    Subject: AC tug
    It looks like my original post got lost in internet space... Does anyone know of/have experience with, or has anyone built an inexpensive aircraft tug to share detail or suggestions? Maturing shoulders and thorn rotator cuffs no longer lend themselves well to pulling the bird out of the hangar, something that was "piece a'cake" some years ago :) Rumen

Greg Richter and I had some lengthy discussions on this about 17 years back after I reviewed his "Wiring for Smart People" publication. https://tinyurl.com/qxvr6nx I'm aware of no manufacturer that uses Teflon for general airframe wiring. Of perhaps 30000 feet of wire I have in inventory, I don't think there is a hundred feet of Teflon. Here's a copy of the Wire Bible which was updated on the website this morning. This is a searchable pdf file that will allow you to quickly identify about any wire product by specification. https://tinyurl.com/ydgacclw Having said that, Teflon is not 'evil'. If you got a heck of a deal on some I would not discourage it's use in avionics harnesses but it's kinda finicky to strip. https://tinyurl.com/bol9x2n Bob . . . Un impeachable logic: George Carlin asked, "If black boxes survive crashes, why don't they make the whole airplane out of that stuff?"

I had spotted a 'deal' on about 1K ft of P (IIRC, it was ID'd as M22759/9), but then found the same quantity of E (M22759/16) for about a penny more per foot. Not a big enough price delta for the hassle. Many thanks for the info; if I run across some P with a bigger price delta in the future, I may well add some to my 'inventory'. Charlie

    Many times you can find those used small garden riding mowers for sale cheap. Throw the defunct mower section away, and tape up the cracked seat cushion and you might have a winner.
