The LowRider 4 changed my way of building skis. I have been looking for a long time for a CNC long enough to work with ski length and narrow enough to fit my basement. The LowRider 4 is definitely what I needed and I recently included a laser module.
Here a few pics of my build in action:

Cutting the base with a drag knife using a vacuum bed done with a 3d printer
Here you can see the finished product if interested:
I’m sure the forum will have many questions about your build and your skis. Looks great.
Please post them in “things you’ve made”. 
Would really love to see them, not on Instagram.
As requested

As requested in an another post I am providing more details regarding the Dragknife base cutting.
I use a Stepcraft Heavy Duty Drag Knife with Martor 52 blade at the topmost position (offset 3.03 mm). As it is a PITA to have to insert the knife in my Makita because I need to change adapter size and unscrew everything I created a 8 mm to 65 adapter that fits in the Makita mount of the LR4.
If needed you can find the adapter here: Dragknife Adapter
It is critical to keep the base down with a vacuum table. As I did not want to build a full fledged vacuum table I built one that I can easily add and remove from the LR4. It is 3D printed and uses 20x20 modules that can be combined in one direction. I use a 2 m long for the base. I also have a 40 cm long for cutting the cork sheet. You can find it here: Vacuum table
To cut the base I cut with 0.4 mm steps. I use the dragknife dressup available in FreeCAD CAM module.
Happy to provide more details.
Haha, you just have to pinch your nose to shield you from the “Meta” smell, and take a dive into instagram as all the other maker kids do 
What software do you use to generate gcode for the dragknife?
I use FreeCAD CAM module to create the path and then I apply the Dragknife dressup available in the same module.
