I own a what I think is a pre-WW2 unisaw. I have used it for close to 20 years in my small shop. The top ,where it meet the cast iron extension, is either warped or the extension is warped or both. I would say that the don’t match at either end by .004″. I have alway wondered how differently the saw would perform if it was dead flat. My guess is it would preform not differently except maybe when doing miter rips/ Anyone care to comment on this?

Not worth worrying about. PM allows .015" tolerance over the flatness of it's table saw tops. .004 is well within any manufacturers tolerance for woodworking machinery including a jointer. On my old 16" Oliver jointer from the 50's they considered .010" within acceptability. Any piece of wood is going to move more than that if a warm breeze goes by.
Morning again David...
Ditto Rick on this issue which IMO is a "non-issue". You won't see the results of what .004 does in Wood-working. Metal-working is another story!

Not worth worrying about as Rick and Sarge have said. If there is a step where the extensions bolt on you can adjust a little via the bolt holes, or shim to at least have things on the same plane-that is if you want a smooth surface at least.
This is exactly what I thought. The warpage goes up on the extension and down or flat on the tablesaw so there is not much I can do about it. Thanks for the input everybody.
