In this thread: http://www.penturners.org/forum/f14/plastic-106499/
the question was asked, how are the numerous types of plastic blanks different from each other. I gave a short (possibly terse) answer and I was surprised how much interest the thread got.
Our new librarian (and one of my good friends), Wayne suggested that we try to get answers that were "library-worthy" and incorporate this as an article. Honestly, I think that is such a good idea that I am starting a few of these threads and I will incorporate the information into an article for Exotics and make it available to the IAP Library.
So, lets start with this thread:
How would you describe turning Acrylic Acetate?
To me, it is the easiest of the "plastics" to turn, it is fairly dense and predictable to turn. It has a noticable smell, which some describe as an "odor", I don't find it offensive.
AA can be turned to size and sanded up to 1000-1500 and then Novus 3 and 2 can be used to polish. OR, it can be sanded with MicroMesh to 12000 and it will shine. OR, it can be buffed after the 1000 grit with Tripoli then white diamond---a third wheel can be added with jeweler's polish.
To me this covers "Acrylic Acetate" and "Acrylic"--anyone differ?
What are YOUR thoughts?
