At my wit's end here. Got the bearing and rod inside finally, only the rod is crooked and now the bearing is damaged. It doesn't spin. I cannot straighten it. I cannot remove it. I maybe could remove the rod but for some reason even that is proving difficult whereas it never was before. I think it's because it's making contact with the inside of the saber's neck. The bearing is all the way up in there, and it was difficult enough to get in, I don't see any way of getting it out now. I've tried using a dowel, and then a screwdriver, and with a hammer using it to push one side of the bearing in an attempt to straighten it out, but it's not working. Also probably how I damaged it.
The rod is at the correct length for the emitter, so at this point I'd settle for just being able to straighten it somehow. Also inclined to pay someone to fix it for me at this point, it's making me crazy.
