Slide the Guide (4) onto the Main Frame (3) as in Image 1.
Slide the Clamp (1) onto the Main Frame (3) as in Image 2.
Place the Shaft (2) through the Guide (4) before attaching the cutter piece and before you attach the mortice jig to the door, as in Image 3.
Use the lock as a template to mark off the top and bottom edges of the lock body and faceplate. A and D mark the faceplate, B and C mark the lock body.
Select an appropriate cutter that suits the depth of the door and lock body. Screw the cutter onto the shaft.
Place the mortice jig to the door edge. Position the jig so that the cutter can move no lower than 5mm below C. Tighten the lower clamps.
Position the jig so that the cutter can move no higher than 5mm above B. Use the provided clip to stop the cutter from moving beyond this point. Tighten the upper clamps.
Place the lock between the guide and the depth stop. This sets the depth to which the cutter will enter the door. Tighten the depth stop with a grub screw.
DO NOT OVER-TIGHTEN.
CAUTION: Grease the shaft before you continue. If you do not grease the shaft, it will expand in heat and become jammed. Equip PPE and connect power.
Connect an electric drill to the shaft. Place one hand on the guide and feed the cutter into the door. Use a high speed setting on the drill. Then disconnect power.
Use the spanner provided to unscrew the cutter whilst holding the depth stop. Take care as this jig may be hot.
Now that you have cut the hole for the lock, you need to cut a shallower hole for the lock faceplate so that it is flush to the door. Select a larger cutter that is the same width as your lock faceplate. Push the shaft through the housing and carefully screw the cutter into place until tight.
Place the lock faceplate between the guide and the depth stop to mark the depth you will cut.
Re-position the jig so that the cutter can move within 5mm of position A and within 5mm of position D. Ensure the cutter cannot cut beyond positions A or D.
Carefully cut the recess so that the faceplate can sit within the door. You will need to square off the recess using a hammer and chisel.
NOTE: The T-Mech Mortice Jig can be used in various other situations. These include morticing
All maintenance should be carried out by a qualified professional.
The cutters included are carbide-tipped. Carbide-tipped cutters can be sharpened using a diamond whetstone.
Screw the cutter onto the shaft. You should only ever cut the flat side, never the profile side. When sharpening, only use water as a lubricant. Do not use oil.
Glide the cutter along the stone with light to mild pressure. Try to repeat the same number of strokes on both sides. This should be between 5-30 strokes. You can find useful maintenance tips online.
