After getting some sleep and recovering (somewhat) from the first leg of our priming marathon, I am ready to spray the AKZO epoxy primer on the wing ribs.  But first, I needed to re-work the spar end rib (W-707F) that I incorrectly countersunk a couple of days ago.  I am not going to beat the dead horse here, but what I wanted to bring up here is that I had purchased a micro-stop countersink with a half skirt (cage).

As you can see below, it allowed me to use the countersink cage even when countersinking close to the bend.  Worked well, cost me $16.95 from the Yard Store.

 

Alright, enough about fixing my screw-ups.  One thing I had to figure out before I started priming was where was I going to put all the ribs to let them dry.  Up to this point, room hasn't been a problem as the priming sessions and parts have been small.  However, this is a lot of ribs to prime.  What I did was take my 10' 4" x 4" that I am going to use for my wing stand and pounded in some 1 1/4" roofing nails to hang the ribs on .  I spaced the nails approximately every 10" to prevent the ribs from banging together.

Just another close up shot...  I think that the 4" x 4" timbers may be a little over kill here.  That's okay, I actually bought them for the wing stand...

Fast Forward>> to the end product.  I primed one side and then hung them on the nail to dry.  When they were dry to the touch, I primed the other side.  Because the ribs like to sway a little on the nail, I always put the dry side of the rib facing the 4" x 4".  This worked really well. 

Here's my "rack of ribs".  The statistics for the priming marathon include:

• 28 outboard/inboard ribs primed
• 10 leading edge ribs primed
• 5 hours of spraying primer
• 16 hours of total effort
• 8 scotchbrite pads
• 18 sets of latex gloves
• 1/2 gallon of Alumiprep
• 8 oz of Alodine
• 16 oz of Acetone
• 1/2 gallon of AKZO Epoxy Primer
• Being done.... PRICELESS (Actually, around $60 for all of the supplies)

I am a day ahead of my "planned" schedule.  If all goes well, I will have the wing ribs riveted to the spars and in the wing stand before I go to work on Monday.
