In my antique house, years ago, there was an apartment upstairs so a couple of the interior doors had deadbolts installed. On a recent paint project, I decided to patch the holes where the deadbolts were installed. I also was frustrated with the old latch hardware and door knobs so I decided to patch those holes where the old hardware was and install modern hardware. And what better way to do this than with my MFS400 and OF1400 router?
Here you see the MFS all set up. I made the opening just a little larger than the hole. To set the depth of cut, I move the router to the side and with the power off, plunge the bit down until it rests on the surface of the door.
And then with a half inch brass bar, loosen the plunge rod and insert it between the rod and the stop and then tighten the depth rod.
The MFS has some adjustable angle stops underneath, they help keep the jig in alignment
The door is narrow so it was awkward to clamp, with the stops pressed firmly against the door, I used and F clamp on the left and a k-body on the right to help keep tension on the alignment stops.
After I made the cuts, the result was a perfect half inch deep mortise. For the uninitiated with the OF1400, this is how clean they cut, no debris left behind, excellent dust collection. What a pleasure to use!
I reset the mfs for the smaller mortises and also set the depth for 1/4" and made the cuts for the knob and keyhole
I milled up some poplar dutchman and tweaked the size with my shooting board and block plane. I also squared up the mortises with a chisel.
After the glue dried, I planed the dutchmen flush with the door using my LA jack. Very pleased with the way they turned out. The joints are air tight, no doubt the patches will be invisible once I paint them. An easy task with the MFS!
