I have decided to add a router table to my table saw to save some space. My question is, would 3/4" MDF base and 3/8" UHMW top be sturdy enough to hold the weight of the router?
Would 3/4" Plywood be better for the base?
Does using UHMV for the top make sense? Will it adhere to the base with contact cement? I have only used it for zero Clearance inserts, very laminated it as a top.
I've used this medium for miter slides, router plates and table saw inserts. (all resting in slots and screwed in) Around here, they have been selling these large, very inexpensive cutting boards made from UHMV... I never thought about making a whole tool table from it...
I would think that it would hold the weight... with the real challenge is rather of adhering anything to UHMV. Back around 2005, no-one thought that a hobbiest could glue anything to it. (a slick surface that nothing sticks to...) That has changed since. It usually takes a 2 part adhesive/epoxy that will stick to roughed up polyethlene.
