Turns out I got all my measurements right; as you can see here, the door fits pretty nicely in the jamb, with just about an 1/8" gap:
I had to shim the Hell out of the strike side, and will probably want to stuff some insulation in there, but once I got the jamb in place and got the door on its hinges, everything was nice and square and plumb. Here are a couple shots of the door on the cart:
Next, I took the door off and sawed it roughly in half. I now have a Dutch door, which will be nice in the Summer:
Of course, I'll need to get a knob and a couple of dead-bolts for the door. I also got the rest of the interior sheathing up this weekend. Next step here is to install the FRP and the stainless...
There's a pretty nice view of the Fremont Bridge right out of the garage bay (we also get a lot of trains going by):
One other fortuitous development this weekend was that Steven Shomler, author of Portland Food Cart Stories and host of Tasty Tuesdays on the Portland Radio Project, came by a barbecue I had on Saturday with his radio producer, Ken Wilson. They're interested in interviewing me once I'm almost ready to open. That'll be a fantastic bit of exposure. Many thanks, Steven and Ken! Oh, and thanks as well to Risa Dale for the door, and to James for helping to hang it!
