- clear safety glasses or prescription glasses
I should ensure the table saw is completely powered down before making any adjustments to my setup.
true
to set my initial height on the surface planer, I should do the following:
1) Make sure the machine is not running
2) Release the brake and raise the cutter so my stock slides easily under the head
3) Place my stock in the middle of the table
4) Power the machine on
5) Slowly lower the head until my material self-feeds
6) Lower the head a 1/4 turn, lock the brake, and start feeding my parts through it
true
We will use the tablesaw to crosscut our material
false
I need to wear safety glasses while working in our lab.
true
We will use the radial arm saw to crosscut our material
true
When using the radial arm saw, my left thumb should be ___________________________.
tucked into my palm to keep it away from the blade
While cutting on the table saw, your left hand is applying pressure to keep material next to the fence. Where should that hand be positioned?
close to, but no in line with the blade. This hand should stay stationary throughout the cut.
I should flip my parts after each pass in the surface planer due to internal stresses in the material.
true
The person in front of me always sets the machine up properly.
false
All of the equipment in our lab has a Sawstop braking system
false
First aid kits are located on the front desk and the cabinet by the sanding table.
true
The number one cause of injury in a woodshop is ______________________.
material kickback from a machine
The Sawstop monitoring technology watches the blade until it has stopped spinning, not just until I push the paddle in on the control box.
true
I can remove the blade guard on the table saw if I think it’ll be in the way for my cut.
false
I can take a 1/4 turn depth of cut on the surface planers.
true
the grey insert on the radial arm saw and the red/black inserts on the table saws are ________________________.
safety zones where I shouldn’t have my hands while using the machine
When setting the fence location on the table saw, you should measure ______________________________.
between the fence and the inside of the blade.
the radial arm saw blade spins so the machine will
self feed toward the operator if not carefully controlled.
The height of the router bit should be
just high enough to cut through the top of the material
Select all that apply. The upper guide on the bandsaw is used to:
- act as a guard to keep too much of the blade from being exposed
- assist in keeping the blade straight
when using the router table, I should feed my work _______________________
right to left
The router table has an automatic braking system installed in case of an accident.
false
Bandsaws are used for precise cuts
false
Bandsaw blades are flexible and can distort while cutting if improperly setup.
true
The bearing on the router bit is used to ______________________.
guide the template or fixture to reproduce the correct geometry
The bandsaw has an automatic braking system installed in case of an accident.
false
while removing large amounts of material on the router table, I should take ______________.
multiple shallow cuts to help reduce blowout.
The shaper has ____________________ compared to the router.
higher torque, less speed (rpm)
We use a fishmouth push stick for the glue blocks for what reason?
it keeps our right hand further from the blade
Why did we use a riving knife over a full blade guard on the glue blocks?
the width of our cut wouldn’t allow the push stick to pass between the fence and the blade guard
A riving knife is more safe than a full blade guard.
false
The Kreg machine is used to create counterbores for pocket screws.
true
The stop on the drill press should be adjusted so that the drill doesn’t pass all the way through the tooling base.
true
The downside of the fishmouth push stick is ____________________.
it requires more downward force from your forearm to keep workpieces on the table compared to our normal push stick.
Countersinks are used to ____________________.
recess the screw head, but not remove enough material to weaken the part.
When drilling through a workpiece, the workpiece should be held or clamped to the machine table.
true
The drill bits will sometimes deflect while drilling, so we used a drill bushing to keep the bit straight.
true
A riving knife is used to:
help reduce table saw kickback
To clean up glue squeeze out, I should use ________________________.
a damp paper towel to wipe down the surfaces while the glue is still wet.
We have a working time of 30 minutes before our wood glue starts to harden.
false
The miter saw is similar to the radial arm saw, and the same safety rules apply
true
All used stain rags should go in ____________________.
the red fire resistant bin in the stain room.
How much wood glue should I apply to a product?
