  • Need Help Badly

    Right-o, here's the scene.

    82-70s. XLi upgrade, although I think it's moot, just wanted to throw that in.

    Table adjustments go nicely. Get the table level and happy. Next I go get my 1/2 bubble to rear. Cool. So far so good. Next I go for my little daylight gap of 1/16" between stop bolt and stop. Here's where it gets screwy. I CAN GET NO GAP!! Doesnt matter how much I turn the spotting rod, the stop bolt never raises up from the stop. Help me please.

    A few things: the machine height is awesome at 19".

    The spotting rod is the correct length (32.5 inches)

    Everything spotting-related is sound. A slight bit of wear in spring hangar and a little slop in table actuating link assembly (worn bushings) but nothing major.

    I cannot get the damn 1/16" gap to save my life.


    Twice today I was told that in older machines (which these are not) you needn't necessarily have the gap AT ALL. If this is true, then what the blue sh*t do I do with the spotting rod for that step? Where do I leave it.

    I'll be looking in, I hope someone can help. Thanks in advance.

    Not to sound obvious but, is the stop bolt out too far? is the spherical bearing in the lower part of the leg in good shape? if no adjustment is obtainable, grind down stop bolt till there is.
    Don't mind me, what you read is invisible.

      Table too far to the front?
      Missed that one on your checklist...
      So it goes.

        It sounds to me like you need to crank the table the opposite direction that you cranked it to get it in the position that it is in right now.

        I believe I had the same problem before and that is all it was.

        Another thing the half bubble is only a starting point you may half to go one way or the other. Its been awhile since I have had to make those adjustments so I can't tell you for sure what way. I think it is just when the whole bubble falls towards the rear of the machine. Is where I normally adjust them at.

                  Also did you slide back the Collar before you did the 1/2 bubble ? I'm sure you did, But just checking.

                    Stahl's method: Crank table down with spot latch engaged with pins in cups until bottom of pins are 5/16" from pin deck. Back off stop bolt until good air gap or more. Combination square reads LEVEL by turning spot rod. Screw stop bolt back down until bolt touches stop and tighten. Cross level then go back and re-check level so the bubble in still in the center or plumb. If it is off, make sure there is no stress on stabilizer rods and table is level, than re-adjust from square one. Maybe I explained assbackwards. Does anyone have have comments on this method?
                    Yeah but, We've always done it that way.

                      Brunsamf, thats exactly the method I learned at Stahls. The biggest thing with using that method is to make sure it reads a level bubble on both sides of the head pin shaft.

                        Holy crap, im more confused than ever.

                        Kenny, go on with the wrong direction of cranking motor. Tell me why one direction matters over another. Seriously, im all ears. Thanks guys, even those of you that are insane. Keep it coming.

                          Also, Wang and Bruns, turning the spotting rod with a bubble/level on that shaft (yes, with collar removed ) doesnt change level of bubble. It rotates the pins, yes, but doesnt change the pitch. Does that make sense?

                              <font size="2" face="Verdana, Helvetica, sans-serif">Pinmonkey what old school is trying to tell you is that if you crank the table down the wrong way and get to the position that you want for the adjustment you are actually on the upward stroke of the table instead of the down stroke. Try this; run the table about 3/4 down with the motor and then continue to crank with the crank. Unlike the STONE'S, think this will give you satisfaction.
