[sdiy] Cutting rotary encoder shafts??

[Theo]

There is a fourth kind, the small "circular saw" blade.
Its very suitable to cut though plastic shafts.

But I prefer to use a electrical "hack saw??" to cut shafts.
Have a piece of wood of equal thickness as the intended shaft size.
Drill a hole though it where you can stick the shaft though.
And cut it using the wood surface as a guide for the saw.
Used this to cut over 700 alps potis to size.
The nice things about this method are.
- there is no stress on the pot, the shaft is supported.
- all shafts get equal size.
- works fast, did about half of those 700 in one hour (cutting 6 at the same
time).

Cheers,
Theo
