First cut happened today!!! Need to make a few adjustments. Like the z height was a little shallow. I didn’t have the T-Slots or Vacuum Pods hooked up yet, didn’t have time. The pinewood derby is next week. My 9 year old drew this up in Inventor and I walked him through the CAM process. I will have a little machinist soon. I will link to his video of the final build when he is done painting. Now I have mine, and 3 other kids to cut. 
For those who want to see my parts list for the build:

It has 2 contoured rails butted together on each Y axis to get the fill 3000mm length, about 120″
For the base, I picked up from my local steel supplier:
20ft of 4″x12″ Rectangular tubing 0.188″ thick
20ft of 4″x10″ Rectangular tubing 0.188″ thick
50ft of 2″x2″ Square tubing 0.120″ thick
and since they had no aluminum I ordered some from onlinemetals.com for the gantry and Z axis, I didn’t want to make the 4 hour round trip so I had them ship it.
4″ x 8″ x 0.25″ 6061T6 ALUMINUM RECTANGLE TUBE – 60″
2″ x 3″ x 0.125″ ALUMINUM ANGLE 6063T52 – 60″
0.75″ x 8″ Extruded 6061T6 Aluminum Rectangle Bar – 36″
0.75″ x 6″ Extruded 6061T6 Aluminum Rectangle Bar – 48″
from boltdepot.com I ordered
1 box of 100 Metric socket cap, Stainless steel A-2, 5mm x 0.8mm x 25mm
1 box of 100 Metric socket cap, Stainless steel A-2, 5mm x 0.8mm x 30mm
3 boxes of 100 Metric hex nuts, Stainless steel A-2, 5mm x 0.8mm
1 box of 100 Metric flat washers, Stainless steel A-2, 5mm
1 box of 100 Metric high collar lock washers, Stainless steel A-2, 5mm
1 box of 100 Metric socket cap, Stainless steel A-2, 5mm x 0.8mm x 35mm
I figured that would be enough to get the rails on, I like to stick with metric when I deal with the rails since they are in metric, and I think it is actually cheaper to buy metric… I dunno, just me
