What would we do without that 500 billion dollar trade deficit. I bought a pair from Stein (also imported) which doesn't require a shaving kit full of dies, but does cost a few extra bucks. Convenience worth the money. See their tools page.

It works great for crimping some large wire gauges - 8 tons of force, hex crimp, etc. However, the dies that are supplied with it are completely marked incorrectly - at least for the type of terminals we typically use in aviation. The range is on the small size in reality and most of the dies are not usable. It will, however, crimp standard #4, #6 and #8AWG wire terminals using the dies marked "00" (biggest), "0", and "2" respectfully. It might do #10, but I didn't have any around to try. So, it's cheap..and it works...just don't expect a correct die set.

These occasionally go on sale at HF for under $50, and with a 20% off coupon on top of that, for <$40 a very nice tool that crimps from AWG-12 to 00 cables. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=66150 ________________________________ Message 3 _____________________________________ Time: 10:10:05 AM PST US From: Etienne Phillips Subject: Re: AeroElectric-List: Re: EFIS Articles (Mis quoted Link) Indeed. I wonder if it's coincidence that Dynon have since started using GPS augmentation to help with lost airspeed data? Either way, it's good for everyone to have a clear, unbiased comparison.

One thought was that you could use one half of a bridge rectifier diode with fast-on tabs to provide a simple way to provide dual inputs and handle the diode backfeed protection. The only problem with that is the forward voltage drop can be significant. I noticed it is 1.7V on a Radio Shack piece that I looked at. I called B&C and they did not know (?) what the forward voltage drop was on their product (I am guessing it might be the same). I like the simplicity of the bridge if the drop wasn't so significant. Do you tend to prefer axial diodes or some other solution?
