What is Nova Labs?
A non-profit Makerspace
What is a Makerspace? (per Wikipedia)
A Makerspace is a physical location supporting a collaborative environment and community.
A maker's facility usually provides access to community tools and people with a wealth of knowledge.
Given access to these resources, community members are able to learn and complete projects, which would otherwise be out of their capability.
How is the space funded?
Through classes like this, membership dues and donations
How do I become a member?

Slide6Introduction
Slide7So, what is it?
…a
woodworking tool consisting of a circular saw blade, mounted on an arbor, that is driven by an electric motor (either directly, by belt, or by gears). The blade protrudes through the surface of a table, which provides support for the material, usually wood, being cut

Slide10What is it used for?Guiding workpieces through a cutRip – Cuts along the length of a workpieceCrosscut – Cuts across the width of a work piece
Angled – Angling either the
Bevel – Angling the blade at an angle other than 90 degrees or perpendicular to the table
Miter – Setting the crosscut angle to an angle other than 90 degrees
Non-through cuts – Cutting a
Rabbets – Non-through cut along the outside edge of the material
Dado – Non-through cut across the width of the material
Groove – Non-through cut along the length of the material
Cove – Non-through cut that is made at an compound angle across the length and width of the material
Slide11AlternativesCircular Saw – Handheld counterpart!Band Saw – Capable of performing similar cutting operations, but with a significantly reduced change of kickbackMiter Saw (Chop Saw) – Designed for crosscuts

Slide13Safety
The best safety device is an educated mind who can recognize when something is not safe and stops to rethink the approach.

Body Position/Posture and Movement
Be aware of where your body parts are
moving at all times
Be prepared to stop the saw at any moment
Do not reach over the blade
Slide15Safety
Operational Safety
Dust Collection
ALWAYS
Unplug before making setup changes
Minimize blade exposure
Set the blade height to clear the material (1-2 teeth above the material)
Refer to the
Table
Saw Safety Guide
for more
information
Table Saw Safety Checklist on page 5
Use the right blade for your operation as described on page 7
Slide16Safety
Safety Accessories
Fingers != Push sticks –
Keep your fingers at least 3” away from the blade at all times
Featherboards are your friends
Jigs and Fixtures to assist with operations
Refer to pages 11 – 15 for more information
Slide17SafetySawStop Brake SystemPatented system which monitors a small electrical current on the blade
Fires a solid aluminum brake block into the blade if the electrical current drops
The aluminum brake can only be used once.
Can be triggered by anything conductive, such as…
Aluminum
Nails/screws embedded in reclaimed wood (use a metal detector)
Excessively wet wood
Refer to the SawStop Table Saw Recertification Guide
for
more information.
Slide18SafetySawStop Brake SystemThe aluminum brake can only be used once and destroys the blade in useThere is a minimum of a $200 fee to cover the brake and blade for ANY brake triggers
The SawStop Table Saw is
only for cutting wood
!
Avoid accidental
triggers
Refer to the SawStop Table Saw Recertification Guide Table 1 for more information.
Slide19SafetyFeeding your Material through a cutMaterial MUST be flat with a reliable straight edge to reference against your guide
Wood moves and does not stay flat
The planer and jointer should be used to flatten any material that is not flat with a reliable straight edge
Always feed the material straight through the cut
Use bevel angle as appropriate
Use miter gauge/sled/crosscut table, jigs, and accessories as appropriate
Never ever attempt a freehand cut!
Slide20SafetyFeeding your Material through a cut (cont.)Never use the rip fence and a miter gauge/sled/crosscut table at the same
time
Focus on the 3 key points of pressure
Downward onto the table
Inward to your guide source (rip fence or miter gauge/sled/crosscut table)
Forward through the cut
Make sure your material clears through the blade
Slide21SafetyMaterial SupportSupport your material throughout the cutDon’t put yourself in a position where you are fighting to balance the material
Use proper infeed and outfeed support
Never reach over the blade to try to grab/catch your material
Secure your material on the keeper side
Keep the good face of your work down to prevent splintering
Back up your cut with tape and/or sacrificial backer pieces
Slide22SafetyKickbackKickback occurs when the teeth of blade is unable to slice through the material, and the momentum of the blade pushes it back towards youThis can happen for many reasons, such as dull blades, pinched blades, or an improper feed rate
Kickback can happen during rip or crosscut operations
Always use the guard for through cuts
Always use the riving knife non-through cuts
Make sure the blade fits the guard/riving knife kerf and plate specifications
