1. What are the four basic steps in building and covering a flat?
2. What tools are used in flat construction?
50' Steel Tape
3. Which saw, a radial arm or a table saw, is best for ripping lumber?
Link to an excellent Web Page on the safe use of a table saw.
Steps for ripping a piece of wood with the Table Saw
- Set the rip fence for the desired width;
- Put on your safety goggles;
- Turn on the table saw;
- Gently push the wood through the saw, let the blade do the cutting;
- Make sure the wood is tight against the fence;
- Without letting go of the wood, pick up the push stick when the end of the piece of wood reaches the edge of the table;
- Use the push stick to gently push the wood completely through the saw
- Turn off the saw; and
- Wait until blade stops spinning before removing the scrap.
For cross cutting?
Radial arm saw.
Link to an excellent Web Page on the safe use of a radial arm saw.
Steps for crosscutting a piece of wood with the Radial Arm Saw
- Put on your safety goggles
- Hold the piece of wood against the fence with your left hand (if your are right handed)
- Turn the motor on;
- Grab the handle with your right hand (if you are right handed) and slowly pull blade through the wood;
- After the cut, push the blade back behind fence;
- Lock the blade in place;
- Turn the motor off; and
- Wait until blade has stopped turning before clearing the scrap off the work bench,
Another major power tool commonly used for cross cutting lumber is the miter saw. It is fast and accurate and can be also used to make miter cuts in molding, The miter saw has replaced the radial arm saw in many small scene shops.
Steps for crosscutting a piece of wood with the Miter Arm Saw
- Put on your safety goggles
- Hold the piece of wood against the fence with your left hand (if your are right handed);
- Grab the handle of the saw with your right hand (if you are right handed);
- Turn the motor on by pullin back on the "trigger;"
- Slowly push the blade into the wood;
- After the cut, release the "trigger;"
- Let the saw return to its upright position;
- Wait until blade has stopped turning before clearing the scrap off the work bench.

saber, or jig saw?

5. What power tool is used to "drive in" a dry wall screw?
A cordless drill with a #2 Phillips head screwdriver bit.

7. What additional tools are used in building, legging and assembling a platform?
8. What are the primary tools used by the production electrician?
9. Which hand tools have the highest disappearance rate?
10. What type of wood is normally used in flat construction?

11. What is the actual width of a 1x4?
3 1/2 inches.
12. What is a board foot?
A piece of lumber which is 12" wide, 1' long and 1" thick. By definition, a 1x12--1' is one board foot. 1x stock is normally priced by the board foot so it becomes necessary to convert linear (or running) feet into board feet to determine how much your lumber order will cost.
What is the formula for converting linear (or running) feet into board feet?
(Linear_feet * Board_width_in_inches) / 12 = Board_feet.
Enter the number of linear feet of lumber needed, Select the size of lumber (1x4), and Click the Calculate button.
13. How many board feet are there in 1-1x12--16'? in 1-1x4--12'?
14. If #1 grade white pine is $4.21 per board foot (in September 2007), how much would these two pieces of lumber cost?
15. What size lumber is traditionally used for framing stock and supporting legs in platform construction?
16. How is 2x4 stock priced?
By the running foot.
17. At $.46 a foot, how much would 20 pieces of 2x4-16' cost?
18. How, and where, is plywood used in the theatre?
3/4 inch, 5 ply, plywood is used as the flooring in theatrical platforms.
1/4 inch, 3 ply, plywood is used to "profile" a flat and as corner blocks and keystones in flat construction.
19. What is Luan and how is it used?
Luan, also known as Philippine mahogany, is an inexpensive, thin (1/4") flexible, 3 ply, plywood commonly used to cover hard flats.
20. What is the standard size of a sheet of plywood?

Int -- The glue which holds the layers together is water soluble (designed for interior use).
AD -- One face of the sheet is excellent (A) and the other side is poor (D).
