I've seen that, but I'll bet you money if you stick two pieces of spruce together with T-88 after they've been sanded, it'll break somewhere other than the joint
+++++++++++++++++++ I have often seen this instruction, but could never see the reasoning. One article by Bingelis took it a step further and said planing is Ok, but not sanding. Surely a planed surface is a whole lot smoother than a sanded surface. In many years of wood work, sanding was one sure way to get wood ready for an adhesive. Removing wax /oil /dirt is the idea - in my view much more important than vacuuming the wood dust - that is no worse that a bit of micro. Maybe the reason is more about sanding a radius into the area to be glued - i.e., destroying the flush fit between the two parts. Steve J
