i'm about to begin making a router table extension for my table saw and looking for some advice.
will two sandwiched pieces of 3/4 mdf make for a more solid top or just more weight that could lead to sagging? does it all just depend on the bracing underneath?
i've seen mentioned that it's necessary to put formica on the underside of the mdf if you put it on the top. is this true? i've seen 4-5 shop-built router tables in professional shops with formica tops that don't have it underneath.
lastly, i have been planing on installing the router towards the outside of the table and mounting the 17" incra fence towards the inside. will it be tedious removing the fence every time i need to use the tablesaw and should i consider mounting the fence towards the outside and the router towards the center. this would make for a slightly longer table and would take away the convenience of standing on the end. any thoughts on this?
appreciate any help,
andy
