Many builders use a transit to make accurate angle and distance measurements.Certainly designing and building stairs with uniform tread depth and riser height over rough ground like that in our photo (left) can be a serious challenge. You can do this using a transit, a protractor or other angle measuring tool either by placing your angular measuring tool on the sloped surface of the stringer side a, or by actually measuring the angle formed between side a and a horizontal or level surface. Typically we use our stringer 2x lumber (before it has been cut to length) for this purpose since by definition the diagonal stringer will be longer than the horizontal stair run. I would just fix the stair riser itself on the stringer. This will allow the tread to be removed without additional damage. I use a good construction adhesive to glue the riser on.
