disassembling freewheel bearings
I searched around and found that the general concensus is to pitch a freewheel rather than trying to service it, but I have a slightly different situation.
I need a singlespeed freewheel with about 30 or 32 teeth, which simply can't be had commercially. My plan is to weld a 32 tooth sprocket from a disassembled multispeed freewheel onto the outer housing of a common BMX singlespeed freewheel, but I need to undo the bearings to have any hope of welding on it without damaging things too badly.
I see that most (all?) freewheels have a plate or nut that accepts a pin spanner. Are these a standard size, or does this vary?
Which way should this be turned to remove it? (advance warning of lefty threads is always nice...)
What will I find when this part is removed? Is it a bearing cone, or is the bearing actually contained beneath this part?
Anything special about putting it together? Lashing the bearings, etc?
This is for a retro-direct conversion I've been sitting on for too long now. Time to scare up some parts, break out the welder, and get a rideable product.
