Small Machining Vise designed around 20x80 Openbuilds Rail System

I'm conducing guitar loudspeaker cabinet fabrication technique research (material type/thickness, mechanical joints, adhesives, etc) and how these relate to cabinet/speaker coupling and enclosure resonance with respect to psycho-acoustics. Basically, does one speaker cab sound better than another and why?

Integrating custom machined components and off-the-shelf CNC components to create a portable diode laser etcher with air assist and reasonably substantial z-axis travel.

Gantry style rigid build

The Ronin OX is a dedicated fiber composite milling machine. I give a complete in-depth article on how to take a nearly stock OX build and easily turn it into something that can mill carbon fiber and G10 plate effectively and quickly.
