Topic tags/keywords: jointer adjustment in-feed table

I am trying to set up an old JJ-6 Jet jointer. I have the manual, but it is not much – 8 pages and not mention of adjusting the in-feed table. My in-feed table is off .006 and I cannot figure out how to make changes to the table. Any ideas? Thanks in advance.

I’m not sure where it is off by .006”. The tables need to be co-planer.
The diagram below does not show any adjusting cams for your setup. Often these machines have the tables ground after they are assembled on the base. That is also why you cannot typically replace one of the tables and expect a good setup. There are 2 bars called gibs, #4 in the diagram, which seem to be some kind of a shim. There are only 2 of them and it seems to indicate one on each table at the back. This diagram is from
On mine, which is an old 4” Delta Homecraft, I shimmed the outfeed table. This one gets moved very seldom if ever and those adjustments are minor. In this way I was able to set the outfeed table to the infeed table and make them co-=planer. It may be a good idea to take the tables off of the base to clean and lube all of the sliding areas. There may be buildup there that is causing the .006” error.
