I am currently in the process of fixing up my old Delta contractors saw.
Well first I noticed the saw was a heavy 1/32nd out of flat across the width (side ways , crossing the miter slots). I took the tube style fence rails off to see if they where bending my top out of flatness. They WERE. But my top still isn’t dead flat.
Across the width its high in the middle, by the blade. It causes one side to be off by the thickness of a playing card. But when you only check the flatness of HALF the width of the table (where your good piece you just ripped will sit) its almost dead flat. If you check the width behind and in-front of the blade opening its much flatter. So its high around where the throat plate goes by a LITTlE LESS than the thickness of one playing card. Is that acceptable? I want to start doing precision work (joinery, ripping, crosscuts).
Any advice or opinions would be great!
(And yes the extension tables are removed, everything is, trunnions, arbor etc. I checking just the table casting on a workbench.)
