I talked to a friend of mine, Noah, and he had an old 60 gallon air compressor that had burnt the drive motor. We made the connection yesterday and I picked it up. He had informed me that it had also stopped compressing air. It's not a good sign, but I got it back to the shop yesterday and pulled the compressor apart and discovered that the reed block is worn pretty good. It appears that one reed and seat is worn substantially, possibly a defect in manufacturing. I got it all back together and put a drill on it to turn and it sounds like it could be compressing again. I'll be going out this morn to find a motor mount for an old motor I had in the shop to temporarily mount on the compressor.
