Hi Ted,
It depends. You don't need a super precision lab quality machine to 
grade felt. A tire durometer, from a racing supply house, is a Shore A 
scale and cost about $60 USD. Since we don't order anything by durometer 
numbers, we're just taking comparative readings and that's a good enough 
tool for our purposes.
