Instead, dimension your parts relative to one another, and adjust as necessary as you're cutting the parts. You will almost never be able to cut all your parts to final dimensions and have them fit perfectly in the end. Always start with a plan, but leave some extra material that you can trim away as-needed (not as-planned) during final dimensioning.Because most boards are not straight and flat when you buy them, you should buy slightly oversized (even if laminating) so you can mill them flat and trim them to their final dimensions.If you can find 3 perfectly flat 1x3s, your finished laminated board will have dimensions of 2.25in x 2.5in-just a hair under your 2.27in x 2.31in preferred size in terms of thickness. Yet another solution, especially if you have difficulty finding 3x3s or 4x4s, is to buy, you could buy thinner material such as 2x4s or 1x3s, and laminate (glue) them together. Length: 1.6m / 0.0254m/in = 62.99in / 12in/ft = 5.25ftĭepending on the lumber sizes available, you may need to buy either a 3x3 x 6ft or 4x4 x 8ft.Īnother solution is to adjust the dimensions of your finished parts to be slightly smaller so you don't have to resaw or waste so much material.Starting with desired final dimensions of 45mm x 46mm x 1.6m, let's convert to nominal customary units: If you need to go in the other direction, simply work backwards. Once you have the length in inches, multiply by 2.54 to get cm, then divide by 100 to get meters (or simply multiply by 0.0254 to convert directly from inches to meters). If the customary length is expressed in feet, multiply by 12 to get inches. Once you've converted the nominal customary dimensions to actual metric dimensions, you can convert the actual customary length to the actual metric length. Here are a few common equivalents: 2x4 = 38x89mm This is called a "soft conversion" according to the American Wood Council. To convert from customary units to metric, subtract 1/2in from the thickness and width, then multiply by 25.4 to get millimeters (1 inch = 2.54cm = 25.4mm), and round to the nearest mm. For example, a "2x4" is actually 1.5in x3.5in and a "1x3" is actually 0.75in x 3.5in. Typically a solid wood board sold in customary/imperial units is slightly smaller along its thickness and width, the thickness being the smallest dimension.
