I have designed and built a machine inspired by the LowRider that is dedicated to light work. It incorporates the needle cutter for foam and will carry a pen or vinyl cutter. I was going to try and use Ryans parts, but ended up starting from scratch in Fusion 360. The goal was for the cheapest possible machine to cut out foam board model airplanes.
The fixed y-axis rails are adjustable for various thickness of spoil boards/vacuum pads. The z-axis has a 35 mm travel. The x-plates are adjustable for 3/4"-4" table thickness. I am using a 32" door which provides a 25"x70" cut area.
Here is the detail of the y-z carriage with integrated needle cutter.
And the end plates.

The dxf for the plates was updated to use the 60mm rollers available on this site vice the 69mm wheels from my cheap skates that I have been saving for this project since 1994.
Thanks for the idea.
