How many stringers are required in a residential stair 1200 mm wide, if it has open risers?

3
CODE
9.8.9.4

3) Required exit stairs and public stairs serving buildings of other than residential occupancy shall have a width of not less than the greater of a) 900 mm,

In this case, since 1200mm is greater than 900mm a third stringer is required.
If they had closed risers, then 1200mm would be ok with just two stringers

At what height must a handrail for stairs be installed?

CODE
9.8.7.4

Handrails must be installed at a minimum height of 900 mm (35.4 inches) above the stair or ramp nosing.

The maximum height of a hand rail should not exceed 1,070 mm
(42.1 inches).

These measurements are taken vertically from the tread or landing nosing to the top of the handrail.

Handrails require at least 2″ of clearance (the distance between the edge of the railing and the nearest wall).

In most cases, handrails must be continuously graspable throughout the length of ramps and flights of stairs – from the bottom riser to the top riser.

What is the difference between open and closed grit sandpaper?

how much of the surface area is covered with abrasive grains. Open coat abrasives are less densely packed with grains compared to closed coat abrasives. Open coat abrasives are better for sanding softer materials like cedar, pine, aluminum, and brass. Closed coat abrasives are better suited to sand harder materials like oak, hickory, and steel.

Choosing the right sandpaper? A: heavy sanding and stripping B: smoothing surfaces and removing small imperfections C: to finish surfaces smoothly D: painted surfaces, requiring sanding between coats

A: coarse sandpaper grit measuring 40- to 60-grit B: choose medium sandpaper from 80- to 120-grit sandpaper. C: use a super fine sandpaper with 400- to 600-grit D: 220X ( x is grit)

When using a router, the bit will pull itself into the cut if you travel

From left to right When routing the outside edges of a frame or a panel, move the router in a counter-clockwise direction. If you are using the router on an inside opening, move the router in a clockwise direction. On a router table you move the stock rather than the router, which is suspended upside down under the table

When looking straight down at the top of a router, the bit rotated in which direction?

When looking straight down at the top of a router, the bit rotates in a clockwise direction. That means you should move the router from left to right, but—and this is important—that's only true when the router is positioned in the middle between you and the workpiece Ex if you are routering out a window If it is an electrical box ( routering out the outside) would be right to left

If a table saw coasts for only a short time after it is turned off, the problem could be?

B: Two stop blocks

There are ___ types of Dados and a_____?

3 types of dados and a rabbet Through, stopped and blind 1: Through The through dado joint is the most common type of dado joint and involves cutting a groove that spans the entire width of the workpiece. 2: Stopped dado A stopped dado joint, as the name suggests, is a groove that does not extend across the full width of the workpiece. Instead, it stops before reaching the edge. 3: Blind dado (half dado) Rabbet A rabbet joint has a groove or dado cut along the wood edge or end, so when the second wood piece is fit into the groove, the long side is flush
