hiya,

I'm trying to make my own fibreglass interior middle panel thingy, the radio stuff.

The idea is to use plaster to mould the interior panel from the inside, then do a reverse mould. and add some custom bits into the plaster.

Get fibreglass resin and voila..

the problem is, I have no idea how fibreglass works...I have seen those fibreglass pack thingy sold in bunning, do I get one of these and it'll work? or do i need like a seperate resin to stuck everything together?

I intend to make a sort of "sliding panel" to hide my head unit, so the fibreglass section have to be thin. From what I have read so far, I need to sand the fibreglass to get smooth surface. but if my fibreglass is thin, I think it'll crack the moment I sand it... can I just spray a really thick layer of primer making everything smooth?

How do i get the super glossy look the audio shops produce when painting the panels?

cheers

make the panel with 2-3 layers of fibreglass if you want it to be extra strong, mix up the resin itself and brush it over the finished product - then you can prime it up etc make it smooth & ready for painting.

the fibreglass repair kits they sell @ bunnings would be sufficient,

either that or look up your yellow pages and find a shop that sells firbeglassing and moulding stuff, they will be able to help you out with supplying a proper fine weave glass (the bunnings kit's I have seen are only chopmat). Using a fine weave glass over chopmat will give you a better result with 'sharper edges' especially as it's only a small component.

To make the mould don't worry about making the inside mould just make the reverse one with the insert to begin with, polish the insert up with some floor polish so that it doesn't stick to the plaster mould. Then when laying the glass polish the inside of the mould with the same stuff so the resin doesn't stick to it.

For best finnishing results either do a gelcoat layer (this is easy and you dun have to mess around with sanding and painting and shit) the gelcoat layer just gets painted in before you lay the glass. The way they get the really shinny finnish is they use a 2pac paint and gloss out of a gun. Because it's an interior panel just bog it up with carbog to smooth it out and get a good surface for painting.

The sliding panel is a bit beyond me though, if I was gonna do that I would just use a plastic piece and paint it the same and find some plastic U channel for it to slide on and use some glass and resin to fix it into the back of the insert, as for keeping it open perhaps a small magnet or something.....

Heres my custom dash, is this what you mean?

I cut out a piece of arcylic to suit with a jig made for my router, then glasses it in from behind. Unless your good with a router I would nt reccomend it.

I used to design and build fibreglass body kits. If you need help on mould making and replication using gelcoat and fibreglass i will be happy to help. Its tricky if youve never done it b4 but once you know how its all pretty much the same technique.

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
