Waterpipe, it has the right diameter? ohh, did'nt think so. otherwise you would have bought it already.
Upsets me? no, just get irritated of people how know how much things should cost when they apperantly have no clue what it takes to make the part. But hey, here is a tip, buy a lathe and a big pile of copper or brass then make this things and sell them for 50 cents, if you are right about pricing you will be a millionaire.
Agree, some people.....
Ps, i own a lathe and basicly a machineshop (not in the business, privatly) and often, really often, practically everyday, meet this type of people.
