I mounted the dash with dzus fasteners, test fit my guages and am in the process of fabbing up a driver's dash extention for the tach and turbo pressure. I am trying to get all the aluminum in the car finished so I can send it down the road to the annodizers. Once I recieve the flocking material from the UK I should be all set with the dash.
Coolant lines and radiator mounting are next, suspension is ongoing. Some pics of the dash installed. |

Fuck everyone. That's cool as shit. I hate how everyone wants carbon fibre to be perfect and uniform weave pattern with no overlap, etc etc...
LAME! Look at an F1 car chassis before they paint it. Or the monocoque when the bodywork is removed. Its the same thing, nothing is meant to LOOK good, its meant to work, be strong, and be light. Kick ass. Yea coat the top so that the glare from the resin won't blind you. And it's super baller that you used Epoxy resin. How many layers? Just 1 layer and epoxy resin? Awesome true motorsports right there! |

fyi unless you have something between the aluminum and carbon fiber like a rubber gasket or fiberglass the aluminum will eventually be eaten away due to galvanic reaction, because the carbon fiber is a cathode (+) and the aluminum is a anode (-). the only thing that will be left is the stainless steel rivets

Bill,
The dash looks great. Did you set the fasteners or grommets for the fasteners directly in the resin or are they seperate? Nice work on the mold. Cheers, William

I didn't know about the reaction between carbon and aluminum. Will the resin be enough to seperate them? The aluminum will be annodized, does that make a difference? Thanks for the heads up.

Sean,
The VDO guages will be extended out from the stock dash location. I'll post some photos when it is all done. William The fasteners are riveted through the dash and into aluminum plates underneath to distribute the load (may re-think that one thanks to Sharkeyes) |

Great job Bill, if I get out of work early this week I'll stop by and get a close up look of it if that's cool.

As far as i know, no, the epoxy is not enough to keep the carbon from reacting with the aluminum. i use either a home made rubber gasket or a thick coat of primer and sealer. as for annodizing i dont think that will change anything because it will still be negitavly charged, and annodization process does not actually "coat" the metal. im no expert just a do-it-yourselfer so if anyone else has any info please correct me.

well, anodizing is basically dying the surface of aluminum oxide by placing the part in a charged acid bath.
the dye is trapped in "pores" in the metals surface. the whole "coating" process creates an oxide layer just a few thousandths of an inch thick (depends on process used) while i don't know anything about a galvanic reaction, i'd put money on anodization not stopping it

Looks nice. I was talking with my alloy honeycomb supplier today about "galvanic corrosion". I seriously would not worry too much about it. A structural part is another story. I am addressing corrossion issues on my parts since we use alluminum honeycomb as a core material. There is a supplier that i use for very advanced fasteners you might take a look at for future projects. Their adhesive bonded studs are used on my production sunroof replacements and some newer things i am working on at the moment. But they address this issue using a 2 part adhesive. The stud plates range from Titanium to carbon fiber. And they range in use from snow boards to the Predator UAV Aircraft. Click Bond

Thanks for the kind words everyone. Its very encouraging!
The dash is more or less finished but I clumsily dropped my vdo tach (and the glass shattered) that has some history in a few of my cars so that was a let down. On the bright side, I found a used 80mm Stack ST200 Tach in Belgium for ~160$ so that is on its way. So, behind the wheel in the shroud will sit an 80mm tach and 80mm turbo pressure guage. I worked on modifying the front control arms last night and tonight. I added threaded inserts to the inner side for a 5/8-1/2" rod end, strengthened them inside and outside. The outside balljoint was replaced with a 5/8 monoball assembly and strengthened, alot. If someone trys to break into the shop, I'm gonna beat them with this thing! Tabs for the tension rod and bladed sway bar links have to be added but I'll wait til they are on the car. The remaining rear arms have been modified for rod ends. I was going to make tubular ones but I really have to get the cooling system/wiring done so time is tight. The rear subframe is lightened by 9 lbs. I bought these sweet subframe bushings from Ian at SPL Parts and they arrived in 3 days. They are the first 240sx parts I have bought new and are well worth the 120 odd dollars that they cost. I was going to have the machinest next door make them but for how well priced SPL's are, I couldn't pass it up. |
