Patso, That is good advice from Thurman. I had a similar problem recently, not with a tool, but with getting a problem fixed on a 50 year old furnace blower motor. A friend told me of a really old time electric motor repair place 25 miles away in Hollywood.
They did not have a Web Site so I just took my motor in and was amazed that in their Store was a whole world of old time skill, knowledge, and parts. The whole place looked like a 1940 repair shop movie set. They knew all about my problem and fixed it quickly and very reasonably.
