FYI,
ESKO does sell replacement parts for some of their tools. The kicker is that they don't have anyone in house anymore who can fix them. So if you can find a machine shop to do the work then it will save you money, rather than buying the whole tool. The replacement part for the tool I needed was $65 bucks. Its held in the tool using 648 Loctite and it will take 250 degrees to loosen the part it self to be replaced. Also the guy at Esko provided me with a diagram that shows how the tool should be assembled.
