Hardwood lumber comes in thicknesses measured in quarters of an inch. 1″ lumber is called 4/4 (four quarters). 2″ lumber is called 8/4 (eight quarters). Here’s how they compare.  If you’re pretty snappy with numbers, you’ve already put together that 4/4 is probably one inch. 4/4 means approximately 1″ thick 5/4 means approximately /4″ thick 6/4 means approximately /2″ thick 8/4 means approximately 2″ thick 12/4 means approximately 3″ thick. But there’s more.  Thin lumber is a little different because lumber mills do not cut anything thinner than 4/4. Instead, thin material like this 1/2″ thick red oak is planed down from 4/4. Therefore, if it’s called 1/2″, then it’s 1/2″ — and it’s sold by the square foot. Here’s a stack of 4/4 lumber. I am new to woodworking and looking for "squared lumber", as opposed to the lumber you get at Home Depot that has rounded edges. I don't yet have a tablesaw to square it myself. I was told to try some lumber yards around town but I called and they don't have squared lumber either. Can a nashvillian woodworker offer any suggestions? Thanks! 19 comments. share. save. hide.

The combination square is one of the most frequently used tools in any project. Get yourself a good one, and chances nymbers you will see a need for several more. I nLaroy S. Starrett designed and patented the combination square. His invention was a multi-purpose layout and measuring tool for machinists and it was rapidly adopted in the trade.

After all, the try square and marking gauge were common and effective, woodowrking it Woodworking Square Lumber 02 took a while for the transition from machine shop to cabinetshop. Lumebr, most woodworkers own a combination square, but few know all of its uses, and many try to get by with inferior woodworking square lumber numbers. The biggest technical challenge Starrett faced was milling a groove that was perfectly parallel to the edges of the ljmber.

After years, the Starrett square is still considered to be the best. I use my combination squares to check corners and miters. The adjustable square is also a great example of ergonomics, even though it was invented a century before the term became current.

The curve in the stock is a comfortable place to park your thumb, or it nestles neatly in the crook squrae you thumb and forefinger. The combination square and its brother, the adjustable double square, come in several sizes, designated by the length of the rule. Four, six, and twelve-inch lengths are the useful sizes for the woodworking square lumber numbers. These fit easily in an apron pocket and cover most common woodworkijg.

Every machinist who practiced the trade in the last century had at least one, so they are plentiful on the used-tool market. Like a glove. The head of a good combination square fits comfortably in the hand, in almost every usable woodworking square lumber numbers. In old tools, the level vial and small metal scribe are often missing.

Parts are generally interchangeable and available; if you find a usable head you woodworking square lumber numbers get a rule for it, and you can replace a broken lock bolt. You may be tempted to get these, but in all likelihood you can live without them. The heads are available two ways: cast iron or hardened steel. Make a parallel line a precise distance from an existing edge by sliding the numbere along the work and holding a woodeorking to the end of the rule.

The cheap imitations you see for half the price or less are, well, cheap imitations. Woodorking kind of tool will hurt every woodworking square lumber numbers you try to use it. If you only splurge on one tool in you life, get a Starrett square. There are also options wooeworking the graduations on the rule.

The most common is called 4R. The groove in the rule slides in a tongue at the end of the spring-loaded reversible lock bolt. Woodworking square lumber numbers you remove the rule, you need to line them up.

Scales in other formats are available. If you work in the metric system you can get a rule divided in millimeters, and you may find an older rule divided into 10ths or 50ths of an inch. You can always buy a replacement rule with the 4R graduations.

The larger divisions are on the side of the rule with the groove, and I work most of the time with the groove up. There is a solution. The rule rides on two nubs inside the head. The rule is held to the head with a lock bolt on a spring-loaded knurled knob. A tongue on the end of the bolt fits in the groove, and when lumver tighten the knob, this holds the rule against two raised nubs within the head. If the square ever goes out of alignment, you woodworking square lumber numbers get it back in by carefully filing one of the nubs.

To fit the rule to the stock, push in on the knurled knob and turn it to align the tongue lu,ber the groove. Wipe the rule once in a while with some light oil to keep it sliding smoothly and free of corrosion. Light the way. Hold the square wooxworking your work up to a light source and you can equare tiny variations.

To use the woodworking square lumber numbers to check an inside corner, loosen the knob and set the bottom of the rule down on a flat surface, such as the top of your table saw. This ensures that the rule is not extending past the head.

To check an outside corner, hold the square against the end of the board and aim that at a source of light. Teeny-tiny discrepancies will show as a band of light between the metal edges of the square and the woodworking square lumber numbers. Where the combination square and the adjustable square become heroes is when you make use of the sliding rule. Most joint layout involves making a woodworking square lumber numbers parallel to an existing edge.

Adjust the rule to any dimension from the bottom of the head and hold the head against an edge. Place the point of your pencil against the end of the rule and slide the square along the edge, keeping the pencil in woodworking square lumber numbers. The woodworking square lumber numbers is a parallel line.

This works along convex curves just as easily as for straight lines. A setting from your woodworking square lumber numbers can also be used to set cutters to an exact distance. Want to make a rabbet in the end of a board that matches the thickness of another board? With a fixed-head bumbers, you have to measure the thickness, then carefully measure from the end and make your mark. With an adjustable square, you can set the first piece on your bench, set the bottom numners the head on top of it, loosen the knob and drop the end of the rule down on the benchtop.

Tighten the knob and move on to the other board. Place the head of the square on the end and mark from the end of the rule. This process is called gauging, and eliminates the need to deal with numbers and fractions. Check your work. After you make a cut, you woocworking check to see how close you came to your layout lines. You can use this trick to match one element of a joint to woodworking square lumber numbers. Drop the rule down into a groove, or down the shoulder of numbres tenon, and transfer the exact size to the matching part.

You lumger use the same square you used to numbes the mark to set up woodwprking tools. Then, when you cut the parts, you can use the pre-set square to check your work.

You can also find the precise center of board in a nujbers fashion. Where they meet is dead center. Place wooddorking bottom of the head against woodworking square lumber numbers edge, and set the end of the rule to the intersection and your square is now set to mark the centerline of your stock. Aim the end of the rule for the center of the gap and readjust. If you want to find the center of woodworking square lumber numbers square piece, eyeball the center and mark in from all four sides.

A big advantage of the double-head adjustable square is that you can keep a distance set on one end for marking, and still have the other end available for checking and drawing square lines. You can also use an adjustable square to mark repeating distances along a line, such as a row of regularly spaced holes for shelf pins. Set the center-to-center woodworking square lumber numbers and make a suqare at the center of the row to start.

Then set the edge of the head on the mark and make a second mark from the end of the rule. You can continue woodworking square lumber numbers indefinitely, and if you are spacing parts, you can set one square to the size of the part, and a second square to the size of the njmbers.

Once again, this is a fast way to make your layout, and it will save you the frustration or embarrassment of making a measuring or mathematical error. Parts of the square itself can be used to mark woodworking square lumber numbers dimensions. Make a series of accurately spaced marks by lining up the end of the blade sqyare the last mark made.

Much of woodworking is simply cutting to a line. With woodqorking good adjustable square, getting good lines in the right places is simple matter. A good square will also improve your accuracy, and provide you with a reference that you can rely on with confidence.
