Build Two Step Stairs

Build your top step as you would for a single step.

Build two step stairs.

Nail the risers to the stringers to complete the steps. Use the narrow part of the square for clamping the riser gauge and the wider part for the 10 1 4 in. Fasten the two frames together with the back framing members flush with each other. Lay out the stairs by drawing on the outside of the square sliding the square along until it meets the last mark to learn how to build steps.

Learn about an old school technique to mark and cut stairs stringers without any specialty tools or calculators. Rip 1 x8 risers to width and cut to length flush with the outside of the stringers. The simplest way to do this is like a toddlers step stool with 2 steps instead of 1. Clamp the stair gauges to the carpenter s square.

All steps must be the same size the rise and run must be the same on every step width of each step must be at least 2 feet 8 inches normal household steps are. 2 steps at 9 66 leaving 9 66 from the second step to the hot tub. Build your bottom step twice as wide as a single step. 29 3 9 66.

Double box steps are built using the same techniques as for a single step. Make the steps 12 deep by 26 5 wide. Add decking on top of your frame. Using two treads on each step minimizes the cracking and cupping that might occur with a single wide board.

I recommend that anyone building a staircase in there home contact a building inspector to inquire about current and applicable fire building code. You will need one box for each step. Also cut one piece of treated 2 x 4 lumber to 3 long. For each stair cut 10 treads from 2 x 10 lumber and 7 risers from osb sheets.

This will create a stair stringer calculator. Cut a notch in the bottom of the stringers to fit over a piece of 2 x 4 lumber making sure to cut the notch in the same place on each stringer. For instance you could cut 1 in 5 in 2 5 cm 12 7 cm boards to the width of the stairs and install two on each step with a gap between them.
