Topic tags/keywords: question router

I have a question regarding the adequacy of a router table such as the Jessem or rockler entry level tables that are made of laminated MDF. I live in the south and my shop is not heated or air conditioned, no dehumidifier.

Are these tables stable enough to stay flat in these conditions ? Does the laminate seal them adequately or will they deform over time ?

The laminate seals where’s there’s laminate, but dewaxed shellac will take care of the rest.

FWIW, the key to maintaining a flat router table top is proper bracing underneath. My router table is a sheet of 3/4” MDF with oak braces underneath. It’s flat to within .004”, and has stayed that way.

My table top is two 3/4” pieces laminated together and she’s going on 10 years old. I made it in VA moved it to St. Louis where it was nasty humid all the summer long next to the Mississippi. It’s now In PA. No issues. Hope that answers your questions. I did my own. Glued screwed topped with Formica and wrapped with white oak. She is still as flat as the day I made it.

Thanks for the feedback gentlemen. I will probably go for one then. Not sure yet if I will buy an insert plate and make the table myself llike you did or buy a package from Jessem or Rockler.
