I have a 1940's house, with a swinging door leading into the kitchen. The
door's old, too, maybe original, attached to the frame by pivot pins stuck
in sockets in the head and sill.

I thought perhaps I could depress one of the pins, assuming it might be
retractable, thus allowing me to simply pull the door out, but that doesn't
seem to be the case, seems like the pins are fixed. Therefore, looks like I
have to dismantle the door. Maybe I'm wrong; missing something?

What's the best way to get that door out? Break out the threshold and pull
it out from the bottom? Hopefully, presumably, the bottom pin doesn't sink
down any further. I only wanted to take the door out to move some new
appliances into the kitchen, then put it back in again. I sure hate to tear
it up like that, didn't expect a construction project.

Thanks in advance for any advice.
