Hi all,

  

  I am building an RV 8 and have one of the first pre-punch  fuselages.  Please reference drawing 78 if you want to see the spot.   I put the HS on and bolted it in place.  I then put the rudder on but found  the forward end of the rudder hit the rear fuselage top skin.

  

 I thought I had fit all this together before, but think maybe I had never  really bolted the HS down.  I double checked and think I have all the  appropriate spacers (just one 1/8th inch spacer on each side under the HS and on  top of the deck.

  

 I started filing down the nose of the VS to get it to fit.  It needs  about 3/8 of an inch to fit without touching the rear top fuselage skin.  I  took off all the skin in front of the bottom rib but will need about 3/16 off  that.  I think that the minimum rivet to edge distance will be okay, but  wondered if I have done something wrong.  It doesn't seem right,  somehow.  I thought I would see if anyone else has had this issue  before I file off something that I should not be removing.

  

 Thoughts?

  Had you already drilled the holes for mounting?  I put mine on too low

(with the rear top skin not on the plane) and so had the move it up and

re-drill (replacing the bars it bolts into).

Michael,

   I have a dash1 fuselage and the fit was the same as yours.  I was able to

  trim  the bottom  of the vertical for clearance and still have enough edge distance.

So Bill, do you remember if the holes in the VS and HS that bolt together  were pre-punched?

Hi Brian,

  

 Yes, there are drilled.  My vague memory is that I leveled the HS on  the fuselage but that the holes on the VS spar were pre-punched.  In any  event, there is insufficient room to redrill them and have adequate edge  spacing.

I sent an email to Van's.  Here is what they said:

  

 Michael,  This is not uncommon.  There's not much for lateral  loads on the rivets of that lower 

nose rib so don't worry too much about  edge distance in that area.  As long as you've got a 

little 'meat' left  and not actually filing on the rivet, it should be fine.



Scott at  Van's



 Looks like this is a typical problem.  Guess I will just trim a little  more.

  

 Thanks, everybody.
