That job in Charlotte where the client wanted a built-in with no visible fasteners at all
It was a solid two weeks of my life I won't get back. They wanted a full wall unit for their living room, floor to ceiling, but insisted on no screws, no nails, no plugs, no nothing showing. I explained that even with a sliding dovetail or a stopped dado, you need some mechanical fastening for a piece that size. They wouldn't budge. I ended up using a massive amount of specialized cabinet glue and a crazy number of bar clamps, some I had to rent. The stress of waiting for each section to cure, hoping the alignment held, was unreal. It turned out fine in the end, but the profit margin was gone after the extra glue and clamp rental. Sometimes, is the 'perfect' look really worth the extra headache and cost?
