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

CODE
At what height must a handrail for stairs be installed?

A

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.

Q

What is the difference between open and closed grit sandpaper?

A

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.

Q

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

A

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

Q

There are ___ types of Dados and a_____?

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

Open valley:
• Consist of a metal valley pan (flashing) between “open” ends of shingle runs on either side

• Usually more expensive to install because of metal cost
• Protected from degrading over time due to no risk of granule loss on the shingles

Closed valley:

• Created by running the shingles from one slope underneath those from the adjacent slope
• Acceptable water-shedding ability
• Usually cheaper to install
• Subject to degrading over time due to granule loss where shingles overlap or where water runs along valley
