Forum member Ackattack coordinated and many people contributed to the index. I don't have an assembly manual yet, but I have the thread bookmarked for when I do get one.

The link to the index is in the first post, and there is mention on one of the subsequent posts that in order to see the index you need to go to Tab "Sheet1"
The manual is available in both paper and CD versions, I will probably get both.
