02/26/2001 04:44:14 PMChris,I can't really contribute much to the whole discussion of old wiretechnology, except to add one point. Many years ago my best friend ran apiano repair business, and I spent my late teenage years hanging out in hisshop learning the trade. Piano wire is softer and more flexible than the'music wire' stuff sold in hobby shops. It comes on rolls & we used a LOTof it to restring one piano! Obviously, though, it has a pretty hightensile strength, or it wouldn't withstand the loads put on it in a piano.I've been out of that business for a long time, but there are several ofwholesale piano repair supply houses still around if someone wanted to dosome research & experimenting.Cheers!Kip GardnerLaboratory Manager, ODUDept. of Ocean, Earth & Atmospheric Sciences4600 Elkhorn AvenueNorfolk, VA 23529(757)683-5654Bumper Sticker of the Week:"Don't Drink and Park - 'Accidents' Cause People"________________________________________________________________________________Date: Mon, 26 Feb 2001 17:29:15 -0500

I would be sure that the wire is obtainable in the lengths needed, but it's the ferrules which would not be readily found or made by an individual. The Kansas Aviation Museum here in Wichita is building a 1923 Laird Swallow and they had some ferrules made somewhere here and donated, but because the Swallow is not going to be airworthy I'm not sure if the ferrules are heat treated.

I suppose 1/2 inch higher and heavier wall would be all right, but this would further irritate the interference you mentioned. I have built six sets of controls and have about 90 hours on my first piet ('A' powered) and haven't experienced any kind of heavy control forces during G loading. I've had it in some rough air, but don't do any abrupt maneuvers. In fact, A pinkie is all that's needed on mine. It is very very easy to land; it behaves so well. I did not have the clearance problem you mentioned hitting the rudder bar or the rudder bar stand, but it does lightly hit the cutout in the front seat bulkhead on full left aileron, but I haven't needed nearly that much so far. I had an engineer fiend help me design my lift struts so I wouldn't have to use jury struts.

Ian Holland sent me the article on ferrules that was in the BPA letter in93. I can put that on my website with the other piet stuff so any one caneither read it from there or copy it. I have to thin it out a bit as the wayI have it now it is rather large. ( Trying to save on space so I can post asmuch as possible.) Give me a bit and I will have it up with the weight andbalance and rib tool and other stuff. I'll post when it's ready online.PS.... Got my spars together finally. Glad I'm over that hurdle. Now I justhave to finish the ribs.CarlPlease visit my website atwww.megsinet.net/skycarl-----Original Message-----
