What's the simplest way to make mortises with a router? I've got 24 holes
that need to be cut on 2" legs for my current project. I've found several
commercial jigs for sale but they're pretty pricey. For a few buck more I
could buy a dedicated mortising machine. It's is on my list, but not at the
top.

Any pointers to homemade jigs/plans that you've used and work well?

Thanks,
Larry
