Probably not the right section to post in, but the one I thought I'd have most chance getting advice!
 
	 
 
	Has anyone had metal knobs turned, and if so, could you put me in touch with the person/company that can do this please? Actually looking for a clutch for a telescopic lamp, but is the most difficult thing I've ever Googled! Thought a turned bass knob would be much the same technique. 
 
	 
 
	Thanks,
