Hi,

Marina Square mall and i12 Katong mall both have music instrument shops. Should be pretty easy to find.

Hi Eric

Thanks for the tips.  Never thought of taking the DIY to the next level - shame on me! 

Now I need to find a local source of piano wire (in 9V/9M) 

Thanks again Mike

They aren't difficult to wind. K&S Metals has small dia. piano wire. Use an ordinary screw as a form. I usually go with a screw the next size down from what I want as they tend to unwind a little. You can also wind them on dowels and bamboo skewers. I do this often when I need one right away for development, then replace it later when I have time as the commercial ones have much nicer finish winds on the ends.

Thanks for the suggestion Niels. That was one source of springs I hadn't thought of. Those that I've checked so far are either wrong ID for the 3mm screw or wound in wrong "sense" .

Continuing to look. Closest I've found is tensioning wire for net curtains but all I can get here are too small ID
