Hi Curt, Check out this attached picture of my firewall construction.  There really is no gap after all the rivets are in.

David,  

   

I see the ten A5 rivets in 7F8-4, then it looks like there are four more A4 rivets, then a gap, and then the two rows of A4 rivets continue.  Doesn’t that area behind 7F8-4 (between the ten A5’s and the four A4’s cause a bend in the stiffener (7F8-1)  (looking from the side)?  I assume that the rivet gap is because you have not put in 7C4-2 (Pedal Central Bearing) yet?  

   

Curt  

   

p.s.  It was good to meet you the other day to talk CH701s.  The water jet cutter ripped my 0.75”x4”x96” AL bar down to 3.25” wide like it was butter.  The Landing gear is bent and ready to go on the plane.

The top of drawing 7F8 shows the lower bearing plate (7F8-4) on the outside of the skin (like your second picture).  

   

I’m wondering about a wedge made out of 0.090” to the rear of 7F8-4 so that the stiffener transitions rather than having 7F8-4 being punched?

Not sure which is correct but it can be built either of two ways. The first shot (white paint) is of my unflown 701. I didn’t build the section shown. The second shot is of George Race’s 701 N73EX (from his excellent DVD of photos). You either have a gap between the floor and the plate or between the plate and the channel. Unfortunately no one has a shot from the side to show what happens between the channel and the plate. The shots in the Zenith photo assembly guide from inside the fuselage don’t appear to shot the plate. So I guess it goes outside. I think I prefer it that way – like George’s and David’s. But it is worth asking Zenith about. Let us know what you find out.

Where does the Central Floor Stiffener (7F8-1) go in relation to the Front Lower Bearing Plate (7F8-4)?  Does 7F8-1 go below 7F8-2?  That is what drawing 7F10 seem to indicate.  Won't there be a gap between the floor (7F8-7) and 7F8-1 at the end of 7F8-4?

Oh, one more thing.  Aren’t the bolts on 7F8-4 in George’s picture too short?  BTW, on mine when I use AN3-10A (per plans) they seem too long.

I'm at this stage of building my 701 and I saw the same thing. Those 10's look really long. Anyone know the reason for this?

You could just file a ramp on the trailing edge of the plate. I don’t think you would have to take it down to a knife edge. I’d love to see a photo from the side with all the rivets and bolts in to see what happened to the channel.

I filed a bevel on mine as Craig suggested and this made for a nicer fit .

Hi Curt:

  

 Here is part of my picture, Nose Gear 2.jpg from the  DVD

  

 Note there is a very small tapered opening from the back of  the bearing plate.  Also note the longer "final" bolts in the bearing mount  with extra spacer.

  

 I am not sure what I am seeing in your picture.  Looks  like the floor pan is sort of bent up away from the mounting bracket below  it.  Maybe just an illusion the way the picture was taken.  I don't  see that same floor pan warp in my picture, but it is taken from a slightly  different direction.  Will keep looking to see if I have any better picture  of the area.

  

 George

BTW: Zenith “solved” this problem on the 601. The channel is wider than the plate. So the plate fits inside the U of the channel. I wonder what they do on the 750? Given the resemblance of the 750’s firewall to the 601 I be it uses the same approach.

Hi Curt:

  

 Here I think is a better picture from a slightly different  angle.

  

 Everything is riveted together on this  one.

That's what mine looks like. Right or wrong, I don't really see an alternative.

For those who still have access to the firewall, you might want to go ahead and put in whatever baffling you plan to use over the nose steering rods.  I waited until I had the engine on and the plane on wheels.  It was a pain to install.
