Thank you for referencing the source. It is very gratifying to see that people from all over the world have an interest in this. I'm sure the metric version will get a lot of use! I like your personal spin on it with knurled nuts. Very elegant. Is that stainless or aluminum?
As Werowance noted above these work great with ball oilers.
