I'm working on a (two-piece) hutch for SWMBO, and I've been considering the options for joining the bottom/frame to the top unit. (Note: I'm not talking about attaching the flat surface to the base unit; that's something I always do with glue-blocks.)
I DAGS and found the usual options. Use a connector on the back (figure-eight or the "stacking connector" like LV carries), use a dowel-pin and let gravity do its job, or use a cleat or fastener to attach from the inside. I had also considered cutting mortise into the top of the base unit and tenoning the frame members of the top to fit, but that seems like a lot of work for very little advantage to be gained.
So, do any of youse have actual experience with the various methods? Would you care to point out some gotchas to be aware of or simply suggest your favorite options?
At this point I'm leaning a bit towards the connector method, and maybe cutting some molding to dress up (i.e., *cover* up) where the two units meet. But I'm struggling a bit with it because I tend to be a traditionalist (read: Neanderthal) and use metal fasteners only as a last resort.
Any suggestions are appreciated.
