In construction and carpentry, ink lines or chalk lines are used to mark long, straight lines. Shorter lines can be drawn using a straight-edge, but ink lines are extremely useful when needing to mark longer distances.
All major phases of construction require straight, clearly visible lines to serve as reference points. Because of this, one must learn how to properly utilize an ink line in various settings and environments.
For example, concrete and wood are 2 typical substrate materials where a long straight line might be needed. You might be wondering how and if it’s possible to pierce concrete with an inkline needle anchor.
The answer is yes. There are different anchor tips designed for different materials. Concrete anchors need to be tapped into the concrete with a hammer, while those designed for wood can often be pushed in by hand. You can also simply hammer a concrete nail into the concrete and use it as an anchor as well. (See image below.)
The ink line is itself a relatively simple tool, but using it effectively can sometimes prove to be a challenge. Here are some tips and pointers you should keep in mind to put you on the straight and narrow to becoming an ink line pro!
– Never bend the anchor needle from side to side while it’s lodged in the material. Whether it’s to dislodge it or to tweak the position of the line, forcibly moving the anchor laterally, while the tip is planted in a hard material can crack the tip, or at the least bend it out of shape.
– Unless the material is considerably soft, you generally won’t be able to sink the anchor tip all the way down to where the line meets the material surface. This means that unless there is a spring-loaded mechanism that pushes the line down to the material surface, there will be a gap between the material surface and line, making it difficult to accurately determine the true position of the line in relation to where you want it to mark. In such cases, wrap the line around the needle once or twice toward the tip of the needle before pinning.
– Remember that ink lines can “bend” or snap in a parabolic shape if you don’t pull and release the line vertically in relation to the then imaginary line you want to mark. The longer the distance, the less tension there will be in the line, and the more critical it will be to snap the line as near to vertical as possible. This problem is compounded if either anchored end is in a floating state.
– Both too much ink, as well as too much water diluting the ink, will result in a thick splash when snapped. For obvious reasons, this isn’t conducive to the purpose of the ink line and should be avoided. Several drops of water can be added every other refill, but continually diluting the mix will result in the line becoming less and less discernible.
– Be sure there are no uncovered finish materials near where you’re marking. The inkline can stain and ruin anything within its splash-radius. This is especially true when marking at higher points, where splash residue will travel further.
The Differences between an Inkline and a Chalkline
– Chalk can be washed or rubbed off, whereas ink is more permanent. The pros and cons here are fairly obvious.
– Chalklines leave thicker lines and are useful for ballpark markings such as for fastener positioning and pitch etc, while inklines leave sharper lines, better suited to tasks requiring precision.
– Take care when using darker colors for marking drywall, as it may show through thin, lighter colored wallpaper.
