What are your strange but essential finishing lab tools?
For me it is this thing
A drywall sanding sponge. Soak it with water and it is an amazing tool for smoothing rolled lens edges, dulling edge polish, and any number of other uses. I love this thing, just used it to finish up a -17.50 zeiss 1.74 individual lens that I gave a roll to and it smoothed it perfectly.
All for $5.27 at the hardware store!
What are your strange but necessary things in your finishing and/or surfacing labs? I remember some of you have a few interesting ways to get rid of swarf on poly lenses.
