If I remember right, my attempts at threading piano wire were futile. It istoo hard and would most like ruin the die or the tool bit.Chris Bobka-----Original Message-----

You also wouldn't want to, since cut (rather than rolled) threads are astress point.Gene-----Original Message-----

Just searching around on rec.crafts.metalworking shows a TON of messages onrolled/cut threads. Some pertain to aviation. Further along on rec.aviation.homebuilt I found a link towww.deaircraft.com who have draganti-drag wires and tail brace wires.Take a look Ray,( but they are trying to make a living. ) They have lots ofwing parts that someone could use on a Piet. Aluminum extruded spars! Inever imagined that. I thought aluminum spars were built up, riveted dealslike a RV spar.As far as my progress goes, it's slow. I'm lucky to get 4-5 hours a week onit. I built my rib jig twice, and poked around trying to come up with aquick way to cut rib pieces. Cutting by hand was not my idea of fun, so Ipicked up a tablesaw book at the library and built a sliding table jig. Itwas easy to make. Basically get two strips of hardwood to fit the mitreslots, and screw a good flat board on top. I used 3/4" MDF. Then screwed a3/4 x 3/4 x 15 arm that pivots at one end near the blade. I had cut amaster of all the rib pieces, so I place the master against the blade, pivotthe arm to meet it, and pin the arm down at the other end. Then clamp ablock at the end of the rib piece, and cut away!! For each part I cut 30 orso pieces from the long strips then re-cut them to the exact angle/lengthsize. I cut about 1/3 of all rib pieces in no time at all !! I have my ribpieces laid out so one end is 90degrees and the other has an angle. Makesit easier than multi angles on each piece. I stack them in numbered tincans by the jig. This is the way to go! Kent HallstenAlmost done cutting rib pieces-----Original Message-----
