Horn Repair
I bought a Stewart Wagner horn and it worked good until I took it apart to clean and paint. I forgot the nut on the ratchet wheel was left hand so I tightened it until it broke instead of loosening it. Now I have an armature shaft with no threads on the lower end. Does anybody know somebody who can weld (or silver solder) a new left hand 10-32 stud back onto the shaft?

Re: Horn Repair
Center up the armature in 4 jaw chuck in a lathe, bore and tap for right handed 10-32 screw. Install and tighten screw, cut off screw head at required length. All other horns are right hand tread. Use loctite on thread if you like.

Re: Horn Repair
Just found out it needs an 8-32, not a 10-32. I'll try the lathe bore and tap if I can find a friend with a lathe.

Re: Horn Repair
"Sometimes" if you have threads showing, you can study them & determine if they're R/H or L/H threads.
