Looking For Someone That Machines Knobs

There's a local machine shop a few miles from where I live that could probably do what you want. Email me@your convenience.

Thingamaknobs. Designer is a man named Scott and his work is fabulous . He uses many exotic woods and the quality is first rate .

Yes Blue Circle does or did sell wooden knobs from various kinds of wood.
Their stainless steel knob was more expensive than the wooden ones.
I am sure if you email Gilbert at Blue Circle he certainly could give you a few tips.

I have picked up wooden knobs ,from Audiogon, in the past.
