Tube Fabrication for Tube Setting


#1

Tubesetting fabrication . Figure what the tube diameter needs to be (
measure the stone and add 1 to 1.5 mm ) .

Calculating the width of a Tubing Blank - from Alan Revere’s
Book " Professional Goldsmithing.

" width of tubing blank = ( outside diameter - thickness ) X 3.141 X
1.15 "

or

" width of tubing blank = ( inside diameter + thickness ) X 3.141 X
1.15 "

This is to allow slightly oversized tubing to be drawn through a draw
plate to reduce it to the proper size.

Mr Revere’s Book " Professional Goldsmithing " is a very good
investment.
