The Ryobi Tek4 (RP4530) Audio Plus Nose Suppression Headphones are full-coverage over-the-ear hearing protection headphones. Using the cutting tool, the pieces trimmed off cleanly and very quickly, and in a much safer manner than if I had been forced to cut the pieces off with a utility knife. For instance, the cutting tool was perfect for removing some extraneous plastic parts from a universal car stereo mounting kit I recently installed. The SoniCrafter is also useful for hundreds of other tasks around the house or shop. Attachments are easily changed or adjusted with the allen wrench, and many other tool accessories are available from Rockwell.
It certainly isn't a traditional woodworking power tool, but that doesn't preclude one from being useful around the woodshop. This one tool can handle a number of cutting, sanding and scraping tasks. While the SoniCrafter isn't a woodworking power tool in the classic sense, it does seem to be solidly built, and is great for cutoffs and other tasks that would be more time consuming if done by hand.The Rockwell SoniCrafter oscillating tool is Rockwell's entry into a line that was first popularized when Fein released their MultiMaster tool a few years ago. It works great as a variable speed oscillating detail sander, and includes a variety of sanding pads and discs. While it isn't a traditional "woodworking tool," it is very handy to have around the shop. The Rockwell SoniCrafter Oscillating Tool is a versatile power tool, as it can be used to cut, sand, scrape or polish not only wood, but also plastic, metal, brick, concrete and more. Most lumberyards will calculate it properly, but as you can see, just a small rounding can end up costing you quite a bit in the long run. It doesn't hurt to keep a small calculator in your pocket and calculate the prices to check their figures. When going to buy hardwoods, don't be afraid to challenge their measurements. This seemingly minor adjustment would end up costing you an additional $15.84 over the actual BF prices for the three boards. In other words, if you try to buy three boards of oak that measure out to 6.72 BF, 5.69 BF and 7.71 BF, the lumberyard might try to round each board up to 7, 6 and 8 respectively.
It's important to verify the price per board when you buy or sell lumber, because some yards like adjust to round numbers. In the second example, the price for that board would be $108 (6 BF x $18 = $108). For instance, if the two boards above were oak, and you know that the lumberyard charges $18 per board foot for oak, in the first example above, the cost for the board would be $90 (5 BF x $18 per BF = $90). If you know the board feet measurement of each board and you know how much the lumberyard charges per board foot, you can determine the cost for that board. In another example, a 6/4 board that is 8 inches wide and 6-feet long (72 inches) would be six board feet: (72 x 8 x 1.50)/144 = 6 For instance, a 10-inch wide, 3/4 board that measures 96-inches in length would come out to five board feet: (96 x 10 x. 75 inch in thickness4/4 = 1.00 inch5/4 = 1.25 inches6/4 = 1.50 inches7/4 = 1.75 inches8/4 = 2.00 inches and so on.The formula for calculating board feet is as follows:Īll of the dimensions in this formula are in inches. Typically, board thicknesses will be listed in fourths: 3/4 =. To begin, one must first understand the thicknesses of hardwoods.
A board foot is 12 inches by 12 inches by 1 inch, or one-twelfth of a cubic foot. Hardwoods are sold by the board foot, which is a calculation of the cubic size of the board. With hardwoods, the story is quite different. All of the boards of the same size in a stack at the lumberyard are going to be the same price. Softwoods are dimensional lumber, meaning that they are cut into uniform sizes (2x4, 1x8, etc.). While hardwoods and softwoods may look somewhat similar in size and shape in stacks at the lumberyard, the method for calculating the cost of each is quite different.
