Hi & welcome fellow ford fan.
After building my own 8" reflector some years ago, including making the main mirror, I wouldn't bother these days. I would definately make everything except the mirror though....much cheaper. I feel the prices of mirror's to buy are well worth the money.
I spent at least 3 months making the mirror & the testing equipment. The end result was a pretty crappy mirror...had a turned down edge & we didn't polish it properly. One of the most frustrating things was getting one piece of 80 grit in the 120 grit grinding......GRRR!.. I ended up selling the mirror & buying a replacement.
I'm not trying to talk you out of making your own by any means! I commend you for having a go.
Good luck.
