Ravill,
I would not dare putting a 140 on a Bobcat, I have the 120 and will tune it down to 130,000. I also fly at 5280 Ft which reduce the thrust by ~20%
I Have a table top mill from Harbor Freight which I converted to CNC. My lathe is also from HF, it originally a 7X10 but installed the 16" bed.
Sirrom,
I designed the tray in SolidWorks, and Adobe Illustrator for laser cutting.

Glued the wing tubes today with Aeropoxy, I have also installed the flaps and ailerons servos.
