Thanks James, I'll probably mess around with it at my house this weekend and if I need further help I'll contact you.
I called several garage installers and they all said the same thing.. Wood doors require too much precision in the way they link with each other and it would be nearly impossible to fabricate a panel. In fact, they laughed when I asked. Well, someone had to make it at some point, lol. Is it really all that difficult or would they all just assume you bought a new one?
You have a plan. Good luck with trying!
The folks you spoke with sell doors, if you are paying their hourly rate for labor, you are probably better off buying new doors. If you can pull it off and make them work on your own, you will gain another bunch of years out of your efforts. They told you..."the way they link with each other" it is all in the hinge. While you can replace the hinges, you will most likely reuse them. Try one panel and see how it goes. Next scenario if it doesn't go well, you park your vehicles in the drive for a week and make the drive next Saturday morning to take advantage of the generous offer to help building two panels and install them on Sunday. Absolute worse case is you reassemble the door and order two new units install the following weekend. Should be done in two weeks at the extreme.
Just be careful with that stored energy in the springs. It could hurt you bad!
