tFUnk,

First I recommend you check out these two forums for some good S/S information.

From them you will find a lot of information to answer all of your questions. I think some things are still getting confused with regards to freewheel vs. freehub/cassette.

Freewheels: They generally are a 6spd or 7spd cogset with its own built in ratcheting mechanism and is one complete assembly. It screws on to a hub clockwise with normal threads that are similar to what bmx bike freewheels use. Hubs that use freewheels that screw or thread on to the hub can also accept a bmx freewheel (not fixed). I did mine using a small spacer on the inside of the freewheel to help move it further out for a better chain line with out messing with axle spacing or wheel dishing.

Freehubs: They typically accept 7spd, 8spd or 9spd cassettes. The freehub is attached to the hub and has its ratcheting mechanism inside the freehub. Upon the freehub is a cassette which is a group of cogs and spacers which may be attached together or may all be seperate. They will use a lock ring that torques down on the smallest cog of the cassette to keep it all together. Many people make S/S wheels by installing a whole bunch of spacers and only one cog properly aligned with the chain ring and lock it all down with the lock ring. In this configuration you have a freewheeling Single Speed.

>when i thread on a freewheel singlespeed cog it will just >unscrew when i backpedal, correct?

I haven't personally tried this but from what I have read people seem to get this method to work quite well.

>is that english bb lockring the same lockring that is holding my >current 7sp freewheel onto the hub?

This is confusing, this makes me think you are using a cassette with a lock ring but you stated freewheel. If your first statement is correct and you are using a freehub than no the lockring on a bottom bracket is not the same as what you are using.

>would a bmx freewheel thread onto a freewheel? do i need a >lockring with a bmx freewheel?

No, No. A bmx freewheel will thread on to a hub that uses a 7spd freewheel but not a hub that uses a freehub/cassette setup. If you use a bmx freewheel on the proper type hub you won't need a lock ring since there will be no need since the freewheel will not be fixed. Hence you could backpedal.

>and when you said redishing, how is that done? is it something i >can do at home or pretty easy to learn? tools? how much tools >cost?

Redishing would only be required if you change the spacers on the wheel to adjust the chain line. This would then cause the wheel to sit closer to one side of the frame. To redish the wheel you would have to loosen the spokes on the side that is closest to the frame and tighten them on the other side to make it correct. This would all be done methodically like 1/2 turn loose one one side and 1/2 turn tight on the other and recheck for proper alignment. Continue this till it is good but maybe drop to 1/4 turn each side.

BMX freewheel should cost about $20 but I don't think that is what you need.

Finally take a look at this page on Sheldon Brown's site. It has some good pictures which should clarify the freehub/freewheel debate and cassette confusion.
