Hi rokkon,
good to hear that the alcohol/spirit cure worked! As said, it takes some time and work to get
it properly done - I had not the patience in the first run so I had to make it twice, disassembling
the wheel makes it easier to clean everything but it's timerobbing.
I am working actually on a real wheel and a button box which will be running via Arduino.
Still some steps to go but looks promising.
When I've completed this, my old, original wheel is vacant, so if you need the black plastic body
which contains the shifters and the wheel I could send them to you.
Otherwise if you are interested in building your own wheel, have a look on thingiverse
or other 3d printer file platforms, I printed my button box at a friend and so far it looks and feels good.
But be aware that, if you build your own wheel, you have to extract the pcb from your wheel and put it
in an extra/separate housing as you need the original electronics for setting up/calibrating the wheel
at startup.
Despite direct drive wheels are out some time, the CSR Elite with Bühler mod is still a very good wheel
in terms of force and accuracy - it's worth to play with it.
When my real wheel is ready I will post it here but here already a little spoiler and a picture of the plastic
housing you need:
