Marco: I have a bench that was originally made for the Ithaca Gun
Company for gun engraving. It has a maple top with a round steel
plate mounted on a steel rod at the center. The rod passes through a
gimbaled bearing to a kick wheel at floor level. A machinists vise
is mounted to the round steel block (the block is about 1 1/2"
thick). You can rotate the vise with your feet, much like a potter’s
kick wheel. You can adjust the position of the lower kick wheel
forward or backward, thereby changing the angle of rotation of the
vise. The bench measures 36"X18"X 36"h. Probably weighs about 150
lbs. With the vise removed, you can attach a tray or plate to the
round steel plate on the bench top (I used carpet tape). Works great
for large engraving.
Unfortunately, I don’t do much large engraving, so this beautiful
bench just sits in my house collecting odd tools…
