There's a company in my town that produces laminate top furniture, mostly the electronic industry; they throw away all kinds of laminate tops, shelving, and laminate all the time. (Their dumpsters are like treasures chests!)
I walked in one day, and asked them for some scrapped laminate, after sharing with them a little about myself, and they gave me a full sheet! The laminate top is great for making templates(patterns), and also a "cover piece" for my scroll saw over the hole(where the blade goes thru), for cutting real small pieces. I just use double stick tape to adhere to the top. The material is very hard(and brittle), but also quite thin(maybe 1/32"). I also have gathered broken chairs, the kind that have the spindles(like kitchen chairs), I cut the spindles up, and use them for handles for hand-made tools+ the seat, I use for stock. They are generally made from oak. Also, we have a lot of old factory mill buildings around(Lowell is the "mill city"), where I have obtained oak slats measuring approx. 2"x 1/4" x 2' . They're perfect for making name chains/zipper pulls, etc. They came from some 100 year old production carts, with these 5 lb. cast iron wheels! Really cool, if you like old things. Also, I have gotten stacks of wood, mostly hardwood plywood strips(many sizes), and even some 1/2" maple boards(2'x2'), that were slightly marred, or stained, that they couldn't use! Furniture companies are an excellent resource for all kinds of cut-offs and throw aways; their stock has to perfect for production needs, so...there I am! I have always developed relationships with neighboring sawmills, furniture factories, and electronics companies, etc. and showed them what I do; the resources are all around us, it just requires a little snooping or detective work, as well as some personality! People are usually very accommodating...
