Framing an Eyebrow Window

I need to frame for an eyebrow window and have never done one before. Anyone have any good sources for learning how to do this? Do any of the Taunton Books cover this? Thanks.

What do perceive as being a problem? What are are you not sure about? I can answer your questions for you. I don't know of any book though. They are really easy and after ya do the first one.......

If you have specific sizes I can draw the framing detail out for you and send it along with full explanations. Or I can just draw a made up size, but I think using your measurements is best.

I guess the fundimental question that I have is really simple....how do I translate the top curve of the window onto the sloped roof that the mini-dormer will protrude from (short of using a long pencil!). I know there must be an easy way to do this...I just can't think of it.

A level or some kind of straight edge could be used to scribe that radius on the main roof might work for you. Just a thought , Dave

Walt,
How did you make the window opening on the wall? It would work the same way for the roof unless you traced the window. But you frame before the window arrives so I wouldn't think you traced the window. I can answer your question. I'm just trying to get a feel for your style.

Billy:

For a window on the wall I know the rough in size and know that the sides are straight. For a dormer (even a retrofit) the task seems simple to me because the lines are straight. I can figure out where the dormer will intesect the roof and snap chalk lines...them break out the saw. This is more complicated (to my simple mind) because of the curved lines involved. The idea of using a level sounds like it would work.

Regards,

Walt

Walt,
Do you have back issues ? There was a great article about 5-8 years ago in FHB on this subject. If you do have issues, do a search for "dormers" in the index of the FHB homepage. There are a number of entries under "eyebrow".

I think this book by Taunton has a good article oon framing a building an eyebrow window (at least the old version at my library did).

March 2001 issue of JLC has the article "Raising the Eyebrow Dormer"--very clear illustrations.

Thanks, Mongo! I went to the JLC site and couldn't get a hit on the search, so assumed it was too current for them to show the article...i'll get the hang o' this yet! ;-)

Walt,
You never gave me details, so I'm reaching. This is a typical drawing of two different eyebrows. Not perfect, but enough to get an idea. I am doing 3 eyebrow dormers on the house that I have been posting in the Gallery recently. They are not sloped downward though. They have arched widows in the front and the dormer roof is arched but they are not pitched with the roof. So mine are different than the ones I have posted. Built different and look a little different. I don't know how yours are supposed to be so this is what I posted.
