Awesome idea and a big project. Looking forward to seeing the finished product.I’m making my one-car 1950’s garage a drive-through. I have a huge back yard with a pad in the far corner that could be used as a project area to build a vehicle on but no way to get a vehicle INTO the back yard. When I did a garage rebuild a year ago (?) I made sure that I could fit a rig through, and left the back wall unfinished. So I have been working on that back wall. I now have an 8’ x 8’ opening in the back and will be building a pair of 4’ x 8’ swinging doors to fit. And in one of those doors will be the 30” door that I removed. That’s the plan anyway, I have a piece of steel and an idea on how to make the frame rigid. The idea is that the big doors will stay closed most of the time ( all the time in the winter) and my day-to-day access will be through the small man door. And when I need to move a vehicle through, open the big doors. Here’s a link to the “ whatcha up to “ thread where I posted my last pic.
