Default Adel clamp for wires

Dave:

I just finished up wiring my Pmags.

I put on two sleeves of heat shrink tubing around the wires. This increased the diameter sufficiently enough for the adel clamp to securely hold the bundle.

Must you be such a wet blanket? If you want tried and true, buy a spam-can. The mere fact that you are flying an RV-9 and not a C-152 tells me that this is not the case. Why not a Curtiss Jenny or a Sopwith Camel? Those were perfectly good planes - why mess with a good thing?

If you can build a better ignition system - go for it. Until then, please don't tell others that their choice is wrong. It is, after all, their choice. The magneto was once dangerously new and untested as well.

Long live EXPERIMENTAL aviation....

I have to agree with you Greg.

John, c'mon man. Seriously, why do you constantly need to harp on others choices? You are a big contributor to this forum, and most of your posts are worth reading. Then you throw in stuff like this. Can't you just let it go? This thread isn't even about EI vs. Mags. Dave had a small problem, so he posted the problem seeking some advise, and you start an argument. It wasn't even a problem with the Pmag!

Whatever. Again, this is probably someplace that I should keep my mouth shut...

Next thing I know, you'll be telling me how horrible a person I am for putting an Egg E6 in my airplane. MY choice. We are not building airplanes for YOU.

An Egg in your airplane? What were you thinking? Don't you know that causes global warming, melting icecaps, and will starve 3.8 million children in Sumatra?

Like I said guys, technology should benefit man, not harm him. As long as these accessories continue to fail regularly, I will continue to trumpet the virtues of magnetos. Have a good day.

And that's fine - but you weren't trumpeting the virtues of anything - you were bashing another competing product in a childish and condescending manner. That was uncalled for. Mags fail too, ya know.

'Nuff said - back on topic, please....

Dave,

Thanks for posting this issue and thanks to the others with suggestions. I've just installed my Pmags and you guys have given me some good ideas on how to secure the wires.

Thanks again!

Default Try Ferrules

You can crimp or solder these hard-tips onto your wires to give the screw clamps something to bite on. Solder can cold-flow under the clamp and can cause the connection to loosen up over time. The other advice about strain relief and clamping is valid and a drop of loctite on the screw threads wouldn't hurt either.

The connector is from Phoenix Contact (or a clone). Have used a ton of it over the years. Good stuff. Mouser stocks the ferrules:

Phoenix Ferrules

You might also find something similar at HD/Lowes. They are commonnly used in control / panelboard wiring with screwclamp connectors.

Hope this helps.

Default 1 pea mag in a plane

[quote=gasman]Dave, solder all of the wire ends, then heat shrink back about 3/4" for support. Then make a bracket to come off of that allen screw in the photo and secure all of the wires to the bracket. The set screws could use a little lock tite. They will bite into the soldered (tinned) wires better that just the twisted group. This is not a good connection to use in an aircraft. But you will have to ask the "PEA" mag people why they did this?

Why not have one super smart polyelastic electronic plastic mag and one real magneto? When the one that is going to break, breaks, you just keep flying.
