| Subject: | Carbon Kitfox Crafters |
If you have seen some of my other posts you know I am trying to learn a thing or
two about composites and how to use them. So here is one thing I wanted to
attempt, carbon fiber coating an existing part. The unfortunate thing is that
you end up with the original part plus the weight of the carbon and the resin
but it should look really good when complete and it is pretty simple to do.
So here is what one of the McBeans gas cap fairings looks like coated in 2x2 twill
3k carbon. It is still raw and will look better once the resin is applied
and sanded (3 thin coats). It was applied by using black gel coat as the adhesive
which fills in any gaps with black. So far it has been fun to do and I
will be applying the resin here shortly so maybe that will change. Just thought
some of you might like the look. By the way, I may or may not use that part,
I am still playing with options.

Have you tried to switch the leads on the back of the gauge
to see if the low reading goes to the other on needle?

I'm guessing what you want is a carbon "looking" part as an end result.
Not sure what parts you'd do that for on a Kitfox, but it might be fun.
Now the normal process would be to take the KLLC part and stick it to a
piece of melamine and then lay-up a female tool out of gel-coat and
fiberglass. You'd then vacuum bag male carbon parts out of the tool.
This gives you a really nice finish on the outside, one that can be
lightly sanded and then clear-coated for a spectacular finish. The hard
part of doing it your way is getting a final product without bubbles.
It's really hard to get a "solid" layer of resin over weave, without
milkiness or bubbles. And you can't really keep a lot of resin in a male
part because the resin squeezes out the male corners and pools in the
female corners. One thing you might try is to put your part in a vacuum
chamber after laying on a coat or resin. This will help force out any
trapped air. Good luck!
