How to make the edges for door hinges?
 

I need to grind the spaces on the door for hinges. Which tool to use? I am thinking about of the bit below. Anyone know which is better?

I thought you used a chisel?

Maybe the top one in a router.

Got a template kit at Lowes when I got the door... a whole $1 more than just the big azz drill/hole saw for the handle... comes with a template, follow the edge around wiht a chisel, remove template, get the inner part w/ chisel.

Bought 2 doors ($17 each), one to practice on. After a few tries, did the "real" door w/ no issues and it doesn't look like a drunk redneck did it (I was only a little buzzed...)

Car door or wooden door?
Wooden door- a router bit would be the answer.
Car door - a dremel carbide bit like you show would work.

Yep, using a chisle is the correct way to do it. But I got this

a month ago and use it instead. It can be used as a plunge saw and chisle, plus makes REALLY fast work of it.

If you have a router, you can buy a door hinge mortising kit from most hardware stores.

If not than a chisel should do the trick.

Apparently, there's also a cheap tool called a Butt Marker that can do part of the job.

Rout out - I've used a dremel with a router attachment to great success. Zip zip done.

I prefer a sharp chisel.

He can't be talking about a wood door. Maybe a car door, maybe a metal passage door.

We need to know more.

For wood doors chisels are Neanderthal tools. However, I keep 7-8 in my bag. Used chisels today in fact putting in a dead bolt. Wasn't worth draggin' out the router and templates.

Like the others said, a nice, sharp chisel. Put hinge where you want it to go, Draw outline with pencil, chisel. I'm not that good, but it still only takes me a few minutes to do.

Chisels are hand craftsmen's tools.

Neanderthals with power tools generally don't know how to use them.

ahh, I have this tool. Bought it while back, used once and throw it somewhere. I'll try it.

It's a interior house door that I was asking about.

I was hitting it with a chisel slightly and found that the "paper" type of interior door, box type, doesn't take chisel very well.

Thanks guy.

Chisels are for real craftsmen. I do have a nice and sharp set somewhere bit I use it once in a blue moon. Router would be the tool to use there. Set the depth and cut away. It should take about 15 second of cutting time. That Bosch is a great tool, and I have one, but I would not use it for your application. A chisel would be my second choice if I did not have router.

Look, I tried the chisel first but it doesn't work well. The door is the interior box type door, which is paper type, not real wood. The chisel doesn't cut in well. I did try the tool a little. It doesn't work well either but looks like it's better than chisel (for this type of door). I wish I have a router, but this is minor.
Thanks.

Well, I owned a pre hang door shop. I guess hanging a few thousand makes me unqualified.


Cheap cardboard doors so have crappy wood on the edge. It takes a scalpel sharp chisel to cut that balsa like wood. Mostly it likes to compress.

You idiots that won't move into modern society can continue to work in your caves with torches for light. I mortised hinge gains (wait, do you know-it-alls even know these terms?) with a chisel in 1970. How many of you had a tool belt then?

Pffftt.

I use a router, as I keep my chisels as sharp as a potato. They get sharpened (poorly) every decade or so.

They make butt hinge for cabinets that don't require mortising - the hinge material is 1/16" and interleave. I wonder if they make anything similar for interior doors?

..

They make a 3 1/2" non mortise hinge but I would NOT use it on any type of doors beside light weight cabinet doors. Why are you asking?

If I were trying to cut the edges and not really confident, I would mark for location and screw the hinge to the door exactly where I wanted it. then I would trace it with a utility knife or numerous times to get a sharp cut line. If the edge of the door was veneer, I would do the same thing. If I needed a really sharp chisel, and didn't know how to get one that sharp, I would just go out and buy a sharp one. Remember, do not set the hinge at the same spot on the door as you do on the jamb, or the door will bind on the stop. You need 1/8 inch clearance on the hinge side.

If you don't have sufficient clearance, most likely the door will bind and strain the hinge screws. If it doesn't bind now, it will when you paint it.
