I made this jig to help in making straight, precise cuts with my circular
saw. The jig is just a base with a small wooden strip across it which acts
as a fence for the saw. The base is purposely too wide to begin with and
then trimmed to the correct size by running the saw against the fence the
first time. After that, wherever you put the edge of the jig is exactly
where you know the saw is going to cut. You simply place the edge of the
jig along your cut line, and clamp the jig in place.
