Ok, I have a dumb question to ask and it’s three hours before I can call Van’s.   I was hoping to get a response off the list a little quicker.  

   

On page 25-5 of the fuselage plans, you mount two hat stiffners to the F-1004B center section bulkhead.  Per the plans, you remove the hatched area to allow access to buck the rivets on the lower flange of the F-1004B center section bulkhead.  No problem so far.  

   

However, the bottom #12 hole underneath the hat section on the right side is riveted already and the left side isn’t.   These are one of the massive rivets that were pre-riveted from the factory.  I’ve spent the last hour looking ahead in the plans to see what might go into this hole, but can’t find anything.  I’ve looked at a dozen sites looking for build pictures, but this area  is obscured in all the photos by the hat stiffner.  

   

So my questions are:  

   

<![if !supportLists]>1.       <![endif]> Is the center section bulkhead correct?  Is only one side supposed to be riveted already or both?  Again, I’m referring to the large #12 hole at the bottom and underneath the hat stiffner.  

<![if !supportLists]>2.       <![endif]>Step 3 refers to riveting something later, so what page in the plans highlights that step?  I can’t find it.  

<![if !supportLists]>3.       <![endif]>What goes into the left hole?  Am I missing one of the large rivets?  

   

Thanks,  

   

Bob

I'll give this a shot.  Step 3 says that you need to cut the hat stiffener to be able to buck the rivets in the flange, so these are the rivets that will rivet to the bottom skin of the airplane.  It is not referring to the spar/center-section itself.  If the #12 hole you are referring to would be covered by the hat stiffener if you didn't cut it, then I think they probably missed a rivet, especially if the hole is open on one side of the plane and closed on the other.  It is possible they just missed a rivet.  I think putting a #3 bolt in that hole should take care of it, but I don't have those parts here to compare.  Maybe someone else who is closer to this section can help better.

Bob,

 Underneath my hat  stiffeners I have Van's installed rivets on both sides.  I don't see  anything in step 3 of page 25-5 that says you rivet something  later.

Thanks to all the replied!  

   

Just got off the phone with Van’s.  I am indeed missing one of the large rivets on the center section bulkhead.  They offered two fixes.   The first was to send me a rivet and attempt to set it with a really large hammer.   I opted for the second choice, which was an AN3 bolt of the appropriate length.
