  • Head Pin Through the Shuttle

    Does anyone have an answer for the headpin sliding through the shutle down into the table? The pin seems to stand up somewhat verticle on the way down and get itself through. The shuttle adjustment at the back is correct. All parts are good. Pics are always helpful.

    Re: Head Pin Through the Shuttle

    We had that problem from the head pin in the second rack not laying flat and square to the lower one on the pin holders... When the machine would shuttle, the upper pin would kick toward the rear of the machine, then would kind of 'hop up' and fall through.

    Make sure the distributor is centered on the #1 bin rail guides first of all... if it's swung too far right or left, it'll cause pins to lay crooked in the second set. Sometimes all you need to make this stop is a distributor linear spring stretched between the pin guides to the front and back of the #1 bin. All it does is slightly slow the pin down when it falls into place on the shuttle, and keeps it better aligned to the pin guides.

    I've seen guys install 'funnels' on the #1 bin to help guide the pin and keep it laying straight... that also works, but requires riveting parts on to the bin.

      Make sure your distributor height adjustment is not too high over the bin, if it is it can cause the 1 pins to have too much speed coming into the bin slot causing it to hit the butt plate and stand up or shoot through the bin.

      Some mechanics will lower the 1 pin tracks down in the back by 1" to reduce pin speed, but this can cause pin damage in many cases.
      Please.....follow the instructions!!

        <font size="2" face="Verdana, Helvetica, sans-serif">Because of the pin damage potential, we raised all of our #1 chute rails in the front. This way the pin slides into the bin pocket flat. At the end of the rails, the pin falls "flat" into the pocket just like any other position.

          The two pin guide shute rails must be parallel to each other. If the guide rail roller wheels are more open at the lower end, the pin will stand up and drop through (while being delivered) as the table is spotting. Run the table down and feed some wood out to the head pin.

            Other things to try

            Put washers on the last two rollers. (makes the pin drop a little farther out) Also helps index the trip lever.

            Make sure there is a strap across the shuttle rails. (keeps rails from bowing)

            Play with the shuttle adjustment. (set the shuttle back alittle more) the book is just a starting point.

              I took off all of the rollers except the bottom two and those two I changed to stationary ones the same size as the rollers. They are made of glass filled nylon so they don't wear out. You can stack the pins three high and they settle in nice and gently because the nylon knobs offer resistance. Be sure to file any burrs off esp. the top of the 5 pin butt spacer. I have yet to have a problem.
              Yeah but, We've always done it that way.

                Take off all the rollers.

                Use ball track plastic for rails instead.

                You only need to cover the 1st 3 holes toward the distributor.

                The pin cannot fall through prematurely.

                  Distributor height is the primary cause also check your alignment as stated above [img]/content/btubb/images/%%GRAEMLIN_URL%%/cool.gif[/img] i hate those plastic rail things everwhere i go i rip them off [img]/content/btubb/images/%%GRAEMLIN_URL%%/mad.gif[/img]

                    How high is the distributor from the bin? Is this adjustment changed at te base of the dist?

                      <font size="2" face="Verdana, Helvetica, sans-serif">I raised the front of ours by adding a couple washers under the 2 spacers/bolts at the front of the distributor support where it meets the crossbeam... doesn't take much... 1 or 2 washers will raise the front of the dist. about 1/2"

                        Ensure that the rubber bumpers on the pin butt guide are in tact and not damaged.
                        If the distributor belt is too short this will stop the ditributor from feeding the head pin into its bin location correctly. It can cause the pin to stall. When shuttling the pin will stand up in the bin and eventually cause it to either go through into the table or not to shuttle at all, leading to out of sequence and pile up.

                          another thing we used to do when I was doing installations for AMF back in the 80's was carefully spread the indexing fingers on the end of the distributor apart just a little. this will also slow the pin feeding into the #1 and also helps feeding at all other pin locations.

                            <font size="2" face="Verdana, Helvetica, sans-serif">I took that one step further and shifted the rails back towards the distributor. It cut the gap between the rails and the trip arms, creating a smoother transfer between them.

                              Also.... I didn't see anyone mention it above...

                              Make sure the pin holders in the shuttle are not worn.
