JDM Style Tail Lights

Recommended Posts

Hi,

I've been looking into making my own tails lights,

I know that they come up once in a while on Yahoo, but to be honest I can't be bothered, so I'm making my own.

Since I have not done molds before, I've started small.

I just poured the other half of the mold, so tomorrow I will know how it turned out.

Hi,

This is what I found this morning,

I think it turned out pretty good.

Tonight, if I have time, I'll test this with my clear resin.

What did you use for resin? How did you go about making molds? How did you locate the correct colors? Details please, very interesting. I had considered a similar effort to make me a set of JDM 240z taillights.

Thanks, Charles

The part I'm making (above) will be clear ( reverse light ),

the other parts will be 'tinted red' for the brake light.

I'll be using this dye

http://www.barnes.com.au/catalog/product_info.php?cPath=73_78&products_id=1567

this is the clear product

http://www.barnes.com.au/catalog/product_info.php?cPath=90_94&products_id=1455

I'm not 100 percent sure how it will turn out, but I will see, also I'm not sure how the resin is going to handle the uv.

this exercise is not cheap once you add the costs together, but at the end of the day, I will have molds to make lots of copies, maybe there will be a small market to sell them.

atm I have spent a good $350ish

this includes a pressure pot, vacuum chamber and vacuum pump, mold martial, clear resin, dye, and other bits and pieces. the mold martial for the above mold cost $75ish by itself, but it was the 'good' stuff and should last forever, or till I'm dead.. :-)

these 2 pictures show the Aus delivered lights ( red centered brake light), against the JDM tail lights (red outer brake light )

wow, thats awesome! Hope it works for you. A lot of people miss the fact that the outer red/orange light on OZ/NZ ones is actually raised. Im lucky I have sets of both, I'm sure I will cry if my JDM set was to get damaged! Can't wait to see your final result.

Nigel,

Are you currently molding the interior lens? Will you make the exterior lens in another mold and combine the 2 pieces? How would you mold a 240z taillight where the colors all meet in nice straight lines? Do you mold 2 of the 3 pieces and then put the 2 completed pieces in the last mold and let the third part bond to the first 2 while in the pressure pot?

The 240K tails lights come apart, so I'll mold each piece separate, and screw then together, just like the oem parts.

To be honest I have no idea how the 'Z' lights are setup, maybe you could make the separate colours, then join them with a clear over the top as you said.

Hi,

I had some more free time and decided to test this with clear resin this afternoon.

When I finished, I could swear I smelt this stuff before, after 20 minutes or so it clicked, same smell as bog.

I will wait and see how it turns out tomorrow

Lesson for today,

make sure the resin is %100 set before de-molding,

and putting the mold back together, and warming it in the oven for 40 minutes does not fix the issue of stuffing it up...

Looks ok looking at it on my phone? What aren't you happy with?

It hasn't got a good smooth finish, I don't think I'm leaving it long enough to set, or not putting enough MEKP catalyst in it.

It's cold where I'm working on it ( about 10C ), the next one I'll put it in the oven for 30 -50 minute before I open it.

just to make sure we are talking about the same part, it's the clear center lens ( will be the reverse light )

Hi,

I'm getting a nice collection now,

but I not getting the results I want,

so I sent a email to the company that I been buying my stuff from, and it appears I'm using the wrong type of resin,

hopefully in the next week my order of "BJB rigid waterclear" will turn up.

Thanks you for the encouragement.

Hopefully they will turn out good, if they do, I'll sell a few of them, I don't see a big market for them,

but since I need the mould to do mine, I can do some extras, so it should help some others.

Nigel,

how easy do you think it would be to create a part from scratch using this method?

could you make a solid resin block, cut it in half then carve out the reverse of the mould?

Thinking towards the GT-R style outer rings, but i could also do with making a set of larger guage rings to fit the autometer guages i will be installing

post-6769-14150815246099_thumb.jpg

could you also post some more details on the equipment you used (vaccum setup etc.)

thanks

Kent,

If I was to make something like this, I would make the part out of wood / bog / hard foam / etc., then take a mould of that.

I was looking at making the square cornered reflector ( the one on the bumper bar ), but I don't know how to get the chrome finish, I assume these have a chrome finish on the out side ( It's a bit hard to see with your photos, and the ones I have I cant see it either)

When I get some more time, I'll take some photos of my gear for you.

This is my gear,

a $10 pressure cooker, a square 10 mm thick flexi glass (I was told it's the stuff they use in excavators to stop the trees getting the driver)

a vacuum pump, vacuum gauge,

this is the main gear I use, also I can pressurize the vessel if I need to.

also I wrote some code to work out the measurement of my resin, sine it's mixed 100 : 88 parts

I have made some progress into making the center light,

it turned out pretty good I think.

also started on one half of the mould for the inner tail / break light.
