Current Projects chat and miscellany

hugo7 - check the links above they should explain it pretty much,. basically all the excess space in freehub is filled with a metal epoxy jamming and sticking it up tight (be patient before riding - it takes a day or so to harden )

s3x cogs are just cogs for the s3x hub - single speed cogs that fit a shimano spline - see

''Single Cassette Sprockets and Spacers''

at http://www.sheldonbrown.com/harris/singlespeed.html#s3xcog

nothing more special than single speed cogs for shimano free hubs really

even the cogs off a cassette will work (but i didn't have the right sizes here )- single speed cogs are better as designed to keep chain on more. spacers and 12t cog came from a single speed kit - plus 2 more cogs in there too .

After reading this thread on the mtbr forum I separated a shimano hyperglide 7-speed freewheel block so I could convert it into a SS freewheel (see pic below) but in practice, as you mention number6, the teeth were not deep enough to stop the chain being thrown off when ridden. The mtbr forum thread suggests using a cog from a shimano uniglide block as they have taller teeth and are therefore better suited for this application. It was an interesting little project though and in the process I made contact with this parts supplier (Loose Screws)in the US who said they had a 15T uniglide cog they could supply me with but in the end I bit the bullet and bought a new rear wheel with a freehub and a SS kit and did it that way.
