Sudden thought, are you compressing the nylon end-to-end, or sideways ?
For some reason I assumed it was e2e, but splitting the nut down one side and cramping it inside an outer sleeve would be easier.
An alternative would be to split it into two halves, keep one fixed and move the other sideways, possibly with an eccentric adjustment. Possible ?
