I've been playing with some carbon fibre again.
This time I made a cf version of the standard exhaust shield on Tiger 800.
Just sprayed, still needs a buff and polish. (2 weeks)
Heat resistant resin for cf is very expensive and it's difficult to achieve the temps to cure it properly. So I just used normal epoxy resin, thus I need a heat shield of some kind.
I shopped around locally and found an A5 sized sheet for R250. Expensive if you ask me, so I've hacked up a home made one for next to nothing.
First off I pinched some aluminium foil from the kitchen whilst the missus was on AWOL somewhere.
Fold it in half and roll it flat.
Next cut up some fiberglass mat sheet from the local hardware shop.
Lay the fiberglass onto the folded foil and cover it again, rolling flat.
Stencil and cut out the shape you need for the final shield.
Wrap it one more time, tucking it over the edges so it stays together.
Final shield, with depression and holes for mounting.
Testing the shield quality.
I took just the shield and made two balls of molding wax, one under the shield and one alongside - unprotected so-to-speak.
I set my heat gun on highest setting about 10 inches above the shield and nailed it for about ten minutes.
The unprotected ball of wax bubbled and smoked away, basically vaporizing.
The wax ball under the shield held it's shape and was still touchable.
I used some high heat resistant gasket sealer to 'stick' the shield to the cf. It's busy setting now.
Will it be enough to stop the cf resin from discolouring? Time will tell, but it does work as a shield.
