I just tried fetching it using wget on windows 7. I got the correct index.html and was able to convert it.
Get wget at
http://gnuwin32.sourceforge.net/packages/wget.htm
After installing it, and assuming you took the defaults, in a command box, run
Code:
"C:\Program Files\GnuWin32\bin\wget" -P c:\unclerod http://uncle-rods.blogspot.com/
cd c:\unclerod
ebook-convert index.html unclerod.epub
Change c:\unclerod to the directory you want the index.html to appear.
