The noisebridge band saw is a mixed use saw (see safety tip below) for cutting straight cuts in projects that can fit into it's short neck form. This tool doesn't preform scrolling cuts without patience and plenty of backing off to prevent the blades from twisting and breaking.
==What it's used for==
The bandsaw is used for making curved cuts. It is faster and more stable than a jigsaw.


Use a blade with TPI, width,and blade material that are appropriate for your cutting material.

* Adjust the blade guide.
* Keep in mind that the teeth of the blade are splayed out and cut a kerf wider than the blade itself.
* Keep your fingers at a safe distance from the blade and any other moving parts. Don't reach close to the blade to pick up offcuts.
* Wear safety glasses and hearing protection. Both are available.
* Don't use excessive force.
* Never wear loose clothing that might get caught in the blades or other moving parts when using power tools.

# Plan your cut. Set the bed to the right angle, make sure you have enough space all around the saw to complete your cut. Pay attention in particular to the space between the saw and the frame of the band saw.
# Turn on the saw by flicking the switch
# Make your cut. Pay attention to the sound it makes. Stop if you hear rattling or if the saw is bogging down.
# Clean up all the sawdust and offcuts you just produced. Vacuum the motor area.


Note: there are a couple spare 56-1/8" blades lying about, they *DO NOT* fit the working band saw.

==Shop Safety with the Band_Saw==
===Broken Blades===
just a shop safety note regarding cutting metal in stationary tools... the shavings that come off the metal piece being cut (yes, even aluminum) are HOT.  In a stationary tool that has been used on wood, there is typically a nice big thick bed of sawdust inside the tool. When the metal shavings fall into this bed of sawdust, an awesome smoldery fire can build up sight unseen inside of the tool.  yay! Especially if you have a dust collection system you can get some pretty spectacular results this way.
If you broke a blade, replace it by counting the TPI and width and purchasing a replacement according to the specs. Cost: less than $11.00. If you have a car, drive to the Sears in Colma and buy the blade 6-pack; that is the most economical option. Lowes and Discount Builders don't sell the right sized blade.


Be aware of this phenomenon. When possible it is best to have two separate dedicated tools... and/or if one is going to be transfered over into metal service the inside should be vacuumed out first, and/or the operator should check inside the machine when they are done.
===Blade types===
* There are metal blades and wood blades for this saw.  
* The saw is currently equipped with a wood blade.  
* '''Do not try to cut metal with this blade.'''
