I am currently using up piles of scraps from previous jobs. the most scraps accumulated when we did an alteration (complete rebuild) to our bathroom. THE BOSS did not want me to do the job as she was afraid it would drag out too long since i was just getting started with my landscaping for the season. I had to agree since it is the landscaping that pays the toll.
I did build a stairway down into the cellar, as the stairwell had to be rebuilt as part of the project. When the builder saw that the stairs fit perfectly when they were installed, she decided to let me do milling of the rough lumber that i had for doing the panelling and trim work. She had two carpenters and other trades men working and I had to go full speed and nites to keep ahead. Any scraps/off cuts were just tossed to far end of shop. that was two years ago. Last winter i started piling the remains and salvaged some of it forprojects. this winter i am still doing the same, but i can now move around the shop without banging my head on the ceiling joists :
I also have several pieces of firewood that i have cut into blocks on the bandsaw. Some short tree limbs cleaned up from customers yards have also been sawed into blocks. The blocks of wood are anywhere from 12" to 24". Thickness about 6"x 11-12" width (limited by thickness planer capacity)
I tried milling several logs from trees i had removed from customer's properties. i decided that was, for me, a waste of time and potential for extreme back problems. Too much time lost with stickering and not enough level area to do the stickering anyhow. I found it was much more fun to go to the mill and purchase rough cut lumber already air dried. I only had to load and haul the material one way. I still have a pile of red oak in the barn that is also part of the reason i no longer have my own logs milled. They did such a terrible job that i think it costs me more to thickness plane the boards than i ever saved by doing it that way. There are other mills around, but,as i said, it is much easier the just haul one way.
When I was in construction, i used to save pallets. It was a real hastle to remove nails and there were always a few that broke off. That turned out to be an expensive waste of valuable time. I still watch for decent pallets and bring one or two home. I try for a very short few minutes to get nails out. They are too resistant to nail pulling tools, I just attack what i can with the chain saw and haul the rest to the dump. I don't like to run the nail ridden pieces thru the woodstove as that presents other very unfavorable problems.
So, after all of that, the direct answer to the question is: Yes. i am a scavenger when it seems to make sense to be one. Of course, my idea of what makes sense does not always meet with the approval of [censored] I am sure i need not explain where the dis approval originates.

PS I have managed to acquire several great pieces of spalted wood from various yard cleanups. Those can be terrific surprises now and then.
