I have a Porter Cable that I’ve used for years. It does mulitple sizes and square and round corner hinges. Was around $20. If you have lots of doors to do Porter Cable makes a nicer model but it’ll set you back more $$$

It’s easy to make your own as well. But the Porter Cable works well, and is fairly cheap.

I don’t know for what type of hinge; but if its for doors; as in house doors then you can find a good repeatable jig at
“Norfield tool.com” they are in chico,ca,tools for prehang door companies

Look at the Mortise Pal. A bit expensive but a good store bought jig I suspect. It is completely adjustable.

I own a Mortise Pal and like it very much, but it would not work for making door hinge mortises.

I always make my own jig for hinge mortises. It’s very easy to do and I see no need for any plans to make them.

I use a simple piece of plywood and make two cuts in from the side with a band saw. The distance between the outside of the cuts is according to this formula –

Distance between the outside of the cuts = H+BU-BI

where H = width of hinge BI = Diameter of bit BU = diameter of bushing

I usually use a 3/8” bit and a 1/2” bushing.

I make the cuts a little deeper than I think I will need and then make a cut across the ends to form a square.

I set the hinge in place and place the plywood in place such that the gap on all 3 sides is equal to 1/2 of BU-BI and I make a pencil mark on the back underside along the edge of the door.

I then clamp a 2×2 on the underside of the plywood along that edge and screw it to the plywood from the top. Keep the screw heads away from where your router base will be.

Then clamp the 2×2 to the door at each end and cut your mortise.

I can make one of these in less than 5 minutes. I usually don’t keep the jig for future projects because I can make another very easily.

Note 1 – Sometimes, I don’t bother with the 2×2. I just screw the plywood directly into the edge of the door temporarily. No one will notice those screw holes (especially if I fill them with wood filler).

Note 2 – If the hinge has square corners, finish the corners with a chisel.

I am making boxes and making my own wooden hinges and they vary in size for every project so something adjustable would be nice I saw the video for this one that is a homemade http://www.shopnotes.com/issues/74/videos/using-the-hinge-mortising-jig/ but i couldn’t find the plans here is one that rockler sells but it seems a bit pricy http://www.rockler.com/product.cfm?page=2290

Guss, Making your own jig is not that hard. I mentioned the Porter Cable because it comes with a nifty router bit that will cut a sqaure corner, no chisel required when used with the adjustable jig. Comes in handy when you’re doing the larger commercial doors hinges. I think that you can buy the PC router bit alone as a replacement bit.

the model 59370 is the one I’m using these days. A 3” hinge is as small as it’ll do.

Not sure if it is what you are looking for, but if you want to build one yourself, I have a set of plans that I could send you. critter2722@yahoo.com

+1 on the WOODSMITH jig … I built one and use it with a BOSCH COLT … it is dead on accurate.
