There is at least two threads on here referring to using tubing as the drive belt for treadle machines.
My wife bought us some to try because every time I go to use one of my treadles the darn belt has stretched and the machine slips.
So, my question is this. How much short do you make the tubing to give it some tightness?
I don't know how much it will stretch so I'm asking first.
I've PM'd vintagemotif because I know she's done this, but if anyone else has done this I'd like to hear from them too.
