All those tables with large epoxy pours down the middle look great but how do they go over the years with wood movement? Is the bond that good? As some of these have anything up to 200mm of epoxy between the (often slab ) timber. Have used clear casting resin (polyester I think) tinted up and with some dried sap mixed through quite succesfuly for larger gum pockets however the scale of use that I've seen on some of these would worry me.
