[sdiy] Slide pot cleaning

[chris]

When I opened some slider pots for cleaning a couple of years ago, I 
didn't bend the lugs back - I soldered a stiff wire across the bottom of 
the case, in order to close it. That way the lugs won't break from 
fatigue if the procedure needs to be repeated some day.
