I can take absolutely no credit for the project on this page: all I did was import and sell the saw guide used in the construction. The project is entirely the brainchild of the contributor. Here is what William says about his project:

"I have
been using my “mini” saw guide and am very happy with it.
I managed to cut a small angled piece of wood and added that to the edge of the saw
guide to cut wood at 75 degrees, for example, so I can now cut timber at the
angle I want with my “jig”."
Thanks, William.
