I still think it's a good idea

Luke: I'll show you how to do it in person when the time comes. For that particular part you'll probably have to export it from the CAD program as an STL and import into whatever CAM program you choose...
No disrespect. But well all don't have a very good friend like Jonathan to fall back on in the early teething stages.

if I could afford it I would go to night school

I know my son Luke would and learn from a video as that's all he does (watch youtube LOL)

however I know he is going to learn a lot from Jonathan as he looks up to him as a expert and a teacher.
