Speaking of Van's Air Force; buying a tail kit for the RV of your choice will give you a very real idea of what it takes to form, cut, drill, and rivet aluminum sheet. If you do a decent job of fabricating the assembly, you can most likely resell it and make back a fair portion of your initial investment. This will give you a chance to acquire some of the basic tools for metal fabrication, and work on a small project that you can control and work at your own pace. It will also give you a chance to make acquaintances with other fabricators in your area, as you'll probably need someone to help you buck those rivets!
Also, if you can make it to EAA AirVenture in Oshkosh, you'll have the opportunity to try your hand at fabric, welding, etc, all for the price of the ticket at the gate. Its a week-long event that will offer you the opportunity to cross paths with droves of like-minded people.
Baby steps, real world experience, and education. After a few years of focused effort, you'll be surprised how much knowledge you've gained, and the skill sets you've acquired! Pad that resume with experience, focus on quality, and then when Vulture's Row Aviation or one of the other companies comes around here advertising for experienced help in their warbird shops, you just might have the resume to make your dreams for a career in warbird fabricating come true.
