Posted on January 18, 2017 by robertwilkie

I like this one better than some, its more portable but…the downside its at one height for now (2×4 height) so its not really adjustable except via the router itself. http://www.instructables.com/id/How-to-Use-a-Router-Planer-Surfacing-Jig-to-Thickn/

Another nice build for hand based chainsaw
