How To Measure Trim For Windows
When measuring trim boards for cutting, fifty-fifty the pros make occasional mistakes of the "d'oh!" variety. And then have the time to measure carefully and recheck your measurement to be sure you will not waste product a skillful piece of molding. Following are some measuring tips. (For installing crown molding, which calls for specific techniques, see How to Install Crown Molding.)
Practiced advice on how to accurately measure interior trim during installation, from choosing and using the right measuring tools to using a story pole.
Checking Your Trim Tools
Start, examination to make sure your measuring tools are accurate. If you are working with a helper, have a measurement with ane tool while your helper measures with some other and compare your results.
A tape measure out's hook slides back and forth about 1/viii inch-the exact thickness of the hook-so that you get the same measurement whether hooking it or butting it. Test it on a chip piece to make sure the measurement is the same both means.
A level often goes out of alignment. Place your level on a apartment horizontal surface, note the position of the bubble, and so flip the level over. If the bubble is not in precisely the same position, it may exist time for a new level.
Otherwise, y'all will need to flip the level every time you measure and brand a line or concur the board in a midway position. Perform the same test while property the level against a vertical surface to make certain you lot are getting accurate plumb lines.
Framing squares rarely become out of square, just they practice get aptitude, which can throw off your measurements. Test yours against two factory edges of a slice of plywood. A solid bending square (also called a speed foursquare) is almost always reliable.
Keep in mind that a power miter saw or circular saw volition typically cutting a line (or kerf) about 1/8 inch broad. A hand backsaw will probably take a narrower kerf.
Proficient Trim Installation Habits
Work methodically to ensure that y'all measure and marker each lath in the same way. When using a tape measure, call out to your helper (or softly to yourself) the measurements.
If you apply a carpenter's pencil, take the fourth dimension to sharpen information technology cleanly then you can draw thin lines. Many trim carpenters prefer to use a standard pencil; others mark with a pocketknife instead of a pencil.
Depict a V rather than a single line, with the point of the V indicating the precise location for the cut. Then use a square to describe a line through the V, and marking the waste product side with an X to make sure you cut the correct side of the line (you want to cut so the line remains on the trim slice).
Dealing with Sixteenths
Counting upwardly sixteenths of an inch is ho-hum and often results in mistakes, so, for case, if the measurement is fourteen iii/16 inches, some carpenters say "14 and a quarter minus," meaning one/16 curt of 14 i/four. Others say "fourteen and a quarter short."
Still others say "14 and a quarter; cut the line," significant you lot should cutting off the entire width of the line (which tends to be near 1/8 inch broad). To indicate 14 5/16, utilize "14 and a quarter plus," or "stiff," or "exit the line."
When marker for a cut, use the simplest method with the fewest possibilities for fault. Often the best option is to hold a slice in identify against the wall and marker it rather than apply a tape mensurate. This method oftentimes works when one stop of the piece ends at an outside corner, but this will not work when you are measuring from inside corner to inside corner.
Before holding the piece in place, check to make sure the end y'all will not be cutting is square as you cannot always trust boards to come square-cutting from the factory.
When measuring for a door casing, scribe a line along the edge of the jamb indicating the amount of the jamb border you want to reveal-typically, ane/4 or iii/8 inch. Hold the vertical casing pieces in place and use the scribed line to mark them. Once the two verticals are in identify, concord the horizontal in place confronting the verticals to mark it.
Using a Story Pole
When installing a chair runway or other molding around the middle of a room's walls, you want all the pieces at exactly the same height. You tin practise this past drawing level lines, just that's time consuming. As long as your floors are reasonably level, using a story pole is easier.
You can make a story pole out of a piece of lumber or trim. Mark it with the acme of the moldings you lot desire to install. Hold the pole in position and mark the wall at various points or mark either end of a wall and snap a chalk line between the marks.
Hooking a Measuring Record
If a piece is cut at an angle on the finish you are not cutting, it will be difficult to claw the tape measure out to it. Instead, lay the trim piece forth a 1-by board, with its terminate even with the end of the one-by, and hook the record to the ane-by instead.
