My Grandpa was quite a woodworker. The only saw in his shop was a radial arm saw. So, when I began to outfit my meager little workshop, that's what I bought, despite much advice that I'd be happier with a table saw.
Yesterday, I needed to cut out some perfect circles. After reading of various complicated jigs which one could build to do the task with a band saw, a router, or a sabre saw, I figured out how to do it here. Necessary equipment? One nail. Thanks, Grandpa!
