# How do you cut ramp stringers?

**cut**triangular

**stringers**based on your rise and slope measurements. The nominal size of the boards you select depends on the

**ramp**rise. For example, 2- x 6-inch lumber could be used as

**stringers**if the rise is less than 5 1/2-inches; a rise greater than that would require a 2- x 8-inch board.

Likewise, people ask, how do you cut ramp joists?

**Cut Joists** The top of the board should align with the bottom of the building. Using a torpedo level, mark a vertical line on the 2x8 (Image 1), and **cut** off a small piece with a circular saw (Image 2). **Cut** three more 2x8s using the already-**cut** 2x8 as a guide.

Subsequently, question is, how do you calculate the slope of a ramp? **Calculating** the **Slope** Divide the length of the **ramp** by the height. This will be the second number in your ratio. The first number is always one. If the **ramp** measures 12 feet long and the rise is 2 feet, you would divide 12 by 2 to get 6, and your ratio would be 1 to 6.

Consequently, how do you build a ramp over existing steps?

**Anchor the ramp over the stairs using 4-inch screws.**

- Extend the measuring tape from the top of the doorsill to the ground beyond the lowermost step to help determine the angle or rise of the ramp.
- Cut three sheets of 3/4-inch plywood to the desired length of the ramp using a circular saw.

What is the proper angle for a ramp?

Maximum slope for hand-propelled wheelchair **ramps** should be 1" of rise to every 12" of length (4.8 degree **angle**; 8.3% grade). Maximum slope for power chairs should be 1.5" rise to 12" length (7.1 degree **angle**; 12.5% grade). Minimum width should be 36" (inside rails) - (48" is ideal).
