Here's a pic of my home made bar ends, not looking too shiny it has to be said- particularly the one that took the spill in the BP forecourt a while back. I've ordered a simple domed ended black pair from demon tweeks for a fiver with free delivery! At that price it's not worth me making a new set or re-skimming the old ones.
Treat everything in life the way a dog would- if you can't eat it or foc it, forget it.
