Router Table For Incra LS Positioner (25")
I just purchased one of these (Hartville Tool is having 20% off until the end of June on all Incra) and must build a new router table top to accommodate it. My current table uses the MDF sandwich (3/4" + 3/4") with formica laminate on each side. I want to try a different route to reduce costs a bit as well as work with a material I've always wanted to work with but never had a good excuse - baltic birch ply.
The commercial table size sold for the Incra 25" model is 32" X 53". I plan to modify mine to dimensions of 28" x 53". If repeat the MDF sandwich of my current set-up, it will require 2 sheets of MDF + the cost of laminate and contact cement - about $120. As an alternative, I'm contemplating building the top from two 3/4" layers of baltic birch ply laminated in a vacuum press. I could get by with one 5' x 5' sheet for about $60. Also, I wouldn't laminate with formica. Instead, I would apply multiple coats of polyurethane for protection from moisture/abrasion. I realize that I may need to re-coat periodically.
Does anyone have experience with this type of top? Does my planned approach raise any red flags? Thanks.
