HOW TO USE A JEWELERS SAW
Begin by inserting saw blade into frame and drawing it tight.
To do this, loosen both wing nuts parallel to the handle. Insert blade into nut next to handle (teeth are angled down towards the handle) and tighten.
Adjust length of saw frame as necessary to accommodate blade and tighten.
Insert blade into second wing nut. Make sure blade is taut before tightening this nut. To do this, press end of frame against a hard surface so saw frame bends inward slightly, tighten nut. When you release the saw you will have a tighter blade. You will be able to test the blade by strumming the dull side with your thumb. If it is tight and has a slight ping sound to it you will know that you have a good tight fit.
How to Use Saw
Lubricate blade with beeswax to protect it and reduce friction when sawing.
A bench pin or piece of wood with a “V” cut out of it and attached to your table is what most jewelers use. It allows for the metal to sit on top and the blade to work inside the V. It also helps to ensure safety.
Holding the metal with one hand, begin with a small cut on the edge of the sheet. Continue cutting along your pattern turning the metal rather than your saw as the direction changes. Allow the teeth of your blade to do the work by keeping only a minimal amount of pressure on your saw. Blade. When you get to a corner, back off the blade a bit, keep sawing and you slowly turn the metal and then continue to follow your pattern.
HINTS: (From Experience) It is common to break blades. It is usually caused by twisting when sawing or applying too much pressure. Keep your work to your left (if left handed) or to your right (if right handed) and saw straight up and down. If you try to use the saw in front of you and between your knees, you will break more blades as you will naturally twist the blade.
