This likely isn't the only woodworker who has wondered whether a pinned or a pinless moisture meter is more accurate. - Editor
"I've had a Lignomat pin meter for a couple of years. I like it, but wanted something more convenient and noninvasive. Recently I purchased a Lignomat SDM. I also like it. Problem is, when I use the two meters on the same piece of lumber, the pinless meter always indicates about 2 percent higher moisture content than the pin meter. What gives? When looking for 7 percent MC, which meter should one rely on?" - Luther M.
The woodworker who asked this question did get some expert advice, both from "Wood Doctor" Gene Wengert himself, and from the manufacturer. - Editor
"When measuring the MC with the pinless, do you have 1-inch stock and an air space underneath? Did you use the actual density or a table value? Sometimes the table values are off. In most cases, the pin meter is most accurate, but how deep do you drive the pins? For the average of a piece, about 1/4 of the thickness. Sometimes the species calibration is off. Did you correct for temperature?" - Gene W.
"On the pinned model, I did use the temp correction table and the 1/4-inch pins (3/4-inch stock). The pinned model provides two species groups. For the pinless model, I used the density value from the Forest Service pub. The response from the manufacturer was that the pinned model would be more accurate. But ... for the cabinetmaker who wants to avoid holes in his finished product, the 'less accurate' might be less desirable. I'm beginning to think I need a calibration table for the pinless model." - Luther M.
What Tools Do I Need for Two Small Projects? from Woodworking.com
The woodworker who began this thread is a new woodworker. Like many, he has specific projects he's looking to complete -- and wonders what tools are required. - Editor
"Hi, I'm new to woodworking, trying to get started in it. I have two small projects I want to do and I want to know what tools I should start with to get them done. The two projects I want to do are to 1) Make a small wooden platform to raise up my TV a few inches; 2) I want to make a small wooden housing for my modem, router, microcel and phone. I'd want the back to be solid with holes for wires to go through where the shelf is." -Loucetios
You've heard it said before that there's more than one way to accomplish things in woodworking -- which, of course, means that the woodworker with the question received a couple of different suggestions. - Editor
"Do you have any tools available now? Providing you can cut square, you can use a hand saw, nails and glue. I prefer screws personally because they seem to be cleaner. I don't have a nail gun that shoots anything larger than brads and staples. In the end, all you need to do is cut and join the wood somehow. For the holes, I would use a hole saw or a flat wood drill bit. You'll need a power drill for both. A jigsaw could work, but I envision the hole to be less than 2" in diameter so that may be tight. Ideally, if you have access to a miter or table saw, you can ensure straight and square cuts. The same advice pretty much applies to the small TV platform." - SmileyFace
"For a simple platform, you will need a way to cut the pieces (hand saw, power saw, whatever) and a way to join them together. Could be nails, screws, dowels, dovetails, or a myriad of possibilities. Your choice. Could be done with nothing more than a hand saw and a hammer. For a phone shelf, again, many different joinery methods are possible. Nails would be weak here (unless you added a back), but screws, dowels, mortise-and-tenon joints, etc. would work. Tools required would include: a saw to cut the parts, a drill to make the holes, and whatever is needed to create whatever joinery you decide on (a drill for dowels, saw and chisel for M&T, screwdriver for screws...)" - Jerry M.
