How to Hang a door Step 1 Preparation Using a level, check that the frame is built in properly square. Measure the door opening, then trim and sand the door’s edges, until there is a clearance of 2 mm all around the door. To check, wedge the door inside the frame, making allowance for floor clearance.
Step 2 Hinges Traditionally hinges are set 150 mm – 175 mm from the top and 200 mm – 250 mm from the bottom of the door. With a hollow core door, locate the lock block and fit the hinges to the opposite edge. With the door on its side, place each hinge on the door - spindle outermost, projecting from and parallel to, the edge of the door. Trace the hinge’s outline, also mark its thickness on the door’s face. Carefully chisel out the hinge recess so the hinge will sit flush with the door edge. Mark the screw holes and drill pilot holes.
Step 3 Hinges continued On the frame, trace around the hinges in the same way. Wedge the door in again to check on accuracy, then chisel the hinge recesses in the door frame, and mark and drill pilot holes on the frame. Screw the hinges to the door, wedge it in position again and screw the other leaf of each hinge to the frame.
Step 4 Lock Position the body of the lock against the side of the door (on the lock block, when dealing with a hollow core door). Mark its top and bottom and transfer these marks to the edge of the door. Mark the positions of the keyhole and handle spindle, through the body of the mortice lock. Drill these holes.
Step 5 Lock continued Mark the centre line of the door edge to help you trace the rectangle for the body of the lock. Drill a series of sufficiently deep holes and chisel out excess wood, keeping sides straight. Smooth the inside and insert the lock. Trace around the front plate of the lock and cut out the recess to take this plate. Screw it on.
Step 6 Handle Fit the spindle, then screw the door handles and lock covers on to the door.
Step 7 Striker Plate Close the door and mark the top and bottom of the door catch and the lock bolt on to the door frame. Transfer these marks to the edge of the frame and cut out the necessary holes. Cut out a recess in the frame edge to take the striker plate and screw it on.
