Very nice. Thanks for sharing. I really like the use of Plexiglass for the base. I made these little guys for doing inlay work. They're for much finer work than a 271 is able to do. The smaller has a 1/16" iron for getting into the stringing grooves. Both irons are from Allen wrenches.

I have a 271, but of course now I'm thinking about building a couple like this gentleman's with a clear base. Router planes are one of the unsung heroes of cabinet work and not that difficult (or expensive) to make.
