Singlespeed & Fixed Gear - Dura-Ace Freewheel hub ok?

I was digging through my pile-o-bike-crap and dug out an old Dura-Ace rear hub from the late 80's or early 90's. It's 32H, and has the olde-skool threads for threading on a 7spd freewheel. What are my options for getting something to work on this? I can thread on a track cog, but I want to be SS, not FX [at least not yet]. Thanks in advance for all your insightful comments. :)

Buy a BMX freewheel, and you're golden (assuming I understand what you mean). Any freewheel hub'll do the trick, 'cus you don't need a lockring.

I'm super-new to this, so please forgive the dumb questions. I know that regular freewheels typically have the last cog as a lockring-thing, which necessitates the use of two chainwhips to remove, or there's a four-tooth tool which you use to unscrew the last cog. Are there pawls and stuff built into the bmx cogs? How would it coast?

you are just a bit confused. You are thinking about cassettes which go onto newer 'freehub' hubs. The older DA that you have is built for 'freewheels,' in which the racheting mechanism is built into the cog cluster rather than into the hub body. In this case, you can screw any freewheel onto the hub and you are ready to go. Traditionally a 5 or 6 tooth (I suppose) freewheel would have been threaded on, but most SS bikes are built with a freewheeling bmx cog (a tiny racheting freewheel with one cog on it.) It will work fine just screwing that thing on (make sure that you don't buy one for the smaller -flop side of bmx flip-flop hubs), but to improve chainline it may behoove you to add some spacers and redish the hub.

r-dub means "redish the wheel," of course.

and i am officially up too late.

but you, mr. pinkrobe, are good to go.

yeah, what he said...and it's not that late!

Just to clarify: What you are describing with the last cog as the lock-ring thing is how typical cassettes for freehubs attach, the more modern offering. What you have is a hub that takes a thread-on freewheel. This screws on with a chainwhip or what-have-you, and unscrews with a freewheel removal tool. A BMX freewheel works exactly the same way, only it has just one cog. You'll probably have to redish the wheel, and maybe rearrange the axle spacers to get the rim centered. Beyond that, it's smooth sailing.

Thanks for the help, folks! In my defence, I'm not a complete newcomer to the big world of bikes, but I've never used anything other than cassette hubs for wheels. Now I can build up that hub and pop it onto my road bike, secure in the knowledge that I can run SS. :)
