re: CROSS CUT SLED

Ian
I would not use Corian as a base .
I find that applying local pressure like at bolt holes will cause breakage .
I had that problem with a router fence .
I used HDF which is a harder type of MDFwhich I got it in sheat form from a lift of laminate flooring about 3/8" thick .
A little hard on the saw blades so I used cheap blades to cut it .
