[How to] Create a custom mount for an HKS EVC 3

Postby Dups90gt » Sun Jan 18, 2009 2:06 pm

Here's a how to to create your own custom mount for any boost controller, this is just a guide for an EVC 3 but the shape can be anything anywhere on your car.

oh no another picture filled project by Fernando!

So I received my HKS Boost Controller and was looking for a place to mount it. I wanted it to look stock or as close to stock as possible. I was thinking of mounting it in the spare radio compartment but then thought what if I get a double din stereo later on.. then the cup holder, I could install my boost controller and my turbo timer there but I don't think I could live without my cup holders.. so there's the ash tray, humm I would have to close it off and make a mount and a hole for the controller but It looked like a good spot.

Its freezing out and I don't have a garage so I had to work with what I had. short strand fiber, first I removed the housing and unscrewed the ashtray mount.

found some plastic from an old box of clips and cut it to cover the hole. User plastic as fiberglass does not stick to plastic and it will be smooth.

Here is my small table and the bezel and the plastic and a pair of scissors a blade, tape (ok so I didnt have masking tape but had a lot of Christmas wrapping tape..so I used that) Newspaper tin foil and a marker.

Image

Cut the plastic to cover the ashtray hole.

Image

Test fit it so it covers the entire hole.

Image

cut a hole out for the controller
Image

Tape it onto the bezel (try and use masking tape.. much better, only plus is that fiberglass does not stick to it at all)
Image

wrap you controller in foil and tape it up, we need to make a perfect mold for the controller so we dont have to make a mount.
Image

Image

get a piece of dense foam and cut out a section for the controller , we will use this to press down on the mold.
Image

Pop open your glass.
Image
Image

Oh shit dont forget to cover your work area .
Image

Test fit it on the foam.
Image
Image

Take a 'Jackie Chan' Book and flip enough pages to balance the rear of the bezel.
Image

Grab a plastic container (You can use the lid but I needed it to pour in later.
Image
Scoop some glass into the container,
Image
add hardener
Image

mixed, the more hardener the faster it will harden, I put alot coz it smells so bad and Im inside the house. (wife not home yet)
Image

I put the controller wrapped in foil in the mold and then poured in the glass mixture, let it dry for a bit (3 min) then pulled out the controller but left the foil (glass gets hot as it dries and I didnt want the controller to melt), and please no one hack on me for using the Bible to weigh it down, it was the heaviest book in the house.
Image

pour it in and push the stick up and down as you pour to get rid of bubbles, make sure you get it all in the corners.
Image

Weigh it all down while it dries (approx 40 mins)
Image


wait....
wait........
wait............

3 spongebob episodes later..

time to test the hardness... solid as a rock but still soft enough to shape a little
Image

Flip it over WOW HOW SMOOTH, the trick of plastic on glass..
Image
Peel off the plastic and tape
Image

See smooth..
Image

Peel off the foil mold and cut off the excess glass (careful its sharp)
Image
OK test fit the controller - PERFECT FIT, it even clicks in place.
Image
Image
Image

Time to sand it down and make it real smooth. wet sand it under a sing with 800 grit water proof sand paper.
here it is so far.
Image
Image
Image
Image
I added another layer around the hole as it looks terrible, Ill sand it again and paint it tomorrow as I dont have paint.

Image
Image
TO BE CONTINUED TOMORROW.

total time to build 2hrs 42mins.

ok so her we go.

After sanding down the 2nd glass coating its time to test fit again, look how crappy the opening looks, not to stock looking.
Image
Image

time to get out the bondo and fill in the gaps .
first pull out the controller and tape it up, tape the edges you want as the size of the opening so it sticks out.
then put it back in and mix your mud, I only used a tiny bit of hardener coz I need more time to work with the mud.
Image

here it is taped with a layer of mud on it.
Image
cut along the edges of where you want the controller to stick out with a blade then remove the controller. Here it is sanded down.
Image
now fix the hole where the controller will go with sand paper, be careful to to sand down too much! and keep test fitting.
Image

Now we have the shape but bondo is not smooth even if sanded with high grit sand paper, you need to use glaze putty on it.
Image
squeeze out some putty on a spatula and spread it on the pits and scrapes left behind by the sand paper.
spread it thin! it will crack if you spread it thick! bondo is spread thick, putty is thin.
Image
after wet sanding it in the sink and getting it smooth, I brought it to the stairwell to paint (hehe) flat black, if you want semi gloss get gloss and spray it when its freezing outside, it will turn whitish then go semi gloss later.
Image
Image
Image

after drying I test fit it in....
Image
PERFECT FIT!
Image
Image
Image
so what did I learn from this?

..............that I'm TOTALLY AWESOME!! Image

Total time from start to finish.
approx. 6 hours all in my condo. would have been faster if I had a garage.

sorry for the really late reply, i haven't been here much and just pop in from time to time. Total cost of materials was roughly approx less then $50. I had most of the materials at home from previous projects. When you buy glaze putty, dont buy the junk in tubes like I did. Get the stuff that you have to mix... so much better and spreads much better and is easier to sand. Its called flowable glaze putty and its green with blue hardener. looks like a soft short bottle with a springgy thing on top to pump out the glaze. ill take pics if I have time later.
