Hi Captain !
I like this one, I have exactly the same router, but mine is blue and branded by Ryobi. (750 W)
I also use it under the table, and I like your simple lift. I have personally a lift made by a simple screw that pushed upward, applying the tip on the plastic carter, but I think your system is better.
One day or the other, I will do something like this.
Thanks ! (and thanks for the documentation, very clear)
Christophe
