It can be adjusted by sliding the metal across the wood and locking it in place. Choose from our extensive selection of trammels for all your measuring and layout needs at HomElectrical. Learn more about Trammels! A trammel is usually used when you have to draw a big circle or arc that cannot be handled by a regular compass. Some of these trammels can be used with a beam to make up a beam compass. This is great for template work. Trammel points that can fit a range of bar sizes are superior.

The eccentric-point type also holds a wooden pencil for paper pattern layout. Fine adjustments are easily made by rotating the eccentric point. Use a superfine point marker or pencil if the part will be subject to high stress. High-strength materials and tight-radius bends fail along these little stress risers.

In addition, slightly round the corners on a plate surface. Skim over flame- or plasma-cut edges with a sander or grinder to eliminate potential crack-formation points. You can flip your layout to the opposite side to keep cutting with the stock on the outside of the machine. I made mine with little rollers so I can easily slide it down the length. The rollers are spaced equidistant from the center of whatever width bar is used as long as both rollers are touching.

If you have one of those cast aluminum combination squares, do yourself a favor and throw it away. Better yet, break it into pieces so nobody pulls it out of the trash can, where it belongs. Normally, I use the long blades as straight edges or to set distances off an edge.

You have to be careful and have a fine touch when using a long blade to check squareness. How do you measure a compass? Step 1: Prepare the Compass Arm. Take the nail and push it through the string. Step 2: Prepare the Center. Find where the center of the circle will be. Step 3: Prepare the Drawing Swing. Lay a tape measure out, with the 0" mark at the center of the circle.

Step 4: Draw the Circle. Step 5: Reveal the Circle! How do you draw a big circle? To draw a circle, insert the nail in the first hole, pass the tip of a pencil through the second hole and draw your circle. With this technique, you can make a circle of any size. If you want a circle eight feet in diameter, all you would need is a longer piece of wood.
