I am refurbishing a small hydraulic jack which, apart from not holding
it's fluid, is in excellent condition. Over the course of the past
seventy odd years the two leather washers 'which do the business' have
become very brittle and need replacement.
They are cup washers as per bicycle pump. The ram washer is 1" dia.
cupped to 1/4" deep , made from 1/8" thick leather. The pump washer is
1/2" diameter otherwise the same.
What is the best way to produce these I wonder? Or, by any good chance
are such items still available commercially?
Any pointers gratefully received.
