I think you mean capacitors, you should use 3, also I would recommend a schottky diode.
I haven't found the Schottky diode... but i have found 3 capacitors, maybe i can put one of these, in contact with two poles.
And, i have completed the mechanic part !! I have cut the two shaft and tonight i put the glue on the base of shaft !!
Spectacular.
