Shop Safety

Rule number two: Listen to your machines while they are operating. Like operating your automobile, be aware of strange sounds. While a machine is operating, if something doesn't sound right, turn it off!

Rule number three: On tablesaws, feed smaller workpieces into rotating blade with a Push Stick, and/or use Featherboards.  Always feed work into the rotation of the blades and/or cutters. A rotating circular blade on a tablesaw throws wood! Don't rip on a Radial Arm Saw. A router bit, lose in its Collet, rotating at 24,000 RPMs, is a lethal weapon.

Rule Number four: Keep a push stick or push block nearby to complete cuts.

Rule number five: For all shaper and router operations, wear safety glasses, a dust mask, and hearing protection.
 

Rule number six: When feeding workpieces into rotating cutters and/or bits, avoid awkward hand positions; always keep your hands clear of the cutters.

Rule number seven: Before installing cutters or making adjustments, always unplug the tablesaw, the shaper or the router. 

Rule number eight: When routing freehand, clamp stock to a work surface.  

Rule number nine: Do not shape or rout work that is warped or that contains loose knots or foreign objects such as screws or nails.

Rule number ten:  On shaper spindles and router collets, watch constantly for Runout
