Well, the decision is in - I plan, Lord willing, to build the "Ultimate Shaker Workbench" by Fine Woodworking magazine. I will be making it a few inches deeper and will probably adjust the drawer arrangement, but basically the same plan.
I obtained some 8/4 thick cherry and 4/4 soft maple yesterday for the timber frame base and the side and back panels.
Today, I put the miter saw and table saw to work, rough-cutting the blanks for all the structural parts of the bench base. After all that cutting, there was a marked scent of cherry wood sawdust in the air!
