Building a Wood Ladder
This is a simple project that should only take a couple of
hours to complete.
Start by clamping the two 12' - 2x4's. The rungs are notched
into the 2x4 upright 1-1/8" so we need to mark out notches. The
top and bottom rungs are 8" from the ends. This is the top of
the upper rung and the bottom of the lower one. Offset these
marks 2-1/2" (the width of the 2x3 rungs).
Now measure out for the rest of the rungs. Lay your tape measure
on the 8" mark made earlier and measure 16" increments. These
marks represent the center of the intermediate rungs. Offset
these marks 1-1/4" on either side.
Square off the marks you have just made down the face of the 2x4
uprights. Square your marks across the top edge of the uprights
as well.
Now it is time to cut the notches. Set the depth of your
circular saw to 1-1/8". Start by making the cheek cuts of the
notch then proceed to make a series of cuts about a 1/4" apart
through the rest of the notch. Do this for all the notches.
Before removing the clamps use your hammer to break out the wood
in the notches and clean up each notch with your chisel.
Unclamp the two uprights and set them aside. Now cut all the
2x3's into 19" lengths. Each rung is attached to the upright
with exterior wood glue and deck screws.
Now attach them to the uprights starting with the top and bottom
rung. Put some of the exterior wood glue into both notches and
insert a rung. Make sure the rung in flush to the outside of the
uprights. Secure in place with 4 deck screws. Continue this for
the reminder of the rungs.
Protect with paint or stain and this ladder will last for years.
