Teac A-3340 Capstan shaft 6mm and many others

Standard shaft for most TEAC  1/4 inch machines not just the 3340,

Before I was cleaning these up but there has been a huge discussion about the best way to do this, some people want to send it out to a shop to be done others like me put a bit of 3-400 grit wet and dry paper around an old pinch wheel and let it run.

So for now I have left them as they are with dirt or debris or more commonly glassed up

The Half inch machines use a tiny bit longer shaft

For reference please these are 75mm long by 6mm
