Looking good Sparky, CRS must be a northern hemisphere version of CRAFT?
Is heads off and between the bottom rails the only way out for the motor?
Thought you mentioned some removable rails.
I'm making up some joiners for removable rails, basically a split piece of solid with 2 shoulder bolts that is spigoted into the rails.
If you have removable rails could you post a pic of your joiners please?
