of the wing for left and right. ________________________________ From: owner-pietenpol-list-server@

    Would recommend purchasing the 36" CC plans from Bill Rewey, his address wa= s listed a couple days ago on this list. Basically you are correct the only real difference is that the cabane fittings on the spars are separate from the wing attach fittings at the ends of the spars. Actually makes things easier I think. In my case, since I widened my fuselage 2" the top bolt holes for the cabane fittings mated with the top bolt holes of the wing attach fittings.

    Mike Looking at your wing with the bottom covered made me think of something. Di= d you glue (poly-tak) the fabric to the bottom of each rib, or is it best to wait till you rib stitch to pull the bottom fabric up to the undercambere= d ribs?

    John Sounds like you got it right. I am looking at one here in my shop built as you described. The only thing I did additionally, is to add 3 bottom plates under the fuel tank. Also, I have a 24" cut out.
