Intro: HOW TO USE a JEWELRY SAW
This is how to use a jewelry saw. Off course you can just go ahead and use it randomly, but with just these few tips, everything will be way easier.
Step 1: WHAT YOU NEED
-a jewelry saw blade,
-a piece of wood (cut as in the photo),
-a good clamp.
Step 2: CHOOSE THE BLADE
There is many chart online for how to choose your blade depending on what you are cutting. But in general as hard as your material is, as thiner the teeth of the blade should be. For metal at list two to three teeth for as thick the sheet you need to cut is. Thiner blades can be more precise, but they also break way more easily.
Step 3: BLADE DIRECTION
With your finger feel the blade direction. You have to place it in your saw, so that it will cut by pulling, not pushing.
Step 4: PLACE THE BLADE
Place one end of the blade in the part more near the handle. Screw it tight.
Step 5: THE OTHER EDGE OF THE BLADE
The other edge of the blade should not quite arrive to the other side of the saw. It should miss few millimeters.
Step 6: PUSH AND PLACE BLADE
Push the saw against something, holding it from the handle, so that the blade will reach the other edge.
Close it really tight.
Step 7: FEEL THE BLADE
The blade now should be really tight, and make a nice sharp sound.
Step 8: WAX THE BLADE
Wax the behind side of the blade (not the front part with the teeth).
If you never did it before, you should give it a try: it really make a difference when cutting metal.
It make the blade get less stocked, and make it move easier and smoother.
Step 9: CLAMP THE WOOD
Clamp the wood very firmly on a table. I did my piece with a scrap piece of wood and a jig saw.
Step 10: CUT
Place yourself in front of the piece to cut. Don't push too much the saw, or the blade will easily break.
Keep the saw in the middle of the wood hole, moving the piece you have to cut with your other hand.
WEAR GLOVES ON THE HAND THAT HOLD THE PIECE TO CUT, THE BLADES ARE REALLY SHARP, AND EASILY CUT TROUGH YOUR FINGERS.
Step 11: IF YOU NEED TO CUT AN INSIDE PART
If you need to cut something in the inside part of a piece of metal, just punch a little hole where you need to cut, insert the blade in the hole, and do the previous step of how to place the blade and cut.
