I made some rough calculations yesterday afternoon (bored at work!
) - and based on the results, I wonder if 0.011" upwdard deflection of the top is possible for a cast steel tablesaw top. I was calculating 2000 lbs force required minimum... Then again, I may have made some bad assumptions on the table thickness and I didn't account for the opening in the table very well either.
If the table top settles down over time - that soulds like creep to me. I'm not sure if cast steel will creep much - usually that requires a sustained load.
Well - let us know how things go - I'm interested to see what happens!
