Using pre-drilled holes
First, establish the size of the pre-drilled hinge plate holes in the cabinet. They are usually 5mm or 3mm. The scribe jigs have two location pins which are stepped from 5mm to 3mm. If the holes are 5mm diameter, use the jigs as they are. Locate the jigs into the holes and secure using the bugle head screws provided. Do not over tighten. Place the prepared fillet into the jigs ensuring the clean edge is tight to the jig and secure with the clamps. Scribe your line and cut to the line. You will discover your fillet will fit neatly first time and the need for caulking is minimal - if at all.
If the hinge plate holes are 3mm diameter, attach a shim over the location pins and proceed as above.
