I know the feeling. It was all a bit of a puzzle. I Went through so many iterations.
I got mine to fit on an 80mm x 40mm extrusion so you have plenty of room. When you say bearings, you mean linear bearings and rails? If you look at the radial torque specs of the HGR rails, you only need one rail (even for HGR15...) Provided you are not wanting to use it as a router!... Clive's looked nice with a rear mounted motor...
You have a link to Clive's?
\/Edit Never mind, I found it.
