old FALCON LIFEI CO. sprocket disassembly
I have an old sprocket off of a 1970's Ultra 10 speed road bike. I was able to get the sprocket off of the axle, and want to disassemble it in its entirety to gain access to the cogs. It has a 12 tooth cog on the top, which means the lockring is behind that (I think).. Disassembly by destruction is fine with me.. Don't have a chainwhip, just a basic set of tools and chainbreaker. Any advice on how to take it all apart?

When you say "sprocket," I assume that you are referring to a 5 speed freewheel. The freewheels individual sprockets are manufactured as one whole unit and are serviced as such. Attempting to remove the individual sprockets from the freewheel assembly will render it a useless pile of junk.
What is it that you are ultimately trying to accomplish?

I may have led him slightly astray on this one. If it's a 5 speed freewheel, wouldn't that require a freewheel tool? I told him chain whips, but it's been a while since I worked on anything that old.

I'm not sure. I don't fully understand his post. I read it as he had already removed the freewheel assembly from the hub. I'm assuming freewheel rather than cassette & freehub due to the vintage of the bike.
If the freewheel assembly is still on the hub, then yes, he will need a freewheel tool to unscrew it from the hub.

this sounds like a job for a plasma cutter and a TIG (excuse me, GTAW) welder.

my what a mess i have made! i originally needed one of the gears off of the freewheel hub, not the individual sprockets (thanks for the correction) but i found what i needed online (building fixd gear from old road bike). to clarify though, i was trying to remove the lockring so i could pull the stack of gears off individually.. i got my LBS (see, i'm getting the lingo down!) to take the freewheel assembly off of the rear axle for me, but the lockring is buried behind the outermost gear so i couldn't get to it.. nevertheless, found a track cog online for under $10, so im all set.. thanks anyways
