I'm stuck for a bit on the wings waiting for parts  and have started installing a new windshield. I removed all the fabric from one  butt rib and I noticed that there is no reinforment strip to catch the rivets  from the skylight. I can find no reference to one in the build manual but placed  one anyway. I have no need to strip the butt rib on the other side but it is  also lacking this strip. Is it normally there or not?  I think I could  place one without removing the fabric.

  My manual calls for a reenforcement strip.  However the original builder did not install it.  Anyway, when I replaced the windshield I used SS screws with a nylon washer on top and a SS washer and nut on the underside of the butt rib.  It takes a little more time to install with screws, but I have not had any signs of the Lexan cracking as I have seen with rivets.  Since I was using washers I did not see the need for a reenforcement strip.

   

  If you use this method, be sure to drill holes in the Lexan a bit larger than the screws to take care of contraction and expansion from temperature changes.

   

  Hope this helps.

Dave G,



The manual for my Model 7 calls for a strip of aluminum bonded with structural 

adhesive on the inside edge of the upper capstrip on the buttrib. The 

fastners for the windscreen are supposed to go into the aluminum strip.



Sincerely,

I figured there should be one. I've installed one on the side I stripped. I 

guess I'll have a go at the other side. Thanks.

Dave and Jimmie,



2 seperate considerations here.  There are washers

made to be used on the inside of the rivets to keep

them from pulling thru the wood, if that is the only

consideration.  The glued in strip is just easier to

keep in place than trying to hold a washer while

pulling rivets, but the washer gives you and option.



Second, there should be a reinforcement between the

rib cap and the rib web.  This is so that the rib cap

glue does not let go with the strong lift created by

the windscreen.  That has happened a few times.



I made "L" shaped reinforcements that are glued and

riveted to the web, then drilled thru for the

windscreen bolts I used like Jimmie's, instead of

rivets.  I didn't reinforce every bolt, but maybe

every third.  For the other bolts I just used washers

like Jimmie did.

Here is more info from the windshield installation section of my

Series 7 manual:



The windshield (and skylight combo) uses AN526-832R10 machine

screws, AN364 shear nuts (the strength of 365 nuts is not required)

and plastic washers.  There are 5 on each "A" pillar, 8 on each butt

rib, and 10 on the skylight angle (the bracket that attaches to the

rear spar carry-through).   The windshield-glareshield interface

uses 6 AN526-1032R8 screws, AN364 shear nuts, and AN960-10 (metal)

washers.



You start the holes in the windshield/skylight with a 1/8" acrylic

bit and later enlarge them to 1/4" using a 1/4" acrylic bit.  The

holes in the fuselage are are started with a 1/8" metal bit.  The

holes in the "A" pillars and skylight angle are later enlarged to

#21 (0.159", slightly larger than 5/32 but smaller than 11/64). The

holes on the butt ribs are enlarged to #18 (0.1695" or slightly

smaller than 11/64").  I thought the #18 was a misprint and only

used #21 for all the fuselage holes.  The holes in the glareshield

are enlarged to 3/16".



The manual says to drill the holes (1/ in the fuselage first, 

then match-drill the windshield holes (1/.  I think that I chose

to drill the windshield first and match-drilled the fuselage, but I

honestly can't remember.  All I wrote in my log was "worked on

windshield."



Once all of the holes are made you enlarge them to the appropriate

size.

Notes on drill bits:



#21 bits are sometimes packaged together with a 1032 tap and 

available in some but not all hardware stores.



I've read that acrylic can be drilled using normal bits in reverse,

as these melt the plastic with the heat from friction.  I don't have

an opinion on this either way, I didn't try it because I had the

"most correct" tools for the job (1/8" and 1/4" acrylic bits).

Misc:



The aluminum backing strip is .020" thick 2024T3, 1/4" wide and

about 28" long.  This is bonded underneath the butt rib top capstrip

and reinforces it.  It is superior to using washers alone to back

the skylight attach screws.



Interestingly, the holes in the door windows end up 5/32" and the

quarter windows #21, but those windows are attached with 1/8"

aluminum pop rivets, not 832 screws.  They are also polycarbonate,

not acrylic, so they apparently (?) do not require special drill

bits.

Hope this all helps...

Series 7 in progress (just really slow progress!)

I installed 10-32 nutplates under the butt rib capstrips, using solid 

rivets to hold them in place. It makes life a lot easier when you 

install, and a whole lot easier if you have to replace, the 

windshield/skylight.

I like that idea, perhaps with a smaller nut plate, maybe a 6-32. It would 

be no problem with countersunk rivets on the butt rib. I could use regular 

nuts on the rear attachment.

keeping up....OH MAN, DID I SAY THAT?...am I gonna be sorry I said 

that!
