  • Cushion the triggering mount

    There has been lots of talk about mounting triggering heads on the kickback nose. Brunswick nose blocks (armorframe kickbacks) are not an issue as they are not connected to the insert, but mounting on any kickbacks where the nose is part of the original kickback extension has caused what is described as vibration - alignment - false triggering issues.

    Here, you can provide cushioning to eliminate the cycling and/or alignment issues.

    The hole for the mounting screw is drilled out so the threads don't grab the mounting plywood, or bracket, just the kickback nose.



    Then, 2 layers of self adhesive foam tape is placed under the mount. (I lovingly call it politicians tape - IE 2 faced)


    Of course, peal off the backing. This foam tape sticks REAL well.


    Then, I use the mounting screw to press the tape to both surfaces.


    Now, it's important to loosen the mounting screw a bit so it isn't actually pressing the mounting bracket/plywood down. The screw now becomes a back-up to the tape in case something hits the mount and trys to loosen it.


    Bowl Tronics, and possibly others, had a gromet in their bracket, but with this AMF triggering head under the downsweep, some of the triggers had issues with vibration. I suspect the kickbacks may not be as tight as they were 50 years ago when installed. This foam tape was 100% effective in eliminating the issues on those few of 72 lanes.

    Not all of these 72 lanes were having issues, but I did change the mount to this cushioning on all the lanes and there have not been any issues since.

      Ted, were things loose before? I have Mendes which are pretty forgiving and I just rebuilt all of my toilet seat covers and I did,nt have any ball detect issues. (not yet , fingers crossed)

          What is sometimes called the 'toilet seat' is also sometimes refered to as the 'horse collar'. It's the capping piece that surrounds the downsweep on AMF installations.

          There were about 10 lanes that they said the trigger units kept going out of alignment. These houses are 50 years old, and I suspect some of the kickbacks weren't as tight as they should be, or perhaps not blocked in front.

          The mounting screws were tight until I decided to provide a cushion. Now the 'politicians tape' mounts the plywood, and the screws are intentionally lose, but provide a mounting back-up if something or someone knocks the plywood lose.

            They did not include that piece at my place or the old mechanic took it out
