The Construction Master can be used as a stair calculator, to figure rafter lengths, squaring walls, and many more uses. In addition to the special purpose uses already mentioned the construction master can also perform the functions of a regular calculator.
This is the handiest stair construction tool to come along since the framing square. Accurate to within 1/16th of an inch it will greatly speed up and simplify the math involved with stair layout.
After entering the values for total rise, run, and desired riser height the construction master will accurately and quickly display the following information.
8-11 FEET INCH RISE
11- 0 FEET INCH RUN
7 5/8 INCH R-HT
14. RSRS
10 1/8 INCH T-WD
13. TRDS
13- 8 3/4 FEET INCH STRG
36.98 ΒΊ INCL
7 1/2 INCH R-HT
10. INCH T-WD
6- 8 FEET INCH HDRM
Total Rise
Total Run
Individual Riser Height
Number of Risers
Tread Width
Number of Treads
Overall Stringer Length
Angle of Incline
Stored Desired Riser Height
Stored Desired Tread Width
Stored Minimum Headroom
By default the desired riser and tread settings are set at 7 1/2" and 10" respectively. The desired riser height can be reset to a new height if you need it for a special set of stairs such as the type used in nursing homes.
Lets say you need to build stairs with a 5 1/2" rise to reset the desired riser height you would use the following key strokes to enter the new default setting for the calculator. Press 5, inch, 1, /, 2, stair, and the calculator window will display R-Htm 5 1/2. This tool really is that easy to use.
