A few questions.

>"Biggest problem I've had with wood stability is in the support beam for edge planing."
Mike, could you expand on this. What was the problem?
Also, is the support beam stiff enough for mortising assuming that it is supporting the workpiece from below whilst clamped with the front vise?
"Two dog holes, one on either side of bench, near the end vices allows you to clamp odd shaped pieces, like chair seats or circles. I'm not sure you really need the two end vices in that case. One should do."
You mean that one pipe clamp down the center would be enough? Would one clamp work even with the original design assuming that one had the rabbets for the mdf fillers?
"Objection to lag bolts into end grain is valid. Of course, you can rebuild the whole base in a couple of hours and at very little cost. However, threaded rods the whole length or carriage bolts with nuts set into drilled holes will take only a little longer than the lag bolts."
Or mortise and tenons.
Mike, did you implement the pipe clamps for the front vise with the holes spaced on 6" centers? If so, how do you like it?
It does appear to be a very low-cost, innovative design that most beginners could build with limited tools and which has all of the functionality required for hand tool work and more.
