Excellent job. I’ve made several different designs and your method of doing the channels is by far the quickest!

I actually made three – the first used dovetail ways and slides – to much binding, the second is the square channels but I needed to make a smaller one to get to the size oval I need. The one pictured represents the smallest I can go with the router. I might be able to go a bit smaller if I were to make a clamp to hold the router motor but for now, this is fine. One lesson learned is to drill the holes with a slightly undersized bit for the trammel holes and the slide bolt holes – The tighter the better for a smooth oval.
