Jim and Larry, and others,
Thanks for the responses. The fact that the machined joints will mean nothing since these are wooden boxes for my manufacturing plant. The boxes will all be painted! What piqued my interest about the 4212 is that you can also do through dovetails and box joints. Now typically, I would hand-cut the through dovetails, but for "knocking" a dozen boxes every month or so is using some of the precious little shop time I have!
For even considering the 4212, I'll be thrown off all the handtool forums I participate in, however, like most participants, I believe most, if not all do use a number of powered machines.
To change direction for a bit: Jim, are you the guy who had the picture displayed recently in Woodworking mag? Nice job if so!
Finally, how hard is it to adapt one of those hand cranks that tension bandsaw blades on the back of the machine, to a router, to turn the router bit to negate the use of the power cord? Failing that, any ideas on how to hook up pedal power?
