   Hi Paul –

   I have the Delta DJ-20 (8- inch) in my shop, which has the extended in-feed table. At first I was also puzzled by this feature. It is my understanding that to improve accuracy you would increase the length of the out-feed table. With use however, I have noticed that very long boards are much easier to stabilize and control with the added length to the in-feed table - I suspect this is the rationale behind it.

   Thanks Darrell. That makes sense. Have you noticed ####sigificant difference in jointing long boards with the
   DJ20 infeed table as compared to a shorter infeed table.
   The reason I ask is that I'm favoring the new Grizzly 8"
   jointer G0490 which has 3Hp, the longer infeed table
   and parallelogram bed levelling over the Grizzly G0586.
   It (G0490) also has a built in mobile base. So for $50
   more by the time you buy a base for the G0586 it seems to
   me you are getting more machine.cheers,Paul

   Paul – Yes it seems to be significantly easier to handle long boards when compared to a jointer with a shorter in-feed.

    I have a friend who recently bought the 8-inch Grizzly with the parallelogram bed – he is quite happy with it.

   Darrel, Did you ever notice that the blade set bolts are hard to remove. My bolts were soo soft that I had to grind them out. There are 4 to a knife

   Hi Lou,

   Do you have the Delta DJ-20?  I have never had a problem  removing the knives - but I did have to grind down a wrench so it was thin enough gain access.

   Yes I have the dj-20, I to had to grind down one of my good wrenches too. Hate when that happens.

   A longer infeed table on a jointer does have an advantage beyond just making the stock easier to handle. 

   A up bowed board that is longer than the infeed table will be forced to rise a bit as the trailing, overhanging end is dragged up onto the table as the board is fed into the cutter.  Because the board is being lifted, the straightness of the cut is thrown off and it will take more passes, and usually waste more material, to get a straight edge on the board.  You can still get a straight edge on a board that is longer than the infeed table, it will just take a bit longer.

   Bowed stock is usually fed bow upward on a jointer because this is the most stable way to feed the stock.  If you feed the board bow down, to avoid the problem of the overhang riding up on the table, the piece may rock, like a rocking chair rocker, frustrating any attempts to get a straight edge.
