Re: Test Peice for 3D finishing

Ian,

Thought for a minute you were talking about me! But yes, I'm curious
what we can use the laser and mirror for. Let's make it do edge
finding! I haven't a clue how. X-ray treatment (linear accelerators)
machines use lasers (and probably those little mirrors) to delineate the
treatment field on the patient. Shine the laser light down the "bore
site" and onto the scribed and/or punched marks on a part?

Just thinking out loud.

PS, I notice some messages still get ad's?
