Since the building currently has no ceiling, I decided to run air compressor hoses to two places in the shop, one to a retractable reel over the assembly table (which can extend 25' and reach anywhere in the main shop room), and another one to a retractable reel in the finishing room.  I've lived with compressor hoses running from a wall-mounted manual reel and lying all over the floor for years.  With these reels mounted to the ceiling, it's a simple matter to grab it, snap on the tool, pull down just enough hose, do the job and retract it back again.

I got a lot of help at Outlet Tool Supply in Atascadero, about 15 minutes from my house. The very knowledgeable salesman helped me choose every fitting and hose right from the output of my compressor to each reel. The system is built with flexible hoses and quick-connects at every joint, allowing me to easily swap in a new hose in case of a leak.

Now that the drywall is in and painted, I remounted the reels and everything is working well.
