Where do Jet clamps rank? This set is $260 on Amazon, $200 on my

The blocks are shown in the CL listing, no mention of the bench dogs.

Jets are ok,Â* You want to oil the screw PIVOT point where it meets the
big washer end, not only the screw itself.
Also these type clamps normally do not need passing to prevent denting
the wood.Â* NOT THE CASE with Jet.Â* Jet clamps imprent the work.
Not that I'm planning on buying them, but what is different about the Jet
clamps that they damage the wood?
I am not sure, but there are straight line imprints on the wood at the
edge of the clamp faces.Â* It is probably the hard plastic that they use,
it apparently stays flat.Â* I would guess that the Cabinetmaster and
Bessey clamps have a little give on the surface and they probably leave
a less visible smoother arc shaped indention with out leaving a defined
imprint.
If you look at the back side of the tail end jaw, you will see two flat
sections of steel bar stock used, horizontally on the left and right
sides of the jaw. These are covered in that plastic housing, which is
the only thing on the flat/clamping section of the jaw that presses
against the wood.
The handscrew end has a steel box-like structure, covered in the plastic
housing, but there is steel across the section that presses against the
wood.
The tail end jaw has the edges of the steel bar stock pushing against
the plastic, and against the wood being clamped. Obviously, the hollow
middle section has more give than the edge section which are backed by
the steel. So the imprints you see are the edge sections where the
steel is on the edges.
Very poor design, imo.
