Tom Steyer at JT Turning Tools has a new gadget for turners. As I understand it, although it has special application for hollowing, it can also be used to duplicate a spindle turned item. He has named it 'Cutter Vision' and apparently it will be debuted at SWAT.

More information can be found via a link on his website.

I have no financial interest in the company, although I own many of Tom's other offerings. I thought there might be some here who would find this interesting.
