  • Ball returns

    I have balls that sit on the back edge of the shaker board. I shimmed the front end up to tilt back more and still does it. Might be to much of a gap from frame to ball elevator. Any suggestions on what I should do? I haven't tried a different shaker board yet tho.

    You might have a hump at the rear edge of the clamping plate. You can cut out the middle section of the shaker frame to let the ball roll off easier. I believe if you leave 2-1/2 at the ends and remove the mid section, it will make an improvement. Also a zip carpet would help too.
    My father told me to never get old...I should have listened!

      So it's alright to cut the mid section of a frame? I thought the shaker board is suppose to slide in that groove?

            Before you start cutting anything, make sure your upper BW guide rollers are correctly positioned to seat the ball wheel. If you don't have at least a 3/16 drop off you're domed to have ball calls no mater what else you do. Add washers to the back of the lower pit frame if the BW is already seated and you don't have the drop you need. You also have some movement in the elevator feet holes and pit frame mounting holes that might be abele to reduce the gap if you loosen the carriage bolts and shift them together.

              Just like Kanga said. But I prefer to use caster and camber shims. Can be found at auto parts store or a auto repair shop. Makes the job a snap.

                Yes, it's safe to cut the rear clamp. Basically once the pit board is slid into position, the front clamps push the board to the rear and it's held firmly in place.

                The worse that can happen is for the pit board to slide from side to side; and it'll happen no matter how tight you get the clamps. A simple method to keep the pit board from sliding is to make a bracket from an ordinary hardware store part. I made a few from bent ball track supports. Steve Stafford has the dimensions for the hardware store item.



                They don't look pretty; but, once the pit board is sitting on top, nobody will notice.

                  Hmm ok I'll have to try and experiment. If all else fails just put another frame in.

                    Leave 3" of clamp on each side.

                        Are you saying that the ball sits in the gap between the shaker frame and the ball wheel?

                          The problem may be as simple as replacing the 50 yr old rubber strips on the bottom of your pit board.

                            Where EXACTLY is the ball sitting?? Is it off the edge of the shaker board against the ball wheel?? Sometimes older carpets wear in the rear of the board right in front of the clamp. The carpet gets a dip in it where the ball sits in and doesnt enter the ball wheel. I'm with checking the rubber on the bottom of the pit board and making sure the ball wheel is seated on the lower guide rollers.
