Dedicated fixtures are for production or at the very
least commercial work where there are funds to cover the cost of those
fixtures. Those of us doing personal projects don't like to waste
perfectly good material on a one off fixture.

Fixtures can be as simple as a waste plate with a few bolts through the
workpiece. *If it changes for every new workpiece layout, it is *- in a
sense - a "dedicated fixture".

heh...one of my first memories when I got my job at _American
Machinist_ and started visiting job shops was the "fixtures" rack in
one particular shop. I thought it was a staging area for cutoffs and
scrap.

There must have been fifty of the things on that rack. I wonder how
those guys remembered which one was for which job. *g

Usually fixtures are stamped with a customer name and number that
corresponds with the drawing.
