What is the best equipment to use to edge 18 mm small "b" measurement frames and what is the best choice in equipment to edge high wrap frames and lenses ? Is the high wrap problem confined to the tracer and not the edger ? Is the small "b" edging problem primarily a edger constraint or is it also a tracer constraint ?
I assume that when it comes to modifying shapes by changing the "b" measurement then this is strictly a matter of whether the tracer can edit the shape ?
Are there upgrades to a Nidel 7070 LE built in tracer that would allow it to edit shapes ?
