Delrin was (Re: all-thread question

Hi Russ,

Let me know the size piece you need for the Delrin.

I have some of what I think is black Delrin plate, 1" and a 2" rod
too.

If you wanted to buy that stuff, McMaster Carr again. A 2" bar, 12"
long goes for about $13.00.

My question is how to tell if the stuff is black nylon, or black
Delrin. Is there a simple test ? (fire, file, folding?)
