Wheel Guard (band saw)

the upper and lower wheel guard protect you from the wheels of the band saw. both wheels are removable to change blades

wheel tires

both upper and lower wheels have a rubber tire. rubber protects teeth of blade and provides traction for drive wheel and blade

Ripping on band saw

to get best results rest hand on table and use thumb as mini fence

Lead (band saw)

if the teeth are sharper on one side compared to the other then blade will wander towards the sharp side. carpenter must compensate for lead.

Ripping dowels (band saw)

rounded stock tends to rotate during a cut. causing the sides to be spiralled. to prevent this use a vertical splitting bar behind the blade. clamping a block with a v channel and nail poking through will allow the cut to not spiral.

Ripping small sections of dowels (band saw)

clamping two blocks to either side of dowel so it sites flat on table will allow you to rip dowel without spiral

Bevel cuts on band saw

table is tilted to desired angle

make a test cut and check with a protractor

Cross cutting and mitring with band saw

should not be done BUT if they have to then carpenter can free hand OR with the help of a mitre gauge.

Circle cutting on band saw

always start cut across the grain.

circle should be laid out so that the line is approximately 6mm (1/4”) from the edge of stock because a poor blade will runout

circle cutting jig procedure (band saw)

drive a nail into the plywood to act as the circles pivot point. this must be perpendicular to front of the saw. the distance from nail to blade is radios of circle.
Drill a small hole in centre of the circle. make sure its one radius length from one edge and slightly more from the other three edges
place the board with its centre hole over the nail. place the shortest side towards the blade. to cut the circle rotate the work clockwise until the full circle is cut.
if you find the blade is leading to the left adjust the jig so the pivot point is slightly ahead of the blade
if it is leading to the right, move the pivot point slightly behind the cutting edge of blade.

Cutting curves (band saw)

requires blade to have little or no set Make relief cuts

if a blade for band saw has little to no set will it cut in only a straight line? T or F

true

when do you make relief cuts (band saw)

before you start cutting

what do you do if you need to make a sharp internal corner while cutting on a band saw?

pre drill holes at corner

Three different types of blades for band saw

Fabric cutting blades Metal cutting blades Wood cutting blades

Fabric cutting blades (band saw)

has a wavy curvey blade used for slicing through material not leaving a saw kerf

Metal Cutting blades (band saw)

- will be labeled as metal cutting blade and will have 14 to 24 teeth per 25 mm

Coarsely- toothed metal blades for band saw are used to cut...

brass copper and aluminum, metals that do not spark

Teeth on metal cutting blades have three different types (band saw)

1. wavy set 2. Regular set 3. Every tooth set

Regular Wood cutting blades (band saw)

had 4 to 10 teeth per 25mm | this results in a cut with two smooth sides and allows for interact cutting

Skip tooth wood cutting blade (band saw)

has 1 to 6 teeth per 25mm | this is used for ripping or re cutting thick stock

Control switch (drill press)

turns power on and off

Quill (drill press)

Inside the head of the drill press there is a vertical sleeve called the quill. contains a rotating shaft where the chuck and drill bit are attached.

quill clamp(drill press)

used to lock quill in position

Depth stop (drill press)

used to stop drill when holes need to be exact depth.

Feed lever (drill press)

feed lever rotates the pinion shaft

Pinion Shaft (drill press)

moves the quill up and down while drilling a hole

Spindle (drill press)

is a rotating shaft that is inside the quill

Chuck (drill press)

mounted at the bottom of the spindle, this holds the drill bit. can hold bits up to 12mm

Table (drill press)

supports the work. can be raised or lowered can tilt to allow for angled holes

Table clamp (drill press)

holds the table to the column. when the clamp is loose, the table can raise and lower and swing left to right.

Column(drill press)

vertical shaft that supports the table and head

Base (drill press)

Bass supports the column it should be fastened tho the floor.

Belt guard (drill press)

transfers power from the motor to the spindle. the belt is usually mounted on a pair of step pulleys. this is located at the top of the drill press and protects the entire belt system

Drilling holes in metal

Lay out location smaller holes may require punch for larger holes you may need to drill pilot holes use lube while drilling into metals.

Drilling holes in wood (drill press)

sharp bit and correct speed. too slow and it will tear the wood, too fast and it will burn the wood. when boring completely through a piece of wood place scrap piece behind it so that it does not tear the piece

Hole saw bit

Ready available in sizes ranging from 3/4-4"

Spade bit

also called a speed bore, relies of tearing rather then cutting action

Plug cutter

used to make plugs and shot dowels.

Multispur bit

is equipped with brad point and a number of teeth on its perimeter.

Auger bit

used for boring deep holes in wood.

Forstner bit

used for making holes with flat bottom.

Mortising bit

used to make rectangular holes
