Broken Windshields?

Hey guys,
Does anyone know if you can fix a crack in your windshield, and still be legal? Or do I need to buy another? The thought of spending another 100 bucks is not that appealing right now!
Cheers Mac

 

where did it crack??? pics always pics give me some pics. let me see your craked windshield.

 

Well, seeing as how motorcycles don't usually come with them (except maybe the large cruiser Hondabago type models), I'm inclined to think that having a cracked windshield isn't that big of a deal. A car, yes, as it's a safety issue -- but not a bike.

 

duct tape!!!!!


If it moves and shouldn't...duct tape
If it doesn't move and should...WD40

 

I sprayed chrome paint on my gsxr windshield not sure if it will pass inspection but either way I couldn't see thru it being a original part off a 86.

Depends if its Plexiglas or Polycarbonate.

Acrylic Solvent:

Done properly, an acrylic solvent can be used to bond two pieces of acrylic such that the resulting piece is essentially a single seamless piece of acrylic. However, it is difficult to properly apply solvent to repair a crack as opposed to joining separate pieces of acrylic. In addition, acrylic solvent is really nasty stuff.
An easy to find brand of appropriate acrylic solvent is IPS Weld-on #3 or #4.

Epoxy:

There are many kinds of epoxy and many do not adhere well to acrylic, but epoxy that bonds acrylic is available in most hardware stores.
For best results apply the epoxy to both sides of the crack.
Unfortunately epoxies that form the strongest bonds with acrylic are not transparent, they're generally amber or off-white in color.
Easy to find brands are Devcon Plastic Welder or Loctite Plastic Epoxy.

Cyanoacrylate:

Colloquially called "super glue" or "instant adhesive", an appropriate cyanoacrylate will form a decent acrylic bond and most cyanoacrylate adhesives are transparent.
I'd probably apply it from above, allowing capillary action to draw it down into the crack. For acrylic, I'd recommend Loctite 401 Prism Instant Adhesive.

Ridout Plastics recommends the following procedure for repairing a crack in a piece of acrylic:

...cracks can be stopped with a simple procedure. Using a very small drill bit, 1/16" or so, drill a hole through the material at the end of the crack. That's it.
If it is a long crack, you might be able to inject some IPS WeldOn #3 (methylene chloride) into the crack to partially seal it.
You should glue a 1" strip of 3/16" Plexiglas to the back side to reinforce the cracked area.
