Cutting hinge slots in door
Learn how to cut accurate slots for slot hinges in this woodworking video. How to Cut Mortises for Door Hinges with a Cutting a door hinge mortise with a door and the door jamb that mirrors the size and thickness of the door hinge. Oct 23, · Cutting Mortises in a door for hinges is an easy job with the correct tools.
How to Cut Mortises for Door Hinges with a Chisel
You can do this! If you use a door hinge jig, it will speed up the process quite a bit. Make this adjustment if you are using a laminate router only. Secure the jig in place. Use an existing door or jamb for reference if needed.
How to Cut Perfect Door Hinges
How To Get the Hinges to Lay Flush in a Door Frame When you install a door hinge, you need to make notches for it on the edge of the door and on the jamb, or the door won't close properly. These notches, or mortises, should be just deep enough to allow the surface of the hinge to sit flush with the wood. You can cut them by hand with a hammer and chisel, or you can use a router and a mortising template. The latter option gives cleaner results than doing the job by hand, and it's faster, but may not be practical if you're hanging just one door.
Using a Router 1 Support the door on edge between a pair of sawhorses with the hinge side facing up. These two measurements should be equal. If there is a third hinge, position it midway between the other two. Adjust it to the size of the hinge and tack it with double-headed nails or screws. Install a bearing-guided router bit into the router, and adjust the cutting depth to the thickness of the hinges.
Rout the mortise by guiding the machine clockwise around the template. Most templates are for hinges with rounded corners, so if yours has square ones, you may need to square off the corners with a hammer and chisel. Once you are satisfied with the fit, rout the other mortises on the door and in the jamb in the same way. Using a Chisel 1 Support the door between sawhorses with the hinge edge facing up and measure the positions of the hinges.
Make marks for the top of the upper hinge, the bottom of the lower one, and one or the other side of the middle one. Measure and make similar marks on the jamb. Adjust the hinge so the pin is flush with the surface of the door that is opposite the doorstop, and trace its outline with a sharp pencil. Draw a line along the other side of the hinge to mark the depth of the mortise.

Believe it or not, hanging a door is a relatively straightforward job. Even if you are a beginner DIYer, you can do this task with some basic instruction.
The one step of hanging a door that may be unfamiliar to you is cutting out the slots mortises for the hinges. This is typically accomplished with a hammer and chisel. It can certainly be done freehand, without the use of any additional tools, but it takes some time and some serious attention to precision to get it just right.
Door Hinge Jig If you are new to this task, or if you have several doors to hang, you might want to consider another method of cutting door hinge slots: If you use a door hinge jig, it will speed up the process quite a bit. And it will be worry-free, because the jig will guide your cut for you, eliminating much of the need to pay attention to precision. Think of a jig as a template. Before You Get Started: Depending upon the brand of jig you are using, the adjustments may differ slightly from the ones we are showing here.
If you happen to be removing an old door before you install the new one, you can use it as a guide to where to position the hinges on the new door. Practice a few times with your jig before cutting into the actual door. You can make a few practice cuts on a scrap 2-by Before placing the jig over the door, adjust it to accommodate the shape of your hinges rounded or square corners.
Round hinge corners on the left, square hinge corners on the right. Place the jig over the door. Secure the jig in place. Adjust the slider on top to accommodate the length of the hinge.
Automatic The slat lies flush with the wing leading edge until reduced aerodynamic forces allow it to extend by way of aerodynamics when needed. Sometimes referred to as Handley-Page slats. Fixed The slat is permanently extended. This is sometimes used on specialist low-speed aircraft these are referred to as slots or when simplicity takes precedence over speed. Powered Operation[ edit ] The chord of the slat is typically only a few percent of the wing chord.
The slats may extend over the outer third of the wing, or they may cover the entire leading edge. Many early aerodynamicists, including Ludwig Prandtl believed that slats work by inducing a high energy stream to the flow of the main airfoil , thus re-energizing its boundary layer and delaying stall. The actual effects of the slat are: The circulation effect The circulation of the downstream element increases the circulation of the upstream element thus improving its aerodynamic performance.
The dumping effect The discharge velocity at the trailing edge of the slat is increased due to the circulation of the main airfoil thus alleviating separation problems or increasing lift. Off the surface pressure recovery The deceleration of the slat wake occurs in an efficient manner, out of contact with a wall.
Fresh boundary layer effect Each new element starts out with a fresh boundary layer at its leading edge. Thin boundary layers can withstand stronger adverse gradients than thick ones. History[ edit ] A slats during landing Slats were first developed by Gustav Lachmann in A crash in August , with a Rumpler C aeroplane on account of stalling caused the idea to be put in a concrete form, and a small wooden model was built in in Cologne. In , Lachmann presented a patent for leading-edge slats in Germany.
However, the German patent office at first rejected it as the office did not believe in the possibility of increasing lift by dividing the wing. That year a De Havilland D. Licensing the design became one of the company's major sources of income in the s. The original designs were in the form of a fixed slot in the front of the wing, a design that was found on a number of STOL aircraft.
