How flat should flat be?
Made a bare bones router table and it has been fair to use but wife went with me about three weeks ago and saw some commercial tables at a Woodworking store. Sweet as she can be she wanted me to get a new router table for a combined Birthday and early Father's Day gift. I have been blessed, she is a real gem.
Last week during Routermania at Rockler I bought the HPL Top Stand and Fence Combination and saved a bunch of money on my car insurance. Oops I meant on shipping as well. Anyway I put it together last night and in general fit and finish is very nice.
However, after I put it together I found major discrepancies to it being "Flat." Every corner was high when compared to the center of the table. I checked the plastic edge banding, that was not the problem. Talked to the Rockler folks and they suggested I shim it where it is low and retighten all the screws.
Being its a brand new top I thought I shouldn't have to do that, but decided to give it a whirl. I made the measurements with a feeler gauge about 1 inch from the opening for the plate.
As you look at the table starting at the front of the opening for the plate and going clockwise it originally was off by .045 front, .040 left, .037 rear, and .045 right. After shimming it I am now down to .006, .010, .008, .006. Obviously much closer than to begin with, then I thought maybe I was being overly critical of this.
Since I know you all for the most part have much more experience than me I am back to my question is How Flat should Flat be? What would be an acceptable tolerance may be the more intelligent question.
Thanks in advance for your input, hope you are all well and having a great day!
