Tools Used to Separate Material
Basic Rules of Cutting & Shaping o The larger the cutting tools teeth, the more material will be removed. o The farther the cutting tools teeth are from each other, the rougher the material will be. o Hence, the larger the teeth and the farther they are from each other…. the greater amount of material removed and the rougher the surface.
Basic Rules of Cutting & Shaping Cont. o The wider the blade the straighter the cut. o When using hand tools (power or manual) use both hands. o Use jigs to guide a tool through a material. o Use fixtures to guide material through a tool. o Always clamp down projects when passing a cutting tool through a material (power or manual).

Saw Teeth Direction Cutting Stroke The position of the teeth determines what the direction of the cutting stroke will be.

Elements of Machine Tools
Cutting Motions o
General Band Saw Safety o Set Guard height ¼ - ½ above thickness of material to be cut. o Only use the guard adjustment knob, never the blade tension (top) or positioning knob (back). Guard Adjustment Knob
Band Saw with Fixtures Use RIP FENCE to make repeated Or long straight cuts Use a MITER to make angled or straight cuts
Scroll Saw Chattering o Due to the reciprocating Up nature of the blade, the material can CHATTER (move up and down rapidly). Down o Avoid chattering by holding down firmly on material while advancing the material
Scroll Saw Additional Information o Adjust table height by loosening the adjustment knob under the table. o Jigs and Fixtures are not needed due to the freestyle cutting techniques. Adjustment Knob
Drilling General Rules for Drilling Make sure the bit is straight and secure in the chuck before starting. Make sure that the key is removed from work area before starting. Always clamp projects down to the table, or in a table vise. Always return drill bits to case when finished Proceed slowly when advancing the drill bit

Aligning the Drill Bit & Table o The hole in the center of the table is for the drill bit to pass through. o Align the bit so it can pass through the hole. o The idea is for the drill bit to go all the way through the material and into the hole…not into the table.
Aligning the Drill Bit & Table If the drill bit is to large to fit into the hole……. Get a piece of scrap wood to cover And protect the table.
Belt Sander o A minimum of ½ inch material thickness is required to use the sander. o This thickness provides adequate material to grip the material while using the machine Belt Type Sander
Disk Sander o When using smaller pieces of material, (on a counter clockwise rotating disk sander) use the left side of the table. o This will keep the material securely on the table
Portable Belt & Palm Sanders o Always secure material in a vise or with a clamp when using belt sanders and/or palm sanders. o Never use any sander unless all the safety guards are in place.
Sand Paper o Used to smooth objects, 100 Grit 320 Grit 150 Grit remove small amounts of material, and do minor shaping. o The number on the back determines how many sand granules per sq/in. Also known as grit. o The larger the number, the more grains per sq/in.
