Router Table Top Advice
In the planning phase for a knockdown router table (gotta be knockdown because of space limitations). The table top layout/construction will be similar to the New Yankee Workshop Deluxe Router Station. The table top will be supported at two locations, similar to the one in the attached photo (the bottom structure will be different). [whoops, site says the pdf is too big to upload - I'll try an alternative :( ]
Since the table top will have to be carried to and stored against a wall, weight is a consideration. Stiffness and flatness is also a factor.
So, I'm looking at two alternatives. Either two pieces of 3/4" MDF, laminated together, as per Norm, or some sort of a torsion box arrangement.
I've built some torsion box shelves that turned out with an incredible (at least to me) strength/weight ratio, so I'm intrigued with the possibility of having a stiffer, lighter table top than I'd have with the two pieces of 3/4" MDF. Maybe 1 1/2" thick with 1/2" MDF on top and 1/4" on the bottom?
