I keep meaning to look around for timber/lumber places here to see if I can pick up some seconds or leftover pieces that are too small for them to use. Also need to check for some kitchen places that use Corian, see what they do with the sink cutouts etc.
I did find a skip bin place near me that allows people to go through their site and salvage any timber they would like. I havent gotten around to visiting there yet to see what sort of timber they have. Most of it comes from houses and building that have been demolished so im expecting it to be mostly pine, but may find others. Its free, so it couldnt hurt to take a look some time
