I just had new engineered hardwood floors installed, but the installers said they don't cut doors, and one door is hitting a t-molding. I'd like to shave the bottom of the door so it doesn't hit the t-molding, and I prefer not to take the door off the hinges. Plus, I don't own any kind of power saw. Is it possible to sand/shave it while it's still hanging on the hinges and without using power tools? There's about 1/8th of an inch gap under the door when it's not hitting the t-molding. I was thinking of putting a towel down on the floor (to protect the floor), laying a thin piece of wood on it, and then placing sandpaper on top of the wood so that the door will barely be able to pass over the sandpaper, and it will sand it a bit by moving the door back and forth. But I was wondering if there was some kind of sanding tool that could make this easier. I was imagining a rubber belt that has sandpaper on one said and smooth on the other and putting that under the door and pulling it along the bottom of the door or something like that. Thanks!
