Bought Rockler Combo package with cast iron table, dust collection, lift, fence, etc. Got the table up (weighs 44 kg), installed the dust collection box, and the next step was to level the router plate and lift in the opening with the 8 hex screws (turned from the bottom, which is insane I admit). Well 3 hours later and with a super sore arm from lifting that heavy plate and lift out each time to try and adjust so my square does not catch across the table top I finally got it so it does not catch from the left or right in either direction. But, then I notice the plate is below the surface of the table at the top and bottom - yes, it is actually looked concave. My square also caught from on top and bottom of the plate moving it up and down. I took the plate and lift out and put it upside down of the flattest surface I know-my Sawstop and was able to get a feeler gage - .007 under the center of the plate (both sides) but not at the right or left sides. So, that confirmed my visual - it is concave in the center.
Now the question(s) - does it:
a. Matter? (Concerned the bits will be lower than they should be with the wood going across the bit.)
b. Is a return worth contemplating? (If one plate is concave I bet all of them are - my experience with metals is that a 3/8”+ thick aluminum plate is concave because of the casting or rolling process.)
c. Is there a possible fix?
I would have considered something else (Kreg, Jess-em, etc.), but the table top, stand, and what I thought was its general OKness made me go to Rockler. Big pain also is the adjustment screws turn from underneath the opening in the table and are locked into place with a nut and a lock washer which, when tightened, makes perfect adjustment an issue. However, it is pretty and the rings snap in and out and that is nice.915C417F-0D16-4689-BECC-495246799DF6.jpg
