Line retrieval has 5 gears to save your time on your jobsite. The Tajima Chalk-Rite CR301JF is a jam-free snap line chalk box. Secure the hook end reel out the string and pull it taut then lift the string straight up and let it go. When you need to mark a long, straight line on a wall, ceiling or floor, use a chalk line (see Photo 3). This is a great way to align fence and deck posts, check for sags in floors, or level the grid for a suspended ceiling. By measuring between the string and wall at intermediate points, you can determine how far to push the wall in or out to straighten it. For instance, to see if a wall is straight, tack two spacer blocks of the same thickness at the ends of the wall and stretch a string between the two (Photo 6). Measure the gap between the test block and string.Ī string pulled taut is a good way to check straightness. Stretch a string between blocks at each end of the wall.

downward crown will wind up with a full 1-in. upward crown will wind up straight if the center settles 1/2 in. With floor joists, a small crown is actually desirable -just make certain you always position the crown up. When building a wall, have all the crowns on the same side, so the finished wall doesn’t have a wavy surface. A slight crown is almost inevitable, but you should reject boards where it is very noticeable.

You can detect a hump, or “crown.” as it is called by carpenters, by sighting along the length of a board (Photo). The naked eye is as good a tool as any when it comes to judging crooked vs. You can always fix things with a jointer and a planer. Selecting high-quality material is the first step toward projects that are straight and true. If it’s too crooked, nothing built with it, on it, or next to it will fit well. Wood performs amazing contortions as it dries, so be picky when you buy your lumber.

Here are detailed instructions at how to do it. The little extra time spent up front will pay off handsomely all along the way, with less wasted material, fewer hours spent on the job, and a lot less frustration.

Starting off straight, square, level, and plumb (vertical) is the most crucial step in assuring that your projects turn out looking great. Well, chances are, it was at the very start, with lumber that wasn’t straight, corners that weren’t square, and a floor that wasn’t level. on the other none of the drywall fits quite right and now, standing ankle deep in wasted oak trim, you wonder where you went wrong. Beautiful oak doors stick and bind that last row of floor tiles tapers from 4 in. Your dream family room has turned into a nightmare. Remember the plumb bob may be a useful guide if you’re not sure on a subtle slope but it’s not a given, and it also won’t help you determine if the putt is up or downhill.There you stand, frustrated and disappointed, in the middle of your half-finished basement. If it appears to the left of the cup, the slope should take the ball from left to right. If the shaft appears to the right of the cup, the slope you are on should take the ball from right to left.

If the shaft also covers the hole, the putt should be straight – the ground you are standing on should be level. Hold the putter up, as described above between thumb and forefinger, towards the end of the grip if you can, covering the ball with the shaft. Stand about 10 feet or so behind the ball (maybe further back for longer putts) so you are looking directly through the ball to the hole in a straight line. You need to gain a good understanding of how the plumb bob method works before you put it into practice on the course, so you should spend some time on the putting green learning the process. This is very important as it’s how you must hold your putter each time in order to have a true vertical line when plumb bobbing – It won’t work otherwise. Look where the putter head is positioned and remember that. Twist the putter round between thumb and forefinger to find the point where shaft and the chosen vertical are level. Find a known vertical, like the edge of a building, and hold the putter up so you can compare the vertical with the shaft lean. It likely won’t do that automatically as the shaft will generally not go into the very centre of the head meaning there will be some tilting. In order to plumb bob effectively, you have to check the shaft of your putter hangs absolutely vertically when you hold it lightly between thumb and forefinger on the grip.
