I'm also in Southern AB, Calgary to be exact.
I also bought the rockcliff plans, as a reference though, and I designed my own machine based on those principals and many other ideas from this site and around the net.
Here's a little bit about my machine sofar.
First attempt aluminum cnc router
doesn't really look much like a rockcliff, but some of the ideas are the same, I was able to use t-slot instead of mdf also.
hope your machine works out well.
