When you say "it did not go well" .... please elaborate .
Is it chipping ? ... or what ? . Turning this material is quite different from turning the usual "acrylic acetate" for example
One of the blanks you show (on top of the pile) shows some moderate chipping ... that is not out of the ordinary for "inlace acrylester" .
I would say that you have done well up to that point.
Now that you have it partially rounded, the turning should go better.
BUT ... you do have to use sharp tools and you must take very light cuts. . Carbide tools are better than HSS only because of less sharpening.
Some people use negative rake carbide cutters, and some of those say that the negative rake makes a difference while others say it doesn't.
