I have eyed up the sealing film on yogurt cartons as a likely material for
making replacement valves, but was discouraged from this idea in a workshop
session where Rick Epping informed us that a windsaver is not just a simple
flap of plastic, but that it has two components: the spring and the sealing
membrane.
In vintgage accordeons there was apparently an actual metal 'hairpin' spring
which closed a leather flap.

Yes, I was talking about them 2 weeks ago. I forget the French name for them. I used to use them on accordeons. You can do the same thing but you will need something a little weaker. I suggested a cat whisker OR a paint brush bristle. (btw, it needs to be tapered)


Nowadays I understand that harmonica valve material may in fact comprise a
lamination with the "spring" material on top and the sealing element
underneath. Consequently it might be possible to inadvertently mount a valve
upside down and get less than terrific results.

The don't work well upside down lolol smo-joe
