...and just what the fnork is a... ?

...'shotgun'???

I've derived from the various discussions that it has something to do with raising the pit cushion more quickly in order to return the ball sooner, and the 'A' series machines do not have it unless retrofitted...

But I don't see anything in the A2 service manual that I've got that refers to anything as a 'shotgun', nor do I see anything in the disgrams that suggest that the sweep/cushion linkages/timing are substiantally different from the 'A'.

Am I just being a tad dim here, or was this something that even the vaunted A2 did not have originally? [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img]

It is refered to as the rake latch assemble

Rake trip shaft, rake trip latch.

The latch trips open when a ball strikes the cushion allowing the rake to drop immediately. The rake falling is actually responsible for starting the cycle via a trigger switch wired to the cycle solenoid.

It's outlined on page 1-53 in my A-2 service manual under "Rake Trip Mechanism". I'm sure someone will tell you how it can retrofit.

On an A machine, the rake is lifted by link r87, page 61 of the parts manual for a-2's. Rake lowers and cushion lifts when rake cam follower arm comes off of high dwell of rake cam after machine starts to cycle.

Shotgun (96) on pg 59 of a-2 parts manual, replaces r87. On ball impact, shotgun will collapse onto itself (linkage pictures on pg 63 of a-2 parts book), allowing rake to drop and cushion to lift before the machine starts its cycle, so ball can get back quicker.

would a few pictures help?? I could send them if you want:
