what are the 4 basic accessories that are commonly used with a table saw?
- 1.blade gaurd
- 2.splitter/antikickback fingers
- 3.rip fence
- 4.mitre gauge
what should be used while cutting on the table saw when the distance between the saw blade and the fence is less than 100mm 4"?
which basic accessory fits into the slots machined into the table saw table running parallel to the saw blade?
radial arm saws are particularly good for what type of cutting?
fast accurate cross cutting
what are the 3 basic design types of a radial arm saws?
- 1.single arm
- 2.double arm
- 3.sliding overarm
how do you set up a slightly warped material so that it is safe to cut on the radial arm saw?
so that it touches the table at exactly where the blade cuts
what are the names of the 2 set ups for ripping using a radial arm saw?
when ripping with the radial saw, it is very important that the stock be fed against the blades rotation and that what 2 things are in place and properly adjusted?
- 1.blade guard
- 2.anti kickback fingers
what measurement on a band saw determines the maximum width of material that can be cut?
the throat measurement which is the difference between the blade and the machines vertical support
keeping the blade running in the centre of the bad saw's wheels is accomplished by adjusting what?
blade tracking the blade is centred when it rides in the centre of the upper and lower wheels
what are 2 reasons for choosing a band saw to resaw material?
- 1. the capacity to cut thicker material without the risk of kickback
- 2. by using fence and a wider blade you can accurately cut thinner strips
the size of a jointer is determined by the length of the _____.
which part of a jointer is raised up and down to regulate the depth of cut?
infeed (front) table
besides producing flat surfaces and square edges, give 3 examples of other operations that can be performed on the jointer.
- 1. rabbet
- 2. tapers
- 3. bevels
what shape will the resulting cut be if the outfeed table on the jointer is set higher than the knives?
if the thickness planers are only good for one operation, what is it?
to machine the wood to a smooth and uniform or parallel thickness
what must your material have before you can plane it, and which machine should you use to prepare your material for the planer?
one surface must be machined flat and true on a jointer first
how do you determine the shortest length of material that can be planed on a specific planer?
the distance between the infeed and outfeed rollers so that the leading edge would be gripped by the outfeed rollers before the trailing edge is let go by the infeed
what is the minimum size of drill press capable of boring a hole through the centre of a piece of material 380mm 15" in diameter?
a 15" drill press are measured to the centre of the chuck to the column so the drill press is only capable of drilling a whole in the centre of material 7 1/2" from the column
explain how to change speeds on a drill press equipped with step pulleys.
while stopped the tension is released on the v belt than it is moved manually to different positions on the pulley
why would you clamp the long end of material to the left of you when using the drill press?
put it to the left so if it comes loose it is taken into the column rather than the operator
what hold the abrasive paper on a disc sander?
it is glued to the metal disc surface
which part of the sanding disk is used for sanding?
only the part rotating down
what is the benefit of cleaning the abrasive belts and discs on your sanding machine?
the lifespan of the belt or disc can be greatly increased
the tool rest on the grinder should be positioned no further than 3mm 1/8" from___
the abrasives wheels edge.
why is overheating the edge of a cutting tool while grinding a problem?
because if it is over heated it destroys the temper
