I am planning to make a double set of 8′ X 36″ mohogany exterior doors i have two questions. sketch up should be attached
Am I better off making the frame out of laminated 4/4 and gluing the cupping faces together or should i dimension down 8/4 stock.
next what method will give me the best r-value where glass is involved.

Your attatchment did not open for me. However I have used 8/4 mahogany for doors, and never had a problem.
Having said that, It is very important to know what to look for in the wood that leads to warping, cupping , and twist, and especially reaction wood, which the african type that I have seen lately seems to have plenty reaction wood in it.
Corey,
If you want others to be able to see your SketchUp drawings, you should save them in a universal format, such as JPEG (jpg).

can't seem to save as jpeg
To save your Google SketchUp as a JPEG so others can view it try this: File>Export>2D Graphic. Then name it and save it in the location of your choice.

What is your experience level? I am well into my door project (only interior doors), and I am not sure I would have attempted this now had I done all the research I have to get to this point. There is a big reason why custom doors cost what they do. Anyway, I went with Stave Core after doing all the research. If solid, try to find quarter sawn. Take a look at the wood web site. If you can make it through the arguing on that site, there really is a lot of great discussions about all the pro's and cons. R Value for glass, best you can find is R8 as far as I know, but if you are contemplating solid rails/stiles is probably does not make a lot of difference. Artisan Custom doors has insulated stave core rail/stiles for one type they build.
Best of luck. I found a great of good advice from many on knots.
Last fall I made an entry door out of walnut and I glued up a sandwich of two pieces of 5/4 stock and a piece of 3/8 inch thick wood that was a mahogany lookalike. The Walnut I used was not thick enough after face jointing and thicknessing to get it made out of one piece of 8/4 stock plus I did not have to worry as much about hidden flaws in the figured parts of the wood. Anyway to make a long stroy short I think gluing up your stock will give you more stability.

Hi: I made a cherry entry door that has stayed perfectly flat and dimensionally stable for over 10 years. I resawed and laminated 8/4 stock forthe rails and stiles and netted a one and 3/4" thick door. I would certainly do this again considering the perfect resultl. P.S. I used a vacuum bag for the laminating.
