  • Table set-up

    On setting up a table today (82-70) I closely followed the manuals instructions. Set up a 5/16ths clearance from table to pin deck, at its lowest position. Put table down to 6 inches of deck and got out my set square. Managed to get half a bubble to the rear of the machine on the spirit level as stated, by adjusting screw (stop). Finally set up respot rod with 1/16ths clearance at stop (when base of pins are 5/16ths away from deck).
    All went well untill i did a re-spot cycle on the machine. When the table came down to feel for pins, the cups touched the tops of the pins.
    Why did this happen when I achieved all the correct adjustments stated in the manual?
    Should I have adjusted the yokes so that the half bubble on the gauge should be facing the front of the machine and not to the rear? [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img]

    Re: Table set-up

    Double check that your Table BDC is 5/16 throughout the entire table.

    In other words, make sure the table is level. (side to side and front to back) If not, adjust accordingly.

    About the book, the steps do not emphasizew enough that after you set your 5/16 BDC you must crank the table backwards (reverse rotation) to get the table 6" off the deck to set your yoke.

    Half bubble toward the rear of the machine.

    You sound like your doing fine, just double check your work.

      Definitely sounds like just a bit of fine-tuning is needed yet...

      Remember, though... if your machines are older and have some time on them, the book will usually only get you close. From there, you may need to tweak the settings a bit to compensate for wear & tear.

        My machines that I work on or 30 years plus, with little or NO planned mantinance done to them!!

        I have set up two tables today as stated in the manual, but both of them the same problem occurs. The cups touch the pins on re-spot cycle!

        Unsurem about BDC terminology?

        Have had to shim table posts to ensure a level table. ie, left to right.
        Have achieved roughly 5/16ths all round table when at lowest position!
        Dont have any gauges, ie 5/16ths plates, that the manual sugests, to put under machine when adjusting forward and back measure, but used rule to square table, using the 1, 7 and 10 pin spots.

        Things I have done today was to set up the table with half a bubble to the front of the machine! This brought the cups more forward on the re-spot cycle. ie. the pins didnt touch the cups as much as they did when a half bubble to the rear of the machine was achived.

        But still there was a little interference. ( pins put on there spots).

        Should I raise my table ( clevis) or shoud adjust the re-spot rod, for beter clearance. ie a later pull back of the cups?

          I would suggest leaving your adjustments by the book like you stated, but raising the clevis 1/2 turn and see if that helps. I too have had problems with pins hitting cups, and usually a have turn higher helps.

            King's method.

            1. Do all adjustments by the book.

            2. After pins are on spot and do not fall over during spotting action....go back to bubble adjustment and adjust bubble until bubble is in the middle.....this allows more room and does not effect spotting.

              Unless I'm mistaken, the half bubble adjustment is the adjustment for the yoke moving away from the pins.

              As long as your pins are setting correctly and the yoke moves away smoothly (without knocking over pins) then go ahead and raise your cups to see how she runs.

                After you adjust the spotting rod for the 1/16" gap get rid of it by adjusting the bolt. Or just stop the table when the cups are hitting the pins and udjust the bolt.

                The half bubble adjustment is to place the bolt in the propper place so you can adjust the spotting rod. After that, you can pretty much get rid of the gap.

                  alastair, the half bubble deal is simply the angle/pitch at which the front yoke is in front of the table X-frame bearing welds, which ensures toe-in (the pin hitting on its toe as opposed to its heel which would cause the pin to rock forward [img]/content/btubb/images/%%GRAEMLIN_URL%%/usflag.jpg[/img] and become saddam, i mean deadwood [img]/content/btubb/images/%%GRAEMLIN_URL%%/usflag.jpg[/img] )

                  coors' quick set...make sure head pin cup is equidistant heel to toe..... shorten spotting rod in until spotting latch no longer falls over spotting lever..... lower table in respot!!, set set screw til pins are off pin heads...if not already.

                  lower table to spot til pin bottoms are an RCH from hitting deck, extend spotting rod til head pin is over spot (this action will lower table as you lengthen rod, and so crank table higher as the spotting rod action lowers it), lengthen set screw til screw is a BCH perhaps 2, from table frame.

                  adjust table height (3/4" wrench and box end ratchet) under power accordingly. <<--now for fox, you dont adjust while running, you watch it run, unplug, adjust, and then plug in.

                            I HAVE ALSO HAD THIS PROBLEM! THE HALF BUBBLE ADJUSTMENT IS TO PROVIDE THE CORRECT AMOUNT OF TOE-IN REQUIRED (FOR THE BEST SPOTTING ACTION).
                            IT SOUNDS TO ME LIKE YOU NEED TO RAISE YOUR TABLE (AS LONG YOUR TABLE AND PIN DECK HAS NO MORE THAN 3/8" CLEARANCE IT SHOULD STILL SPOT FINE). IF THAT FAILS THEN GO FOR A 1/4 BUBBLE (BUBBLE TOWARDS REAR) OR A LEVEL BUBBLE WOULD STILL BE OK. GOOD LUCK MATE [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]

                              Dear Hammer,

                              Have adjusted the table as suggested. BUT you neglected to mention that you MUST HAVE a half bubble to the REAR of the machine to start with in order to set up the re-spot rod correctly!!

                              If you do not have this clearance then ALL your adjustments will be incorrect!

                              Note :- after you have adjusted the re-spot rod, only then can you go back and and get the centre bubble or quarter bubble to the front, as you suggested.

                              Thanks to all you guys who helped out in this matter. Coors method of doing it is very cowboy-ish. So tell me coors how do you put the spot rod out of adjustment, so that it doesn't latch, and then expect to put the table down to spotting in your next adjustment!?!
                              Too many beers for you my lad me thinks.

                              Anyhow THEHAMMER, you've got a pbl to pull tommorow and a naughty lane hanging pins (bent finger rod galower).

                              82-70 KING am on your wave length with this one, and KAT. Your help is great as a re-assurance that im doing the right thing.

                              Cheers Alastair. [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]
