is this an interior or exterior sign? CNCROB is right about the preglued panels they will resist warping well because they have been dried completely. If you are using this outside then nothing beats cedar(redwood) for the price and its rot resistance, white oak works well to but it's pricey. I'm not sure if these can be bought glued up though. If you do glue your own, cut your strips fairly narrow (say 2 inches) and pay close attention to the end grain orientation. When looking at the end of the boards arrange them so that the "cup" is alternating up/down/up/down and so forth. The boards will warp a small amount (you can't prevent this) but at least this way it will minimize it. Because the strips are narrow and you glued them up properly you the board will remain "flat" |
