AF timer and the fire signal cam

[Daniel]

I recently bought an 1978-vintage AF timer with what I believe was the standard setup of cams: an 8 seconds on/4 seconds off attack cam and a fire cam with five cycles of the same attack duration. What I would like to do is either replace or cut the fire cam for a 12 second on/8 second off fire signal repeated three times. Does anyone have such a cam available? If not, what is the best way to alter the cam?

Your best bet is to somehow make one yourself. Custom AF Timer cams aren't really for sale anywhere.

Use a Dremel or similar tool and cut one yourself. Trace out the lines you wish to cut and cut the lines.
