  • A1 2nd ball rake overtravel

    I saw an A1 machine that does not perform the rake cam overtravel getting ready for the 2nd ball. In fact, there was no cam follower on the outside rake cam. Is this something that is modified to work with automatic scoring? Is it an easy modification to do? Thanks.

      Howard;

      The reason for the overtravel on the model 'A'
      machines is because they run at such a slow speed. They need the overtravel to get a head start on ball 2. On an A-2 its at 0 degrees because it can cycle on the 2nd ball very fast. Be fore you change over your machines and take out the overtravel, think about it. You must have a faster motor pulley on it first. Check out the 1 pinsetter thats like that, why did the previous mechanic make that change to begin with.

      I have model 'A' machines with 2 Zot converted, and I left the overtravel in, they go alot faster.

        They are marginally faster but vastly more dangerous, owing to the killer deck holding hook.

          I agree with roscoe about the hook situation, NEVER go under the deck on an overtravel equipped machine when it's on second ball, as the hook is the only thing between you and being 15/16" thick.

          One other reason to get rid of them is that if the wire link gets stretched, the machine will run down to 90, rake down, deck down, and stop. Of course, if you want to keep them, changing the link is the answer.

          Mine run at jetback speed, and the overtravels are mostly all "pinned out" (both clutch levers are pinned to the shaft) This takes the bearing/block/linkage out of the mechanism. Some still have the kit that peanut mentioned, it works well.

          At any speed over original "A" speed, the overtravels are an unnecessary complication, and should be done away with:
