I haven't been on the forum for a couple of years. Retired and that has taken most of my time. My last posts were mostly about building workbenches and that with other workholding solutions has been my interest for the last year or two. I've had simple criteria, the workholding system had to be easy to build, inexpensive, portable (fit in the motorhome bins), easy to take apart and put together with just the use of a mallet, the modules have to be transportable by a single person, and last and most important hold the workpiece without compromise. I've come up three units, the first is the Moravian workbench thanks to Will Myers there wasn't much butt scratching involved. Will just copied an original Moravian bench and I copied Will. The Moravian bench can be scaled from small to large shop sized, I've built both and both work a treat. The next was a shave horse. I built a couple of different styles settling on a 'deadhead' horse because it allowed the head module to be fixed to the the horse base with a wedge meeting the put together/take apart with a mallet requirement. The third is a spoon mule. The horse and mule share a base but have different holding requirements. The horse "clamps" from the top where the mule "clamps" from the sides. The mule clamping module is pretty simple much simpler to build than the horse module but, there is always that but, it took some fiddling to get everything working.
Bottom line I've three functional workholding systems that meet all the above criteria.
