Lucas Contreras's router pantographLucas Contera, from Andalucia in Spain, sent me some pictures and video of his router pantograph machine.
Lucas doesn't speak English, and I don't know Spanish, so I had to use the Google Translate to communicate. Google's translator works surprisingly well, and can translate whole webpages. For example, here's this page in Spanish or a language of your choice by google translator.
I really like the simplicity of this machine. Much simpler than my Pantorouter. why didn't I think of that? But there's a lot more that the Pantorouter can do.
Lucas built his own plunge base for the router.
The problem with normal plunge bases is that two hands are needed to operate them. Also, the old base didn't allow for a deep enough plunge through the work table.
The hardest part was ensuring that the router was always perpendicular to the work table. This was solved by making the router mount slide on two 60mm long bronze bushings.
