  • Falling Pins...Please Help

    We have 30 year old pin spotters and i think due to all the deck resurfacing we have done we are having problems with pins tipping over during spotting. Im wondering if anyone is having this same problem and what are the best ways to fix falling pins during spotting.
    Also, we have had some problems with pins falling through the bin during spotting. Is there any other major adjustment other than the shuttle rod ? Thanks ~jake

    Adjust the table to be square with the deck.....the deck is probably low in the back from sanding.....adjust the table tilt rods....then go through the spotting adjustments.

      Given the years on re-surfacing, you may need to adjust your A & B frame sections to accomplish what you're looking for. Of course, you will need to adjust tables after doing this like Jerry says. With numerous cuts, you have to keep lowering your table to get the 5/16" above pindeck at spotting, but then you increase the gap between the table and shuttle when the table is at 355.

      Yeah, there's Mickey Mouse ways of achieving the same result by flipping shuttle brackets and over extending swivel rods, but I think it's more trouble free to drop the frames and re-zero everything from there.

        You got alot of adjustment with the clevis and the levelling rods.

          Many years ago I worked with field tech who said a-f never made anything within 1/4''. I have seen machines in bad shape.You know your good when you can make a 3-legged dog run like Gazelle.

            you can lower the frontend assy and turn the clevis back in to elimnate the double shuttling problem double shuttling is caused by to much gap between the table and shuttles.by lowering the frontend assy and raising the table this is bringing the table closer to the shuttles..and then you will be able to achieve the spotting of a good solid rack providing you make the adjustments..

              How does one go about lowering entire front end assy./main framework?

                <font size="2" face="Verdana, Helvetica, sans-serif">After breaking loose the bolt holding front and back frames together, loosen jam nuts on jackscrews holding front-end frame to kickback unistruts. Turn jackscrews in required direction (in this case CCW) to obtain 35 3/16" between the bottom of the upper cross member on the side frame and the pindeck. Tighten jam nuts for jackscrews. Gap between front and backend should be about 3/8".
                After doing this you WILL need to re-adjust S &amp; T and possibly shuttle to table relationship.

                        You may want to check your Cushion Shock Absorbers, you may be experiencing balls rolling on the Front roller for a brief period, this can cause the pins to fall if the Table hits the ball.

                          you can level front ends to the lane as follows.
                          if they are 82/70 with alluminum tables then make a jig to fit under the stud on the kickback but long enough for the base to rest on the lane and cut the top corner out to fit under the table when at zero. make the length exactly 19 1/8" high which is the height you require from the pindeck to the bottom of the machine frame at the four stud points.adjust each stud point to achieve this 19 1/8" and lock off the studs.This is the correct height for an 82/70 aluminum table.
