This is a new kind of Router lift mechanism.
We've seen so many things on that topic, sometimes very complicated contraptions, with screws, slides, or sometimes gears.
They often have several drawbacks, like heavy footprint, limited access to the chuck, intrusive, see destructive for the router, etc ...
Sometimes, the pulling action applies only to one of the router posts, which works well at the beginning, with plenty of WD40, but stops working after some hours because of wood dust.
This mechanism fixes all of these drawbacks.
And it is very simple, I took maybe half a day to make it.
It's based on ... bicycle break cables !
And it is really powerful, I can prove it, in my case, it lifts like a charm a router "beast" made for carpenters, German made, which weights maybe 15kg !
Here it is on my site : https://www.labellenote.fr/articles....=313&tconfig=0
