Welcome Bob,
Glad you found our forum.
As far as your question on doors and windows. One of the members here,
Grant Whipp,

might be able to help you.
Another good option, is to take your question down to the " Teardrop Construction, Tips and Techniques" and ask there. You will probably get more replies.
See you around.
