a number of questions regarding plastic/nylon/delrin-like materials...
i have a couple scrap pieces of a product called 'weatherguard' (? i can't find much of anything like it googling), as well as more pieces of a product called 'Starboard', and lastly a number of more scraps of a product called 'Azek'.
Azek is an exterior grade pvc material that will do for certain pieces of a homebrew cnc, but i have no idea how it will take to tapping... (seeing as how i am tapped out of taps; i'm still unsure what sizes i need)...
following is a quote from a site about 'starboard', not sure how it will take threads, either; it certainly has a denser, slippier feel to it than the Azek:

the 'weatherguard' felt even denser and almost greasy, compared to the azek and starboard...
does any one have experience machining these materials, and do they take to tapping readily ? would the 'dense', 'greasy' polymer stuff substitute for delrin ?
thanks
