Building the Steps:
Step 1: Make a simple template in order too mark out on the stringers,
The tread positions.
This is a relatively simple task, take a piece of cardboard 300mm (12") square or
larger (alternatively you can use hardboard, thin plywood or anything similar).
From the cardboard cut out a triangular piece as shown in the following diagram. fig. 3
Step 2: Lay out the two stringers 250x50 (2x10) flat on a couple of saw stools, on even ground or
on the floor.
Hold the cardboard template, with its longest edge flush to one edge of the stringer,
approx 300mm (12") in from one end, and pencil mark around the template. Repeat this
action five times on each stringer, as shown in the diagram below. fig. 4
Stringer 1 must be marked mirroring stringer 2.
step 3: To continue marking out for the treads, use a piece of lumber about
600mm (24") long, and the same thickness as the treads which is approximately 46mm (1 1/2")
This piece of timber is to be
used only for marking and can then be discarded.
Hold this piece of lumber flush on one of the tread pencil lines marked
on the stringer.
Mark each side of the 46mm (1 1/2") thick lumber across full width of the stringers, as on fig.5 below.
Repeat this action to all tread lines, on both stringers to get an effect as in the
diagram below. fig.5
