First started using a jeweler's saw during my tool and diemaker apprenticeship but using one was a rare event. Never did like a jeweler's saw because overall it's a slow way to remove excess sheet metal. ....especially if one doesn't use it often.
Since getting into MLer gunmaking, I only use a jeweler's saw for piercings in sheet metal.....all the other sheet metal removal on all the parts is done w/ a hacksaw and then a coarse file....much faster than a jeweler's saw ...no multiple blade replacements and it's surprising how fast excess sheet metal is removed by sawing close w/ a hacksaw and then using a coarse file.
Also, multiple parts can be made at one time , the BC cheek stars as an example.....3 pcs of 1/16" thick sheet silver are held together w/ super glue , the stars are cutout w/ a hacksaw and then a coarse file and finally finished w/ a fine file. The center screw hokes are also drilled while attached. When done, the 3 stars are heated w/ a propane torch and fall apart. The same is done w/ the Pbox sideplates although the difference in length of the ends that touch the Bplate have to be allowed for. Of course edge draft has to be filed on before inletting, but this has to be done irrespective of the saw used.
As a toolmaker, speed was important and one's raises were based on how fast a die or mold was built and that's my excuse for a habit that seeks the fastest ways to make a MLer, but w/ high quality still maintained.....Fred
