Re: Row Boat Motor Magnetos
Tom, thanks for the idea of the "Stops". That would work quite well.
I looked at a tractor magneto this morning, and there’s less than 90 degrees
rotation (spark advance) on the timer.
Regarding the "points less" timer, it sounds like you’re talking about
something similar to what Mr. Parrott showed, in the photo below.
That might be easier than points, but I’d have to figure out some
sort of tensioner for the timer that didn’t interfere.
Thanks!
P.S.- just thought of maybe putting a spring loaded ball bearing
in the mount behind the rotating timer, with detent holes in the
back side of the timer housing to match.
Wonder if that would work?
quote Tom Manley:
Well, here’s my two cents… Two pins stick out from the front plate. The whole barrel turns, controlled by a rod sticking up. You can mount points in the cavity, but the model T Ford timer method is a lot simpler: Put an isolated contact through the machined out part of the barrel, and a simple contact spring on the end of the rod. As the spring hits the contact, you make the circuit for a buzz coil.
Based on what I see, you can figure out how to tension the rotation of the barrel.
Wish I had a better drawing program on this computer.
