Re: CNC router - making hive boxes?
I've done some NUCs from Advantec on my Camaster Stinger II 4x4 with no problem. Obviously, the joinery was incredibly precise due to the nature of the cutting method and that made the rabbit joints tighter. We don't generally build "boxes" because honestly, it's less expensive to buy knock-down from Mann Lake than it is to buy material in most cases, but I'd do these NUCs and so forth on my CNC again in a heartbeat.
Don't worry about finding pre-made designs...you can't get more simple than drawing things out for them in whatever design software you use (Vectric V-Carve Pro for me) and the tool paths are simple. Just remember to cut the rabbits first before you do your cutouts and depending on the material you are using, make your tabs thick enough to not crumble if you're using something like Advantec.
