I conducted a Google search for an obsolete service repair part and found Kauffman. Kauffman Family Tool Repair was very helpful even to the point of giving helpful suggestions on ordering the proper items

Fantastic little shop that had exactly what I was looking for. Pretty impressive considering how obscure these particular parts were. Reasonable prices, fast shipping, and wonderful customer service. Little touches like personal follow-ups and candy in the box go a long way. Thanks for doing what you do!

Parts got here, and installed. I have not yet tried it, but I see no reason why the sander won't work. I am just impressed that you folks have the parts. I checked about a dozen internet sales companies, and you were the only ones to have the parts.
