Hi!
This is for those of you who have some kind of chain oiler - then it works marvellous.. It's a standard nail brush, cutted to size and screwed in place. While chain goes through, it gets scrubbed. For first few miels there is some drag on chain, but it gets much better. Obvoiusly it wears out after a time, but since cost of this is so low....
Enjoy!
