Well as ur gona find out soon enough, when things are'nt as simple as flat panels and u have tight corners to get around the fibres dont always wanna play ball n stay where they should. So after u finish laminating ur part you then put on a release film, then some breather (which basically spreads the suction around ur part and absorbs excess resin too) and then bag it. So what u end up with is the better part of 1 Bar of pressure all over ur part. For a flat panel what id do is have another flat surface that is waxed to put on top (make a sandwich of the laminate) and then add some weight on it, this basically gives u a thinner better consolidated laminate. The vacuum bagging method is great but it also means buying the extra's that go with it. (Release Film, Breather, etc)

Clearly money well spent if u wanna make trick bits. All the best !!! Make sure u use gloves n have some acetone handy to wipe up the spills.

cheers for the run through..

have you got any ideas on what materials are the best to use as a mold creator of complex items...

basically i was watching monster garage. they had a foam type composite that the guy cut up using a saw .. was light but hard, then he covered it in fibreglass to make the item.

i want something that i can manipulate then take the mold off that in fibreglass so you can produce the item..

does that make sense?

well in ur case if ur only makin some one off bits for a play around then you can use high density foam/ MDF/ wood but ur surface will have to be either painted n polished in the case of the MDF/wood or sealed in the case of the foam. The high density foam also disolves in acetone so be careful there.

This process will form whats known as a pattern and from this pattern u get ur mould and then off ur mould u get a part... to be really cheap n simple id go with the MDF, u also have patten forming clay... Look im sure there is alot more stuff out there that i dont know off, but to start with these are very do able options. Maksure ur mould is thick and rigid, use a lot of chopped strand matt to bulk it up....

yeah i think i saw that clay stuff at the fibreglass suppliers.. looks just like play dough...

do you need to seal that? or does the resin just not stick to it?

think i read somewhere last year that it will not stick to play dough .. might be the same for the clay.. cos it re-usable from what i read on the packet

welcome to the world of carbon, i'm willing to answer any questons people may have. I'm actually a composite technician and work with it everyday. i work at custom carbon here in brissy good ol vacuum bagging least you guys are on the right path... beware stuff ups are a plenty in the world of carbon. Good luck

yeah the website has been down for a while, the boss is getting it all redone

i been on his case about it, guess its done when its done.

what R33 stuff you want pics of? for R33 the moulds we have are

Modified blitz 400r full kit

GTSt bonnet series 1

GTR bonnet series 2

GTR front grill

GTR lower lip

Bootlid that sits flush with rear panels

pillar mount gauge holder

GTR wing just the blade

door sil panels

I'm pretty sure thats it i'll get onto the computer at work tomorrow and get some pics. and post them up whan i can.

Oh and craved you still have to wax mouding clay/ play dough or plasters or the resins will stick to them.

are your products carbon overlays or pure carbon ?

Does anyone fabricate carbon front gaurds for R33 gtst's?

There is a magazine called performance build up's which has released a few articles on working with carbon/kevlar. That may help answer a few questions people have.

i found a company in japan that does them, but they were really expensive...around 2k each from memory

Yes, 2k is out of most peoples budget for gtst upgrades.Is the company called Bee-R?

I also heard somewhere about someone in SA that fabricates gaurds. Not sure if they are carbon or fibreglass. Have you heard of of anything along these lines?

      Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.

      Does the scanner do all the CUs in the car, or only the ECU?

      R34 N/a And R34 Turbo (gtt) Transmission.. Uh, Problem.

      By albyz34gt · Posted

      @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man

      Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?

      ECU sees many times the speed than speedo does (R34 swap)

      By GTSBoy · Posted

      Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
