Re: [CAD_CAM_EDM_DRO] Re: Test Peice for 3D finishing

Hi,

I was pulling an old laser printer to pieces the other day when an old
engineer friend turned up. I had just dismantled the laser assembly and in
it is an accurate hexagonal mirror. Seeing this his eyes lit up and he
started muttering about this being absolutely essential in a good workshop.
Since he tends to go a bit incomprehensible when he gets excited, I didn't
quite grasp the details of how you use such a thing, but he referred to it
as 'a polygon' and was muttering about 'collimating light beams' and such
like. Perhaps this could be a source of an accurate set-up tool - maybe used
with one of the 'pocket laser pointers'? Or is this all just rubbish??? ;o)
