Building Your Jig Table:   "One of the fundamental necessities for building an airframe is the Jig Table.  There are numerous ways to build a jig table, and the dimensions of you table will be dependent on your plans.  Whatever the design or size, all tables need to be constructed so they are stable and flat."
Leveling the Table:  "Leveling can be accomplished using a homemade water level.   It’s inexpensive, easy to use, and very accurate.  If you try to use lasers or other levels, you will find yourself frustrated."

Tubing Storage:  "Once your order arrives, perform a good inventory.  It’s a common practice to construct a rack under the top of your jig table to store your tubing.  Just use some small pieces of board to make this."
Materials:  "I also opted to use cheaper 3/4” Oriented Strand Board (or OSB) for the top of my tables.  I then covered the OSB with 1/4” birch panel.  This will give you a finished top that can be easily replaced to a new condition for about $12 to $14."
Marking Tubing:  "It’s also a good idea to mark smaller pieces of tubing with different wall thickness, especially if you don’t plan to use them for a while."
