It won't happen again sir...
Because the brushes started sparking as it ran and I got scared so I hit with a hammer and threw it out. Shame really as I wanted to use it in as a forge blower.
I have spent about half the day clearing up the mess it made though.
Fix isn't the word I'd use, though it make it much quieter and it did stop the arcing.Using a hammer to fix an electrical problem ! Ten out of ten, disregard my first post in this thread !
