Once I get my next batch of 30mm optics from Elektro Lumens, I'd like to get them to desired diameter by turning instead of belt sanding, which always seems to result in scratches and a barely circular, rough circumference.
I can only think of two ways to "chuck" the optics:
<ul type="square"> [*]1) chucking the very edge of the optics and using a live tailstock center inserted in the emitter hole at the bottom or
[*]2) boring out a 1.5" rod to a conical depression, filling it with "Blue Tack". and sticking the optics into it, being careful to keep it centered. [/list]
With 1), you can't turn the chucked edge. 2) will probably work if the cuts are kept light enough not force the optics off-center.
Any other ideas?
