I have been shaping on home made 2x4 racks for a few years now (mainly short boards). I have begun to shape longer boards (8' range) My problem is simply this: The longer the board, the more it rocks when I reach either end of the blank (due to the fact my racks were built with only short boards in mind), because they do not adjust for the various lenghts. My question is this: Is there a company (website) which builds the steel adjustable racks (shaping & glassing)? I would like racks that adjust for heigth and length. Thanks for any info you can provide.
