I have a Kemble 6 octave, 85 key small piano - from the 60s! Its a lovely thing, bright sound. The only problem is..
The sustain pedal did not work when pushed down. It lifted the hammers off the strings slightly, but not enough to make any sort of sustain sound. I tightened everything under the pedals etc, no effect.
So... I stuck a pen lid on the end of the rod to lift the lever higher, so now, when fully pressed, there is a good sustain. The problem now is: the pedal is amazingly stiff and unresponsive as it is always pushing the lever up a bit. To push it down fully is too hard to be playable.
The lever the rod goes to was topped with a rubber tip, which had eroded, so before the rod would scrape off the lever. There was no hole in the lever for any kind of rod with pin in it.
My quesiton is - do I try to replace the rod tip? do I try to replace the rod and or the lever?
LASTLY: CAN THIS ALL BE FIXED BY A TECHNICIAN TWEAKING SOMETHING ELSE? IS THERE ANY OTHER WAY TO FIX THE SUSTAIN BY TWEAKING?
