Anderson Timer question
Which part of the flat contact gets touched by the flapper first? The butt end or the ramp?

Ramp
The camshaft turns counterclockwise.

Re: Anderson Timer question
The flapper contacts the end of the segment first and then rides down the ramp.
(The cam turns counter-clockwise if you are standing in front of the car. The cam turns clockwise if you are sitting in the car.)

Re: Anderson Timer question
I agree. But that doesn't answer my question.
I am assuming that you are looking at the camshaft and flapper from the front of the engine to get the counter clockwise turn?

Re: Anderson Timer question
Like this? Keep in mind that this view is reversed from what we normally see.

Re: Anderson Timer question
All of my Model T life I have assumed that the flapper touches the ramp first, then "flaps" off the butt end to get ready for the next strike. That just seems more logical to me. Now, a project that I'm working on has me looking closely at the mechanics of the timer, and I thought "no way". After talking to several others their answer was - ramp first. So that is what brought up my question.
Thanks- Adam & Ron for your help.

Correct.
This is the 'normal' view of the Anderson flapper.
The flapper is a sliding, gliding contact rotor, unlike the roller type that have to spin at speed.
The flapper is a wipe contact, spring loaded.

Re: Anderson Timer question
It makes good sense. The abrupt end of the ramp is timed so that the flapper hits each segment at the proper time for the spark.

Re: Anderson Timer question
Ron- the camshaft does turn counter clockwise, as you stated, if viewed from the front.

Re: Anderson Timer question
You can fill the cup with axle grease, that will keep it lubed, and you won't need to check it for years...That is what I learned from those who service the T's at the Henry Ford. They service them once a year after about 5,000 miles, I am not sure what they do at that point , they could just put new ones in but I don't know for sure...I serviced mine 5 years ago and only drive about 200 miles a year, the grease does not drip out with heat...
