Re: Table extensions on AD 741. A warning

Did you try opening and closing the outfeed table to see if the drop still persists? If you moved the outfeed vertically to be even with the cutter head, did you do it in the up only direction? You don't ever want to come down to a point with the jointer tables, always take the slack going up. Just a couple of thoughts....

For the first time I decided to use the cast Iron table extension that is usually attached to my shaper spindle moulder to my planer jointer out feed. ?I was planing some 10¡¯ x 10¡± x 1 1/4 and thought I might benefit from extending the surface to help achieve a flatter, truer board. ?I set the extension up to be perfectly level with the out feed table.?
so far so good and the added surface helped support at the end of the cut. I think I probably always use the end of the outfeed table to pivot longer boards or use it as a point to rotate the board onto its side ready to carry it back for another pass. ?I didn¡¯t deliberately do this on the extension- more so that I didn¡¯t lever it out of level relative to the out feed surface. ?
Next day surface planing up some smaller boards I noticed something was amiss. ?First thing was the stock hitting the out feed just after the cutter on fence side. ?I could pass a board over cutter at the front of the machine but it was taking more from one side than other. ?I presume the out feed has moved and I would imagine this is due to the extra leverage of the extension.?
The table sits comfortably on the cathedral bolts at the front and they aren¡¯t loose ( as in neither have loosened or undone). ?
The out feed tips away from the cutter head by 0.80 mm with the in feed and out feed tables married up at the cutter head.

Fistly, am I missing something obvious? ?I am really hoping not to have to ?recalibrate the tables. ?I don¡¯t have any of the specialist dials / gauges etc. A while ago I tried to set up a Hammer planer / Thicknesser that a colleague had attempted to adjust. After many hours I failed and had to call in Felder Techs - ???????$$$$$. ?
Any input welcomed.?
