Re: AD941: Getting outfeed table coplanar to cutterhead
¿ªÔÆÌåÓýLooking at your level readings, I would have no problem working out the twist in your table in less than 30 minutes by altering the relative heights of the two temple bolts. You should not have to resort to making adjustments to the hinge side of the outfeed table. ? If your table has dips and hollows even with the latch and hinge side adjusted coplanar, there is nothing you can do to correct the irregular surface of the table, but you can certainly bring the latch side into close conformance with the hinge side. ?With a table that has excessive dips and hollows, and if you are using a precision level to check surface alignment and conformance, ?it¡¯s best to do all your level readings atop a known-good straight edge with parallel surfaces along the entire surface to average out the low spots. ?I dispute your claim that you ignore my advice, but instead do your best to average out the irregular surfaces of the table using a long straight edge or precision machined contractors level as your point of reference. ?And it will never be perfect, but you should be able to attain flat results with material run on either the hinge or latch side of the machine. ? I do agree that this set of adjustments is tiresome and frustrating, and it takes a lot of trial and error to get it dialed in. ?And it¡¯s made even more aggravating when the machine from the factory is aligned to produce a spring joint result rather than flat surfaces. ?This sets the stage of the user to have go through the tedious process of realigning the tabes after delivery - unless all they do involving a jointer is make cutting boards. ?The source of this frustration is fully documented in my ¡°analysis¡± write-up and the reason I routinely recommend potential buyers look for a parallelogram-type table elevation system when selecting a machine that has flip-up tables. ? If the Andrew¡¯s outfeed table is latched down hard against the two temple bolts, there are only two potential circumstances where the latch and hinge side of the table elevate at different rates: ?A - the eccentric cam that elevates the table is physically different on one side from the other, or B - the pivot pin in the hinge mechanism is moving because the locking set screws at each end are not secured to the shaft thus allowing the hinge to flex when the table is moved up or down.
