This instructable demonstrates how to readily handle the early stages of deck construction. The meat of the procedure is to construct a simple (but square) "alignment frame" that is hinged to two temporary vertical boards that are mounted on the ledger board. The alignment frame keeps the concrete piers and wooden posts "perfectly" aligned during the first steps in the deck building process. The frame also supports and aligns the posts during the installation of the rim joists.
I added a step by step (typed) procedure at the end of the video.
The included video (below) covers the "front" deck of the house. Here's a link to a companion video that describes the building of the back deck - "Back" deck video
All the pictures shown in the video were BI (Before [my] Instructables) so definitely not as comprehensive as I would like. However, the written step by step procedure (at the end of the video) should help make up for the "missing" photos.
