Vibratory bowl finishing - ebonite and acrylics/resins

[NewtonPens]

Okay - so.
I got my 3 test pieces back from Kramer. They didn't say what they used in the note, but the results are pretty good.
The regular acrylic was very shiny. I'd be happy to send it to a customer.
The ebonite was about 90% of the way there. Maybe more time in the bowl would get it there.
And the alumilite... ugh. Maybe it would be fine with double the time? Dunno. It looks only very lightly buffed up, especially compared to the other two materials.

With an 8 hour run the acrylic is perfect, the ebonite is nearly there, and the alumilite is still matte.
