QI recently purchased oak from a lumber mill that I plan to use for furniture. Some of the wood is more than 12" wide. Should this be ripped into narrower strips to glue up for panels in order to prevent cupping, or is it OK the way it is? Charles Jacobs Canton, Ohio A Rip it into narrower pieces, but only when individual boards show signs of cupping. If not, take advantage of the luxury of your wide wood. QDoes anyone have a handy way of determining what wood leftovers from projects to keep? I find it difficult to part with scraps: I seem to collect them for a year or so, then have a big throwaway party when I find I'm running out of shop space! And, of course, I always part with a piece I can use a week later! Someone else must have solved this problem. Tony Lazzaretti Andover, Massachusetts A I save the savoriest of hardwoods, like cherry and mesquite, for the barbecue. Solid wood strips of just the right width and thickness make nice stir sticks and glue spreaders. I like to build drawers and various sub-structures (webbings, glides, etc.) out of available solid scrap, like I can imagine they did in the olden days. Q When people talk about sanding, they usually start by saying "start A It's a matter of speed and efficiency. Each sanding step has a particular goal, and the idea is to reach that goal as quickly and efficiently as possible. The first sanding removes tool or machine marks, and 80-grit aluminum oxide paper does that quickly. Then, you must remove the 80-grit marks, and 120-grit does that. From there I go to 180, to remove the 120-grit marks. Finally, I sand by hand, going with the grain, using 180-grit garnet paper, which leaves a softer scratch pattern than aluminum oxide. I suppose you could remove tool marks with 220-grit paper, but my guess is that you'd use up about 16 times more paper, and time. It would feel a bit like digging a foxhole with a teaspoon. Michael Dresdner I usually take it a scrap at a time; if it looks compelling, I'll keep it around. I also have a friend or two and other associates who hit the scrap bin on occasion for various art, cabinetry or heating applications. I also find myself diving in there almost daily, looking for some little piece of something. I tend to let some better stuff go into the scrap bin, knowing that it'll get used eventually, for something other than kindling. I try to save all I can, out of respect for everything.
