Hello,
In looking at a Jointer (J/P actually in this case), how flat is flat enough in the infeed/outfeed tables? Would you use a feeler gauge and quality (Woodpecker) straight edge... or a dial indicator for even more precision? And what would you be looking for across the width, and length of the tables for a high end machine, e.g.; Felder AD941.
Thanks,
Izzy

I use feeler gauges and quality (Lee Valley) straight edges, and try to get under 5 thou for aligning tables to be coplaner. So tables themselves need to be less than that.

A dial indicator is not going to help to measure anything. I use a precision straight edge from suburban tools. I would look closely at the infeed and outfeed area closest to the cutter head.
I also have the Lee Valley straight edges.

Straight edge and feeler gauge, gaps should be .1mm or less.......Rod

Use a straight edge and feeler guages. But make sure the edge has certificates guaranteeing straightness to some accuracy.

Best advice I can give: buy, beg, borrow or steal a copy of "Care and Repair of Shop Machines" by John White. He has practical, common sense, and economic procedures, clearly written, on aligning/setting up a jointer, as well as table saw, drill press, planer, band saw, and other common power tools. Get it NOW! (I have no financial or other interest in the book, just a rabid fan of it).

I second this suggestion! It is absolutely one of the best books in my woodworkers library; my go-to book for setting up & maintenance of shop equipment.Originally Posted by John Donhowe

Should the straight edge be the full length of the table? 48" in my case. Or can I use a 36" one?
Thanks for the book recommendation! I have one on the way. Thanks to Gail I have saved $5 to be applied to a straight edge purchase

Yes, yes, yes, this is a great book! -Howard

Spoiler alert! White shows how to make a very accurate straightedge from a length of mdf- read the book before springing for an expensive straightedge.Should the straight edge be the full length of the table? 48" in my case. Or can I use a 36" one

Thank You, ordered it as an Xmas present for myself. (from Amazon)

Ultimately you will want a straightedge the length of the combined tables. I have a Pinske edge and when I checked it against my 8' extruded levels, I found them to be close enough to check jointers. Dave
I just ordered the book, too.
I bought a 50" straight edge on Amazon 0.003" across the 50" for a little under $50.
