As a Cabinetmaking student I feel I should be part of this discussion. Although, I've only been at it for a couple months, and worry that when school ends in April I'll still be pretty useless to woodworking employers. My teacher expects you to remember all the tricks and plans in your head pretty much, there's no step by step instruction sheets like one paying to learn a new skill would expect.
Rob's work really is gorgeous. Though, even if his dovetails and mortise & tenons fit perfectly, not using any glue/screws/plugs to strengthen the joints seems strange. They're what holds the piece together when the air moisture content changes and makes the wood expand/contract.
For the most part I've just built random stuff so far, a guitar stand, bandsaw boxes, a sawhorse, wooden puzzles, etc. I remember in the Jobs thread some other poster gave me a little advice about working in the field, but if any of you have experience in cabinet/furniture work I'd love to get more insight.
