Hi Guys,

I'm getting ready to Bond the Windscreen in but I am worried about how to close a Gap that is between the Glare Shield and the Windscreen.



On the Starboard side it's worse than the Port side see the attached Photo.



cheers

Get it down as tight as you can, then fill the gap with flox and epoxy slurry mixed to a peanut butter consistency then immediately start your Lay-up.

You may also wish to mix a black pigment into the resin so the fabric doesn't stand out so much while viewing from inside the plane.

Good point, I used black epoxy dye in all the resin used around all the windows, including the flox.

On the narrow gap between the bottom of the windscreen and fuselage itself, fill with micro balloons.  This is not a structural issue.  Sand to make a nice fillet to overlay the cloth.

I used carbon fiber and standard West epoxy for the bottom windscreen fairing instead of fiberglass.  It looks nice from the inside and I find for applications such as this it is easier to work with.  Make sure you rough up the glass and fuselage bond areas with 30 or so grit paper.  I used   a bunch of cheap Harbor Freight black electrical tape to mask off the glass and fuselage.  A couple of layers and it provides a nice sanding shield for your finish micro balloon sanding.

I also started with a large gap such as you have.  I was able to narrow it down a bit by some additional sanding at the front.  I still ended up with an 1/8 on the right side.  I mixed up a peanut butter consistency of West 404 and 105 epoxy structural filler to fill the gap.  The issue you have with leaving the gap is when you finish the side for paint, you will end up with a bulge.  Be sure to paint the area directly under the window with whatever color you are going to end up with on the dash, it is easy to do prior and hard to do after.  If you are going to use textile on the dash, paint the color of the material around the edges where the plexi meets the metal.  You might also consider painting a mask on the INSIDE of the plexi around the entire perimeter.  This will hide any gaps or bad areas of glass seen from the inside.  Also be sure you add black dye to the epoxy.  You can obtain this from West Marine.

I went with a metal fairing instead. Got it from M.L. Skunk Works. Here is his site:

I thought I read somewhere that you should not use carbon fiber cloth in direct contact with aluminum because it promotes corrosion.  Not sure if this is a tale or based in fact - but probably worth further research.

It is a fact.  The material has both advantages and clear disadvantages.  Fasteners are usually the first to fail.   

Search out the " Nobility" table of materials.

The different conductivity of aluminum vs. carbon is increased by using the aluminum as the aircraft voltage ground return path.  The carbon can retain moisture.  Adhesives of carbon to aluminum and carbon to other fibers set off the difference - Nobility Table.  One technique is a cloth boundary between the two dissimilar materials.  Then all the electron flow is through the fasteners.  Carbon, Kevlar, combinations bring a higher level of sophistication that "Good old E glass or S glass" against aluminum alclad.

  

Research the FAA AC pubs on Inspection Techniques for various forms of corrosion.  Research builders of plastic aircraft for the challenges such as the carbon cub, Lancair Evolution, Legacy or comparable builds.  All decisions carry risk.  Weigh them and fly safe.

True, but if the carbon is encased in epoxy, there shouldn't be an issue.

It's the same reason you should never use a pencil for marking aluminum.

Thank you everyone for your replies.

I have applied two layers of Glass and then  built up the side of the Glare shield so that the gap is only around 1/8 ".



I will be using Sikaflex 295 UV and then the Glass layup as per the plans.



cheers
