Step 7
The risers are put on next.
These two pieces will
make the step stool much
more rigid because they
will further tie the two
side pieces together. If
everything has gone well
to this point the risers
should fit in between the
two sides. Set the top step
on the sides and measure
the width that the risers should be. If they measure less than 5 ½” you’ll
have to take some off the width of the riser. Test the fit of the risers and
trim the width and length if necessary.
Set the front riser back from the top edge of the sides 1 ½”. This will give
more room for feet on the bottom step. The back riser should be set back
¼”. The risers need to be perpendicular to the step below. The best way
to determine this is with your speed square. After the risers are squared
up to the step, place a pencil
mark along the sides. Next, with
the combination square, place
marks down the sides to show

the sides.) Just as with the
screws for the side pieces, drill
pilot holes and then drill larger
holes for the screw heads.
