Tony, Have just got back from skiing to be able to lay hands on my C of G data: I adjusted my C of G to be at 59" AOD and that allows any combination of pilot wt 120 to 400lbs/ Fuel 0 to 110 lbs/ baggage 0 to 80 lbs to give C o G within the 58 - 62.5" range. The precise calculations will depend on your empty wt ( that is a heavy pilot will not shift the C o G so far in a heavy plane). It means that I never have to do any calculations of wt & balance and do not risk flying out of safe balance range. So I would suggest 59" is an ideal figure to aim at, and would be interested to hear any contrary views.

If the first squeeze is correct, the second squeeze shouldnt disturb the consequences of the first, should it?? Tony - I'd very much hesitate to do anything outside the recommended practice. The security of the sleeve depends on the ductile copper flowing into the surface of the cable. The thing with copper is that it work-hardens, which is one of the reasons that the Nicopress people require that the 3 crimps using their tool be done in a specific order. If you re-work an already-worked piece of copper, you could be cracking it because it's no longer as ductile. Or, you could be loosening the grip of the sleeve by trying to push the copper at 90 degrees to the first compression. If you're using one of the screw-down tools that compresses right across the sleeve, I'd suggest that you be happy with the result after the first full closure, and not try to fiddle with it. There's some very good stuff about all aspects of terminating cables in a recent (Dec 2013) Kitplanes article.

I only vaguely remember the 3 crimps. I have a big squeezer, like a set of bolt cutters. It has about 5 positions, so you choose the one you want, position a little out each side as it is nominally shorter than the nicopress, hold the cable tight, and squeeze. The issue I have is that we are squeezing things into a circle, and one could think that you wouldnt be disturbing anything if you squeezed the small amount of Nicopress that exudes out the jaws of your tool, back into the circle. The other portions of the circumference shouldnt be unduly pressured, as they are already compressed to the inner diameter. I just struggle with the logic. Still, I have a test tool, and they fit correctly now that they have been squeezed, so they are correct. Ironic that there is a small link in the tailwheel setup that has a double nicopress on each end of a 5 link. Dont know why that is, considering by rights you shouldnt need a second nicopress. Im about to go off and have a look at the link you gave me, and cross my fingers that it works down under, or that I am not a subscriber. Thanks for digging it out anyway. I think I may have a written reference here at home somewhere that talks about these things, but on first look I couldnt find it, so that is why I asked the list, for that collective wisdom. Thanks again.
