Measuring Tips and Techniques for DIYers
Use these clever tricks to work faster and better
One-Inch Stop Block for Multiple Cutoffs
To get furniture-grade crosscuts, you must use a table saw. When Senior Editor Travis Larson crosscuts a whole pile of short pieces to the same length, he clamps a specially dedicated block of wood to the table saw fence. It’s an old standard trick, but the difference is that his block is laminated for easy sliding. More important, it’s exactly one inch thick.
He clamps the block on the fence and adjusts the table saw fence gauge to the desired length, plus one inch, and saws the pieces. The one-inch thickness eliminates any head-scratching and mistakes from using any old scrap block. For safety, he positions the block so the work piece he’s cutting loses contact with the block before the cut begins. That all but eliminates any chance of kickback.
Add Fractions Fast
Adding 1-13/16-in. to 3-3/8-in. (or any other fractions) doesn’t have to hurt. Just line up two rulers or tape measures side by side and read the answer instantly, with complete accuracy. It works for subtraction, too — just read the numbers in the other direction.
Circle Gets the Square
Copy Center Project Patterns
Enlarging scaled-down woodworking patterns to full scale is a lot of work, and the results are rarely accurate. But you don’t have to go through that exercise anymore. Just about any full-service copy center will do it for you in a couple of minutes for a couple of dollars.
Cut the pattern to the actual length of the drawing — our magazine pattern measured 3-13/16-in. Ask to have it enlarged to the size called for in the dimensions. The copy center magician will spin a circular gauge to determine the expansion percentage and punch that info into the copier. In less than a minute, the full-size pattern will roll out.
Our 35-3/4-in. Adirondack leg pattern cost less than $2. Stick the pattern directly to the wood with spray adhesive, double-faced tape or masking tape and cut out the part. That’s it!
Dead-Center Drawer Handles
Here’s a quick and easy way to perfectly center drawer handles and pulls and mark them for drilling. Use a straightedge and light pencil lines to mark diagonals from the corners of the drawer face to pinpoint the center. That’s all you’ll need for a single screw handle.
For handles with two holes, adjust a try square to the center point and scribe the horizontal handle line. Divide the handle hole spacing (usually three or four inches) by two and mark the drill holes on the line on either side of the center. While you are upgrading drawers, here are 18 kitchen upgrades that will make your home look expensive.
Improved Marking Gauge
Marking gauges come with a little metal pin that scratches a line on the wood, but it’s hard to see the fine line when you’re working. So Family Handyman editor Ken Collier drilled out the pinhole and stuck in a pencil. Now it works great for tracing cutting lines on rough boards and laying out screw hole positions along cabinet edges.
Mark, Don’t Measure
Holding trim in place and marking it is always more accurate than measuring, often faster and eliminates mistakes. This is good advice for other types of carpentry work too, like siding, laying shingles and sometimes even framing.
Here’s a nifty way to trace cutting or drilling lines on work pieces: First drill a 1/8-in. pencil hole one inch in from the ruler end of a combination square and adjust the square to the desired dimension. Then stick in the pencil and pull the square along the board edge to trace the line. Be careful to drill a hole that’s only a smidgen larger than the pencil point. You’ll be able to speedily produce straight, crisp lines for all kinds of jobs. Here are more cutting tips.
Memory (or Lack Thereof) Trick
Stick masking tape to your tape measure for jotting down shapes and numbers. That way you won’t forget the length on the way to the saw. Feng shui is still a thing!
Perfect Keyhole Template
When you’re installing a wall hanging that has keyhole slots on the back, create a template to help you position the wall screws. Lay a piece of paper over the slots and do a pencil rubbing a la Sherlock Holmes. Level and tape the guide to the wall. Mark the top of the keyholes with a nail and your screws will be in perfect position.
Slant-Ruler Board Divider
Want to divide a board or sheet of plywood perfectly in half, into thirds or any other equal fractions? Here’s a great old tip that’s worth revisiting. To halve the board, line up the end of a ruler or tape measure on one side. Slant the tape to read 8-in. on the right edge and make your mark at 4-in. To divide it into thirds, slant the ruler to read 9-in. and mark the board at 3-in. and 6-in.
The key is to select a measurement that’s easily divisible by the number of spaces you want. For example, if you want to cut a sheet of plywood into six sections, use the 60-in. mark on your tape measure. Measure at a 90 degree angle from one side to each mark to get the real numbers to transfer them wherever you need them.
Testing Table Saw Miter Cuts
An easy way to test whether your table saw is set to 45 degrees is to cut off a short length of your trim, then hold it to a square. A gap means your angle is off. Here’s some table saw tips and tricks.
Set the Blade Depth Before Cutting
Determine the blade depth by unplugging the saw and holding it alongside your board with the blade guard retracted. Then loosen the depth-adjusting lever or knob and pivot the saw’s base until the blade extends about 1/4-in. to 1/2-in. below the board. Tighten the lever or knob and you’re ready to saw.
Easy Framing Formula
You don’t need a math degree to estimate framing materials for walls. Here’s a formula that works every time, no matter how many doors, windows or corners your walls have:
- One stud per linear foot of wall;
- Five linear feet of plate material (bottoms, tops and ties) per linear foot of wall.
It will look like too much lumber when it arrives, but you’ll need the extra stuff for corners, window and door frames, blocking and braces. Set aside the crooked stuff for short pieces. Here are some more handy framing tips.
