Well perhaps this is a semantics thingee :-)  But the question is still 
relevant, i.e. if the thingee is going to be put in a "vise" what are the 
"clamps" for? :-)

 It is possible that S&S wanted to keep the terminology very simple and, 
without going into mind numbing detail, allow some glimpse into the making of 
their rims. In the book, Steinway and Sons, there is a series of pictures 
that show quite clearly the rim building process..sans "vise"..sans "press" 
but with lots of "clamps", "cauls" and men.

 Hey if I turn out to be wr.... er, mista......not correct, it will still be 
a beatiful day here. :-)


David also said:
<<"I think the clamps are used to get the rim close to piano shape before 
fitting the press?">>

 Well OK but is it "a press" or "a vise" ? :-)
If it is truly either than couldn't the "clamps" be done away with?

 Just for consistency I offer the following definitions:
Jig- a fixture to allow subsequent operations to be performed as to desired 
parameters of shape or form thereby allowing the replication of forms/shapes.

Vise-1. A clamping device of metal or wood, usually consisting of two jaws 
closed or opened by a screw or lever, used in carpentry or metalworking to 
hold a piece in position.

Press-1. Any of various machines or devices that apply pressure and create 
new forms or structural alignment.

Clamp-1. Any of various devices used to join, grip, support, or compress 
mechanical or structural parts.
