Preparations for the glue-up for a piece of mahogany and maple. On the recommendation of a coworker, I taped off the areas that were to be glued and put on an initial coat of finish. The finish is oil-based, so the theory is that by having a coat of finish the water-based wood glue wouldn't seep into the wood once the two are joined. This worked out well. After the finished dried and the two pieces were glued, I used a wet rag to remove the glue to was squeezed out. It did not appear to seep into the wood. The joined pieces of wood make a beautiful complement to one an other and this should turn out to be a nice frame when finished.
