I needed a jig to allow me to cut consistent thin strips away from the fence and the potential for binding and possbly nicking the fence. I have the Grr ripper but sometimes need a strip too narrow for this jig.

I saw this in Shopenotes or similar and never got around to making it.
It's really simple and only needs a routed slot and a bolt to carry a small bearing on the nose.

I picked up the miter slot fittings from Workshop Supply here in Canada.
You can fine tune this with measuring bars and cut strip after strip just by moving the fence in to the bearing surface.

If you use the Grr ripper you can set it way back and set the gripper up ahead of it to carry the cut through the blade.

My Adventures in Woodworking: Small hinge mortise jig

My Adventures in Woodworking: Small hinge mortise jig

Small hinge mortise jig

I've been struggling with fitting brass hinges into softer woods that I seem to work with today against my better judgment.
By the time I have the mortise cut for the hinge I find that usually a portion of the mortise has either fallen away, been crushed by my chisels, or a combination of both leaving an unsightly gash into which I have to place my hinge.
I've been looking at this jig as outlined in ShopNotes volume #12 No. 74.

The principle of this jig relies upon your router having a square base with exact sides. In my case I am waiting for a new router and used my roto zip that happens to have a 4 inch base attached from a previous job.
The jig relies on the four-inch base and the use of 1/4 inch carbide router bit to shape the mortises.

The first thing you need to do is determine where you need your hinge to sit in the wood. I laid a couple of hinges up as shown and marked their positions with a sharp pencil.

Next I opened the gate on the jig and fitted each hinge to the exact opening. Next the depth of the hinge was set using a side gauge on the jig.

Once the frame is lined up with the dimensions of the hinge the depth of cut is set for the router bit to match the thickness of the brass hinge being used. I actually made the mortise inset slightly deeper than the hinge so I could lightly sand away the milled edges giving me a cleaner mortise .
The last picture pretty much speaks for itself.
As shown, a 2 1/4 inch mortise on the left and the three-quarter inch mortise on the right and both are more than acceptable by my standards.
