Tuck of Spaghetti, California sent in these pictures and description of his Moxon benchtop joinery vise. Tuck's Moxon came out quite nice. His bench ain't too shabby either.
Here's Tuck's description.
This is a Joinery bench. It is designed as such utilizing the
hardware from Benchcrafted for the double-screw vise based on Joseph
Moxon. Why a bench on a bench? The behemoth upon which it sits is
perfectly-situated for planing and a host of other activities. However,
to cut and chop out material at a comfortable height it’s simply too
low. It quickly gets uncomfortable hunching over to measure, mark, and
make a saw cut. Worse, it doesn’t allow me to comfortably grasp the saw
with the delicacy of holding the hand of a toddler; a much-needed
technique for myself for smooth sawing. Ditto for chiseling.
I’ve seen some great solutions to this problem. One of the simplest
(and best, having tried it) is Jim Tolpin’s clamping support shown here and here.
However, there are a lot of other operations that are made easier with
a raised platform. Sketching, carving, anything that needs closer
examination. Too many to mention.
This version was designed with some consideration. The pinch-points
for the support of the bench were specifically sized so that they would
be squeezed into place between two dogs. Further, a small pad was
added to sit just in front of the dogs, pushing the plane of the fixed
jaw surface flush with the front of the bench surface upon which it sits
– thereby supporting the work at the front of the stationary bench.
Adding work between the jaws is aided here because that work is also
pushed into the front of the larger bench’s 4-inch top. When putting
the bench in place, a slight tap with the palm lines it up perfectly
flush. No holdfasts needed.
Both jaws were lined with suede for gripping and to protect against
marring the work – though one alone would’ve been fine there. The
movable chop was made thicker – to deal with any possibility of racking –
and laminated so that the strength of the grain direction would aid in
this endeavor. Its component stock is turned perpendicular. Finally,
the benchtop and fixed chop were also laminated for added strength and
rigidity. The entire thing was made from leftover parts from the
