Tools required :- Wood chisel, hammer, pencil, various screwdrivers, battery / power drill, small drill bit, wedges, dust sheet.
When the new door is cut and planed to size it is ready to have the hinge positions marked out. The hinge recesses on the door frame and door edge can also be cut using your wood chisel and hammer.
Place each of the hinges on the door frame where the originals were fixed in place, mark out around the new hinge with your pencil and cut out an appropriate recess to suit the new hinge with your wood chisel and hammer (see Fig 1). Whenever you are using the wood chisel, hold it with the bevelled edge facing the wood that will be removed (see Fig 2). Mark the fixing holes of the hinges on the door frame and drill small pilot holes (1/8″ 2mm) as straight as possible, for the screws, to reduce the chance of the wood splitting. Fix the new hinges in position, preferably with cross head screws.
Use a wood chisel with the bevelled edge against the wood that is to be removed.
Position the new door against the door frame, resting it on wedges at what will be its final fixed height (see Fig 3). The hinge positions on the door edge can now be marked out, try to get some assistance to hold the door in place whilst you mark the door edge. You can now cut the appropriate recesses in the door edge to accommodate the hinges, as with the door frame, mark the hinge fixing holes and drill small pilot holes for the screws. Now you are ready to hang the door in position (see How to hang a new internal door in position).
