Hi dcorb
Was wondering if you got the air brush to work on the cnc if u did could you post a idea or pics I think it's a really cool idea thanks

 

Great build, I'm planning for a smaller 15" x 24" base, of 2" square tubing.
-Are the allen bolts just threaded into a tapped hole in the 2"x2" tubing, or is there a nut inside the tubing?
-How did you get the welded base flat/co-planar? I'll MIG weld mine, using the welding wire-gap trick to make the angles close to 90 degrees, but the flatness/warp of my base is a concern.
Thx
