I was answering a neighbor's question today, and went back and looked up
Delrin and UHMW on the web, and found that I did not know what I thought
I knew. ;-) Apparently Delrin can be sanded and polished, while UHMW
is not good for sanding, according to what I found on a couple of websites.

So which plastics are good for sanding and filing? Is Delrin a good
choice? I am talking basically hand work, or perhaps using a belt
sander. I want something that can take a smooth finish, preferably is
food and dishwasher safe.

Thanks in advance.
