I bought my bar jig at the Home Despot for jig saws. The mechanism for attaching the bar to the saw is really lousy, the vibrations from the saw and cutting would cause it to move. Really useless. So I drilled a hole in the bar and used the plastic handle as a stop for the saw. I put the step drill in the stop bar where I drilled the pivot hole to highlight the hole and to illustrate how the jig works.
