I have several sets of airplane plans at home, and one set for the Smith Miniplane uses...(to attach the top wing to the lower wing) anAn46-26 eyebolt in the lower rear wing mount, and a 3/8 cut thread homemade nut, pinned, and welded into the wing strut.I have been looking into this system for my ace, except that the cut thread nut, would be replaced by a formed thread coupling nut, welded into the wing strut. Then to avoid the welding scale, I would either use white lead, or just scerw a beez wax coated bolt into the coupling nut and weld the nut fast into the strut.The bolt to plug the thread hole, and the bezz wax to produce a smoke gas schield to keep oxygen away from the weld.About the an4626 bolt, wicks catalog says that this bolt is strong to 125000psi, and it costs only 14.00 or so each.ocb>From: Ian Holland >Reply-To: Pietenpol Discussion >To: Pietenpol Discussion >Subject: Adjustable lift strut attachments>Date: Wed, 28 Apr 1999 10:49:48 -0700>>The machine is on the gear and I have been following the discussion on>the 3/4 X 2 1/2 inch lift strut with great interest.
