Installed basic carpentry hinges may strain the wood to which it in attached. Problems are likely to develop with hinges that support heavy weight. Hinges used primarily as pivots, as on the lid of a box, seldom need repair.


Sometimes hinges must be removed to repair other parts of a piece. A problem with the hinges themselves or the need for minor adjustment, replacement, or a change in position may also require their removal. In each case, there are certain procedures to follow, many of which also apply to other kinds of hard-ware, such as fasteners and handles.

When disassembling a piece of furniture, simply remove the screws from the hinges. But be careful not to damage the hinges themselves or to mar the surface around the hinges. You may discover at this time that the hinge or hinge bed needs repair: otherwise replace the hinge in exactly the same position. Hinges that do not pivot smoothly may need a drop of household oil. Screws that require tightening or replacement. If a hinge pin is lost or broken and yell can not cut a dose substitute from a nail, replace the entire hinge. When buying a new hinge, take the old one with you to compare type, style placement of holes and other features.

Screws usually work loose because the holes have become enlarged. Substituting screws Of a slightly larger size may solve the problem stir there is a risk of splitting the wood and compounding the trouble if you use too lam go a screw. It is safest to fillin the holes by one it the method redrill the screw holes in the same places and insert new screws of the original size. You can also replace the hinge with one having differently spaced holes. Fill in the original holes, then drill new ones to lit the new hinge and install it.

Split hinge bed

Before screwing down a loose hinge examine the wood underneath. If the hinge bed is split, mend the split with glue clamp it, and let it dry before replacing the hinge. To provide stronger support lose hinge on a heavy piece, such as a table leaf, reinforce the damaged bed with a shim, in addition to repairing the split. Then, screw the hinge down on top of the shim.

A hinge bed may become so damaged that you must move the hinge to a new position. Since hinges work in sets of two or more, this generally requires moving more than one hinge to maintain symmetry and balanced support. Fill in the old hinge beds and screw holes with wood putty cm chips and glue, If the old beds will show, refinish the wood. Where the old beds are recessed, they can be leveled by using a shim made of a matching wood after which the surface should lie refinished.

Aligning basic carpentry hinges

When marking the positions for new hinges, you must carefully align the elements being lunged, such as a box and its lid. After deciding on the placement of the binges secure them first to one part, say the lid. Then, line tip the lid with the box again and carefully mark the second set of hinge and screw hole position in the box. Drill clot holes, and then screw the hinges to the box. Installing a hinge flush with the surface requires an additional step. First chisel out a recessed bed, as illustrated below; then, install the hinge.
