Template question

I am a mug for volunteering to do this job for a friend.

The task is to frame a mirror. No problem with the base and the most of the two sides, they are just about complete, but the top is an arch.

The frames is about 2 inches inches wide. I have used the mirror itself and managed to cut a template for the inside of the curve. The problem is that I can't use that curve and a guide bush to make the outside cut because of the width of the frame.

Any suggestions on how to make the outside curve please?

Torb is the problem that the radius is different on the outside edge or is it some other problem?

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Charles,

The radius of the outside edge should be 2 inches bigger than the radius of the inside edge. The problem is that I don't have a 2 inch bearing or a 2 inch guide bush.

It wouldn't be that hard to make another template from the mirror that is 2" larger. Just use a combination square or a pointed dowel against the mirror at a 90* angle and follow around the mirror at 2" farther out. You would have to noticeably deviate from 90* for it to be noticeable on the frame, something on the order of 10*.

Following on from what Charles just said, a 2" sq. block of wood, with the pencil in a small vertical groove on the outside, and a bit of a vertical concave shape on the inside...
Just slide it around the perimeter to layout the new template. That'll follow any curve fairly accurately.

Thanks to both of you. I used a bit of dowel with a pencil stuck to the end and a small nail at the 2 inch mark. Worked a treat.

The best solutions are the really simple, really cheap ones.

Cut a circle/wheel of wood that has a 2" radius and a center hole to accept the lead of your pencil. 1/4" MDF works well for this. Put your pencil through the center hole and roll the circle around the curve. You'll have your curve.

That's very true Charles, I heard that the US spent over 3 million attempting to design an ink pen that would write in zero gravity. The Russians used a pencil.

That's funny and sad at the same time.
