Regarding "reversing" mag direction, on Bendix mags the cam the points ride on is removable, allowing a person to use the same basic rotor for either direction. In fact, this is a favorite ploy of mechanic examiners: reverse the cam, hand the mag to a prospective mechanic and ask him to troubleshoot why it won't work. You'd be surprised (and dismayed) at the number of people who just can't grasp the idea of comparing what they have in their hand with what is described in the manual. I don't know of any easy way to adjust a Slick (Unison) mag internally for rotation. I think the "E" gap, or the point of null, is pretty much fixed. As for the timing box, I have the schematic for it around here somewhere. Used to require students to build their own. Taught them some about electronics, soldering, and just how the darned thing works. A more modern unit can be purchased from most supply houses for about $50.00 'merican, and is a snap to use. It is an excellent investment for anyone contemplating maintaining their own piece of flying history, or any aircraft for that matter.Ed________________________________________________________________________________

I agree. Just a reminder to all, there is a public upload directory atthe site, here: http://www.AirCamper.org/Upload.cfmFeel free to use it for things like this.Richard--- David Swagler wrote:> > Ed,> > That is a schematic that needs to be at at Richard's> aircamper site.

Our students build a kit timing light. If anyone is interested, I'll get thedetails of where we get it and how much it costs.Ed0248(at)aol.com wrote:> Regarding "reversing" mag direction, on Bendix mags the cam the points ride> on is removable, allowing a person to use the same basic rotor for either> direction.
