Its been nearly 15 years since I replaced two ancient garage door openers and because of their heavy construction could not bring my self to consign them to the dumpster. Unlike newer home units these used a sturdy steel "T" beam to support the drive chain and sliding door attachment. Ever since their acquisition this pair of derelicts has languished in the overhead of my shop gathering dust, but now they are about to provide a solution to an old problem, namely gluing up flat panels. No matter how I have tried, glued panels have always wound up with a slight bow unless I have used a couple of planks and clamps to hold them flat until the glue sets. I intend to use the T beams as gluing clamps after I have cut them to usable length and removed about 2 inched of the T on each end to receive a C clamp. I figured 38 inches should be adequate for 99% of all the panels I will be working with and now a 2" C clamp will easily handle holding 3/4 inch stock flat between a pair of beams until set. No more using wax paper to keep unwanted items from gluing themselves together.
