ACF: How do I make a tank?

I downloaded AFC a couple of days ago and I’m wondering how to make a tank in it.
I know for the armor plates thickness and how to use them, gun and ammo stuff I need to know how to make the turret of the tank, tracks, all the wire stuff and how to weld the body so it doesn’t destroy itself when I move.

I’m sorry if this sound noobish but I’m not very good in gmod contraptions stuff. I’m more on posing/modelling.

No worries. If you’re into immediate action, join GGG-Novgorod and I’ll give you a live action tutorial, alternatively add me on steam: Satyria

I also suggest you read these threads for a more in-depth perspective on what building with ACF means:
