Router table/fence surface
After much planning I have a table, fence, and several jigs designed, the parts list for Lee Valley written out and all that I have yet to determine is what to use for the exposed surfaces of the table top and fence. I will be spending a small fortune on the extrusions, t-slots, bolts, clamping handles, etc. so UHDW plastic is going to blow my budget out of the water.
The table top will be made of two layers of 3/4" baltic birch with some sort of surface for lubricity. I have seen some pics here that seem to have tempered hardboard, and others with an arborite-like top. I like the hardboard over the arborite since it seems less likely to crack and chip, but is it susceptible to expansion from humidity? Any suggestions would be appreciated.
