I use most methods except a router but actually that is what the RotaZip really is. I just got one a couple weeks ago and it comes with 1/8" and 1/4" collets so I have already successfully used it with small router bits. In the past, I most often have used a method similiar to what Bob mentioned except I used a 16" Multiplex radial arm saw. I also now have a saber saw mounted upside down that is easier to use but you have to be careful as the cut wants to drift.

Back to the RotaZip, I needed to cut through a 1" piece of very hardwood decking. On that job it did poorly but I was able to get in a tight spot I could not cut with anything else. The Rotazip only cuts to a 1" depth so that was at its maximum. If the Rotabit can push about 1/8" through I believe it would have worked better. In this case I was cutting down to a steel beam, so it can cut to an exact depth. I expect to use the RotaZip for most of my future circle cutting especially plywoods and soft materials undet 1"T.

Good Luck
