Help With Exterior Door Frame And Hinges
I plan on welding my stock school bus door halves together and putting a lock on it so it acts like a regular door. However, I don't know the best way to go about building a door frame.
The door is 86 3/4" tall, 27" wide, and 1 1/4" thick. The door opening is 85 1/2" tall and 32 3/8" wide. That in mind, I will either have to widen the door or build a really funky door frame, and either way I will have to shorten the door some. The door originally butted up against the first step rather than fitting over a threshold like a normal door, which I would like to change, as I don't think that's the best way to keep water and bugs out.
Could I just build a frame for the door to butt up against and put a gasket on it, or should I try for a more traditional door frame? How much of a gap should there be between the door and the door frame to keep out water but prevent excessive scrubbing? Should I install the sub floor or door frame first?
The door is also pretty heavy, and I doubt regular hinges would be able to hold it. The hinges would also be exposed to the elements and may rust. What kind of hinges would be best for this?
