Drilling Carbon Fiber - what should I know?
�
�
I've done the research and decided that my new VIS Racing hood should probably have hood pins (hood locks, actually) since I see a lot of highway driving.
Is there anything I need to know before I drill this hood? Any special procedures, techniques, or things to look out for when drilling the CF?
Thanks.

Place tape on both the top and bottom of the area you want to drill. This will help the CF from splintering around the hole.
Carefully drill the hole thru the bottom of the hood UP by gradually starting with smaller bits and working your way up to the overall size of the hood pin +1mm of clearance around. Its ok if you drill a little bigger, if you'll be installing the silver kickplates so the pin itself won't scratch the hood.
install the pins and adjust the height so that the pins create gentle pressure down on the hood.
thats all there is to it.

Much appreciated!

And AVOID all contact with CF dust. Inhaling it is VERY bad and it's highly carcinogenic.:mad:

That's good info. I'll pick up a mask or 2. Thanks!

Why do you drill up..? It seems like you would want to drill down. I am also lookiung for advice about to install pins on my Seibon tommrow! Thanks guys

I would do the tape thing but if you have a step bit I would use that. If your drilling a pretty big hole a step bit makes a very clean hole.

put a block of wood to drill into.

carbon fiber will dull blades and drill bits VERY quickly so what you need if you are going to drill more than one hole is a carbide bit or even a diamond carbide bit.

not necessarily....it is the resin that is carcinogenic and there are thousand upon thousands of different resins.

ahh...well let's hope they used the 'good stuff' ;)

its all about going slwo and starting with a very small drill bit and working up. i did this on my old carbon hood and it worked very well. do tape top and bottom of your drilling location and it wont splinter at all as long as you are slow about it. get the hole a bit larger than the pin being used and i recommend a dremel to clean up the edges when youre done.

DO NOT touch the CF Splinters. They are a NIGHTMARE to get out. (Dont ask...just follow the advice)
| gotboost02 | 04-04-2007 04:52 PM |
yes the carbon dust is very bad for you ... and the splinters are just as bad ... i work with advanced composites daily, +1 on the block of wood ... wont be perfect but will be good enough

I always use tape when I have to drill and it works all the time :)

how are you marking on the bottom of the hood where to drill? i have an idea but im not sure if its the best way to do it...
| wacerx | 04-04-2007 09:02 PM |
make a small square of tape. stick it on the tip of the hood post. set the hood down onto it and it should leave the small square on the udnerside of the hood.
i cut a square of about 1" by 1" on the inside of the hood for the post to pass through. then i used my method of marking the hood so it was on the underside of the carbon and drilled a tiny pilot hole before drilling out from the top.

I usually put lipstick (DONT STEAL YOUR GIRLFRIEND'S!) on the post you screw into the core support, close the hood on it, and drill from the bottom up with a tiny bit. Then working from the top, enlarge the hole and shift the hole if needed.

CF splinters are a lot like fiberglass splinters, if you get any wash your hands in as hot of water that you can stand with some mild detergent, it helps open up the pores, wipe on a paper towel or something disposable.

I honestly don't think hoodpins are necessary. If your hood utilizes the OEM latch then it should be fine. I've had mine on a month and ran as high as 140 km and no problems at all. No flex/bend/shake it stays on like it should.. It's really personal preference I think, seeing as how I've read some of the horror stories of peoples hoods flying up and smashing their windshields.
But good luck to you !

Use stepped drill bits designed for sheet metal. They are cone shaped and gradually increase in size starting at about 1/8 inch. I used these with my hood pin install and they where gentle on the carbon fiber as long as you go slow.

I would get pins.. especially if you are running an STi scoop. I have taken many rides is a friends wrx with an Sti scoop and you should see the flex that hood gets at anything over 60mph! even on the al. hood, which is stronger!
the hood looks like this ----> ~~~~~ :eek:

i have a drilled hood i used on my 05 with an sti scoop. all this talk of flexing is very true which is why i took the time to drill that hood. unfortunately the hood and pins dont fit my current car so anyone who doesnt want to drill PM me.
i also rec. the sparco pins since they worked very well for me.
