  • running a PBL without...

    thimbles on the bottom will do what?

    I shimmed out the lift rails on a pair and then the thimbles started putting dull scratches on balls (thought they were there to avoid this??). Took them off and no more scratches or problems as of yet. But it seems there's a lot of exposed metal down there. Am I going to cut up balls or what?

    You Shouldn't but I did it for about 2 months with no probs. long term I would say there'll be lots of huge golf balls around...........

        They are called ball guides. All they are suppossed to do is to help center a ball as it is being lifted. I have them istalled on most of my machines.

          I wouldn't advise running a PBL without the ball guides. A ball hitting the end of the rail where the exposed screw is leaves a very nice crater. It would be rare when it happened, obviously, but it would only need to happen once to really damage a ball.

            You will get ball damage and split lower rail covers. maybe not at first but you will hae problems.
            Please.....follow the instructions!!

              Try the orange AMF urethane thimbles, they work great!
              I don't think our machines would return any ball without a thimble{metal or urethane) but I've never tried it and I ain't gonna try it...
              So it goes.

                I've never seen the orange ball guides. Are they as durable as the metal ones?

                  Humpbacks are installed without thimbles.

                  I would think you could survive a PBL without thimbles easier dur to the ball already being centered.

                  You could use the lower Lifelong rail covers for durability.

                    Thanks for the tips. Shimming the lift rails really helped with the yo-yo's but I cant leave it like that at the expense of cut balls. Urethane ball guides sound safe enough. Got a part # for those?

                      Its also possible I went over board on the shimming. I used 1/4" thick steel washers because I wanted to see if shimming the rails actually worked or if I was just wasting time.

                        <font size="2" face="Verdana, Helvetica, sans-serif">Yes they are. However they do have the plastic/urethane one-piece ball guide that mounts on the top of the lift arm bracket and protrudes into the area where the thimbles would be on a PBL. I purchased 4 used humpback systems and one of them had a broken one piece ball guide, so I used the metal PBL ball guides instead. They worked just as well.

                          I would think that the thimble / ball guide is a necessary.

                          I tried the shimming out of the rails and it worked ok, but then I moved onto installing the thimbles and AMF's gripper up-rails. The yellow colured ones made from neopropane. No need for the whole expensive PBL upgrade kit. Just install the rails and adjust the PBL accordingly.
                          They work very well so far!

                              Does anyone have a picture of these ball guides? From what has been discribed I don't have any on my PBL's. Never even heard of them.
                              There is always more to life, but would someone tell me what it is!
