John, for the best results router bits need to be run at the speeds they are designed for. You can easily build a jig so you can make your cuts with a router. Another option would be to contact Onsrud about a milling bit designed for the speeds you run at as well as the material you are working with. I was going to contact Whiteside about having a bit ground to the size you need but they are on their annual vacation shut down this week.
