I do not use 8mm because the parts are not available locally.
Ebay is the closest supplier for me.
I use thats dax sprockets or sick bike parts and dax or fancy scooter drive sprockets on strong bmx chain .

Therte are #25, 8 mm, bmx, and 410 setups . On one bicycle I use a 410 Diamond chain to keep it from snapping the chain LOL

I hope this leads you in the right direction.
The two piece rear single speed hub chainring setup will alow a large range of sizes.

Thanks

This can be used to attach a sprocket or pulley to work as a freewheel?

YES it can. The sprockets can be 120 ,96, 72 teeth just make sure that everything uses the same chain.

I use sick bike parts freewheels and sprockets because they can use bmx chain.http://www.sickbikeparts.com/catalog/index.php?cPath=21

The thread on freewheel adapter will work on a freewheel hub.
Check here to see if you have a freewheel or a cassette.

A slightly redneck technique that I have used successfully is to use a 18 tooth freewheel and bolt a standard kit sprocket to it. The holes on the 18 tooth freewheel line up with the nine holes if the kit sprocket. I usually use 3 5/16 bolts and haven't had any problems. One has about 1100 miles so far. This will give you a choice of 36-40-44-48-56 tooth cogs, whatever is available.
