Ball sticks on backstop

[Mike Anderson]

Every once and a while the ball will stick on the backstop behind the ball door. I'm new at this but the bounce board is not broken. Do I need to raise it.

Any help much appreciated!

first, check cushion, see if ball is sticking to cushion facing, or rivet. reactive balls have a habit of stickin like glue to rivet heads. baby powder will stop that for a while

second, place a washer under neath the rear dampner to angle bounce plates forward.

Rivets will do it, also check your shock parts. Excessive wear in them will cause play and balls idling against the cushion.

I usally cut a block of wood about 1" x 4" and install it on the ball door side of the cushion between the hanger and the plank. This seems to help with balls idling at the door. I also recommend the "Super Blue" rivits that AMF makes. They don't seem to get as sticky from oil.

Check the collar that holds the cushion shock spring up... if thats loose and a ball is thrown hard enough, it might make that slip down enough that over time you'll have this problem because the shock/spring lengh shortens... so the cushion stays back too far, so check the shock/spring length with what it should be. OR... it could be a bad shock, I've seen shocks so bad that if a 16 LB ball is whipped it'll compress the shock.. and it will take a few *minutes* for the spring to push the shock back to full length....

Oh, and lastly.... if you're still using the old cushions with the foam rubber layer... make sure that the foam layer hasnt slipped/torn off/been destroyed.... it could stay back there if that cushion can slide around (and if you use rubber rivots you might not notice the thickness change)... Just some ideas....

I’m with Coors on this one. Sticky rubber rivets &amp; worn facings are the most common cause of balls idling against the cushion. If the facing is worn enough the rubber cushion pad will catch the ball &amp; not allow it to roll.

Angle, pn 000-022-878, being bent downward won't help either. Creates little hollow just behind bounce plate for ball to sit in. Newer style has two supports on bottom to brace it, otherwise they bend rather easy.
We have several lanes that took new angle and wood block behind cushion plank to get balls to the door.

Reactive resin balls: you gotta love 'em for some reasons, but hate them for this. I have brand new machines. . .no worn facings, bent parts, sticky rivets, and I still get this hair-puller.

One fix I heard from a veteran mechanic: Save all your old curtains and facings. Cut them into pieces the size of facings, and about a foot long. Cut holes to match the new facing's upper two and middle end holes (ignore the bottom). On a machine where you're having the problem, remove the first two upper rivets and the middle one just below those and install this new piece with three new rivets. It will cover the lower rivet.

Is it a shocker that Ed would sell a perverted curtain?

<font size="2" face="Verdana, Helvetica, sans-serif">GREAT IDEA!!! I have never thought of doing that before. I have many times wanted to see if someone was throwing a ball on a 70 and couldn't see a thing.
