Fixing a Sturmey Archer AW hub is on my list of things to try in the near future. You need one that was manufacture after 1962. You end up with a direct drive and a 25% reduction as well as a nuetral. From what I've read there is a lot of slop in the system that feels like a loose chain, but it's the insides of the hub moving around until eventually it breaks. There is a more refined conversion process where you fabricate a new clutch plate which tightens up the whole works so it feels more like the old ASC.

The last two or three ASC models I saw on eBay went for around $400. The shifters go for almost the same.

fixing an aw doesnt work as good as fixing a sram p5 you take a 5 speed hub and make it a 3spd fixed

I had not seen those instructions before. Where does one get a fixing block for the T-3?

intenal hub fixed gear botch
 

i removed the high gear pawls from an AW and jammed up the low gear pawls with SW cresent pawls and 1/4 inch ball bearings in the groove where the pawls sit, pack it with grease to get the whole conglomeration to go in the hub shell and bobs your uncle! you have a 2 speed wide ratio fixed with a short lifespan!

this could have been a really cool idea in my opinion,
someone should make a 3 sp fixed hub w/ proper chainline and etc
