When gluing up a solid panel from individual boards what should be the maximum width of an individual piece be?
Depends on species, but harder woods can be 7” wide
When gluing up a solid panel from individual boards why should you alternate the grain on each?
to help minimize panel warpage

How much thick of a layer of glue should you spread on a glue joint?
1/16”
After gluing the top up and you have set it off the table, why should you stand it up where the glue joints are vertical?
So the glue will run down the joints not across it
Which one of the two common types of lathes form small shops or home use?
Standard
What is the name of the specification of lathe will determine the largest diameter that the lathe will turn?
Swing
In relation the the center or a spindle turning where should the tool rest be adjusted to?
1/8th of an inch away from the turning and 1/16th to slightly above the center line
What additional accessory is needed for outboard turning?
Turning stand
Turning between centers is called what type of turning?
faceplate turning
What should be used to remove the spur center of a lathe?
knock out rod
When gluing a backer block to a piece to be turned as a faceplate what type of paper should be used
File folder paper
Explain how you can make a mortise and tenon joint one that can be taken apart.
Assemble the joint without glue and drill one or two holes through the frame and the tenon and cut dowels to go in the holes and don’t glue them either
Why is it so important for your framing members be 3/4 thick?
it is not as easy to make tenons the correct size with wood of different thickness
Which is not a typical size of mortising chisels?
7/16th
Why should you make a mortise 1/8th deeper then the tenon is long?
so that when you put glue on the tenon you will not get a “hydraulic lock” by glue getting under the end of the tenon
What can happen if you don’t drill the ends of a mortise first?
the end of the mortise where you finish will be slanted because the chisel will flex
What can be applied to the mortising chisel to make it go into the wood easier?
bee’s wax
Why might you use a blind dado rather than a through dado to mount a shelf?
It hides the joint
What is the name of the lap joint where the two components meet at an angel other than 90 degree?
oblique
Which wood wafer used in plate joinery is 15 mm wide and 47 mm long?
0
To remove the nut on the oliver table saw to take of the blade which direction do you turn it?
Clockwise
Which is not a one of the three different types of dado blades that I explained?
Variable
Which on elf the three are usually not used by professional woodworkers because the blade leaves a slightly rounded bottom in a dado?
Wobble
Which is the quickest way to determine how many chippers to use in the dado blade for certain cut?
Measure the wood to determine how wide you need to make the dado then look at the chart
If you cannot get the correct setting for the dado blade with any combination of chippers what must you use?
Shims
What is the first thing you must do when getting ready to change the blades on the table saw?
Push the stop button on the orange power box at the bottom right side of the saw

Rail
Which component of a raised panel door is as long as the panel is wide?
Rail
How can you use an outside caliper to set the fence for a raised panel router bit?
measure the bearing on the router bit and move the fence forward past “0”, half the diameter of the bearing
Besides unplugging the router, what is another very important thing to do to make sure that the joints fit evenly when installing the router bit to cut the tenons and grooves of a raised panel door?
Do not change the height of the bit once you used the first bit
When putting the 1/4” collar in the 1/2” chuck on the router table what must you do to get the collar to fit correctly?
Make sure the slot in the collar lines pup with the mark on the chuck so that it will fit over the “O” ring
Why is it necessary to slow the router down then “raising” the panel of a raised panel door?
So that the possibility of over speeding the bit is not a concern
How many turns of the lift crank on the router table will raise the bit 1/16th of an inch?
Two turns
How do you adjust the speed of the router?
Turn the roller switch on the bottom right side of the router
When using the dovetail jig which drawer component is attached to the top of the jig?
Sides

you will ruin the guide
Why would you cut the groove for the bottom off the back of the drawer?
to make installing the bottom easier
