   Rich: I have glued up a 44 inch wide 5/4 poplar panel once. It had eight 5.5 inch boards with the grain cupped up and then cupped down on each successive board. The ends were not attached to anything, and thus were allowed to float. It may split if it were not allowed to expand and contract.

   *My thoughts exactly!The smaller width will give less curl if you oppose grain directions.24"x9'is most that I've done.Poplar is less stable than some other woods but is inewxpensive and is nice to work with.

   *If it's gonna be painted anyway, I'd rip, flip and reglue 8 and 9" boards in thirds. For that matter, I'd probably use 6/4 MDF or 3/4 MDF with a built up edge.

   *Stan, piffin, thanks for posting so quickly. I was having a lazy attack. Took the boards up to a friends straight line saw and cut them all down to between 3.5 and 4.5 inches Will glue up tomorrow with opposite grains. Thanks again, Rich

   *Suggest you use the small biscuits, the big ones occassionally telegraph in poplar.

   What's the widest width poplar glue ups anyone has done? I am getting ready to glue up some 6/4 poplar FaS for a counter top in a library. Approx. dimensions are 14' X 30". Most of it will be supported by cabinets, 4' of it will be supported by a ledger at the wall and a corbel on the end. The boards I have now are 8" to 9" wide. Material now reads 6% moisture content and shows no signs of cupping or warpage. It will be primed and painted on 4 sides and covered with a clear glass top. Has anyone ever glued up boards this wide with long term success? My gut tells me to rip them in half and then do the glue ups....just wondering.
