Anyone know where I can get some small (compression) springs from (eg ~2mm diam

springs on ebay but they are too large.
Thanks
Wind your own either from piano wire (model shop) for stiffies,or from
guitar strings (very fine soft action springs, like ball point pens)

The technique is to get summat like a cordless drill in a vice, with
e.g. a 1.6/2mm drill mounted backwards, but a 90 degree bend in the wire
end and poke that down the chuck and maintain tension, set it going slowly..

If teh spring is to be used in compression, pre stretch it, If you want
dead flat ends use a dremel or bench grinder to set them.
