Default 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!

On my home made table with a particle board top I couldn't see light under a straight edge. If you can it isn't flat enough in my opinion.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Geez that would be disappointing. You would think manufactured ones should be dam near perfect
I'm surprised they didn't send you another instead of having you bandaid the issue

You should send one of your unused drones there way

I'd arrange for a replacement. Rockler has been good for that. I don't think there is anything that is perfectly flat, but I would think that any significant warp would likely reappear despite shimming. Call Rockler direct and speak to a human to arrange a return, the HQ, not the store. I have the same table and it is fine.

A return of the problem is what I was afraid of, I think I will get back with Rockler and see if they can help me out. In the past I have had nothing but Outstanding service from them so I don't think this will be an issue.

If a well jointed stick, heading to the cutter, rocks up & down:
The thing is unsafe, can provoke a self feed. spoil a profile, is unfit for joinery
and plum needs replacing.

Default Rockler's reply

Spoke to the folks at Rockler, the young lady said she didn't know much about Router Tables but knew they were supposed to be flat without being shimmed so they will be sending out a new top and it would have a return label inside for this one.

I asked if it wasn't too much trouble to have someone put a straight edge on it before they shipped it out to which she replied she would make a note but didn't know if they were pre-boxed or if it was possible.

Anyway I decided to use a level and straight edge to check all the mounting holes in the metal stand and get them as close to flat as I possibly can before the new top arrives.

Does anyone have any suggestions that may help ensure I get and keep a flat table top?

Your wife is most understanding and generous. Does she have a sister?
