LAMO!
1: want to learn to weld. Great, it takes skill and practice/ not an overnight process.
2: Than you want to make bumpers, rock rails, etc. Do you have any idea on how to design, CAD, properly support these new accessories?
3: You haven;t priced material yet. soooooooo, i'm assuming youhave no idea what materials are even needed to make the products.
I'm going back out to my garage to make a deisel/ hydrogen, LP, gas burning kit to slap into my motorcyle that I can convert into a hang glider.
I thought you were buying a Bentley. Yoou should start your auto mechanic trade so you can afford to maintain that first.
