Just for clarification:
I feel like if the linkage parts don’t interfere with the router then there is no advantage of the 3-Bar Top Mount over the 3-Bar Balanced. The 3-Bar Balanced is probably easier to layout mounting points on the sled but I don’t think that’s a big deal with either one. 3-Bar Top Mount is also currently untested, but I think it’ll work the same.
I will try to build physical tests tonight or tomorrow. I have to balance work and family too!
Thanks for making this brainstorm so productive!
