Apparently nobody want's to make these because there's no money in them... http://cgi.ebay.com.au/w...gories%26_fvi%3D1&_rdc=1Oop's forgot to add the ebay item. Edited by user Monday, 7 March 2011 6:26:40 PM(UTC)

set up costs compared to how many people need them or would buy them is the factor, old ones can be repaired and rechromed.

Maybe Cloudy, but I would like to see how pitted ones are repaired. Even repaired you will still have the same crappy base metal under the chrome.
Yeah agreed, price and market demand is a big factor, but surely in this day & age of computerised machining techniques making them out of billet would not be too far a stretch.

Why make them out of a billet? Why not make them out of ABS plastic and chrome them, just like the washer nozzle on the bonnet?
You would never know until you tapped it with a metal object that it was plastic.
They would never pit and the price would be very reasonable.

it all comes down to price
i've been asked to make these a few times, so why haven't i made them?
well they can't be made in a sand mould, there too thin
so you have investment cast (lost wax)
or die cast
both them options are VERY expensive tooling wise (think in the 10's of thousands)
unit price would be quite cheap, but you'd have to sell alot for alot to just make back your tooling costs

I'd like to know how the "pitting" is repaired before they can be rechromed. Can anyone explain this?

I think they copper plate them and buff them before chroming. Or something like that. |

I would think after de-chroming they would be subjected to linishing some form of brazing perhaps to fill holes and re-chrome, expensive exercise. Zork restorations in SA do this type of work.

I do not see a problem with parts being made that suit, no matter what they are made of.
There will be those that want the genuine part and others that just want a part. Remember all after market parts are not built the same as the originals, and many can easily be detected. How many Hj to HZs are running around with Tiawanese fronts? They are made of a slightly different metal and do not quite allign, but 99% of the owners of these cars would not care.
No one would complain about fibreglass guards being fitted to an HK so why tail lights?
BTW the process for fixing the metal that the tail lights, mirror arms, door frame etc is very difficult.

yeah pretty much first the chrome is removed, then the pitting is sanded back, the holes and low spots are then filled with solder a GOOD plater will then copper plate, then nickel plate THEN chrome plate most platers these days skip the copper process due to the extremely strict EPA laws and associated dramas ALL non ferrous metal is difficult to plate (unless it's a copper based metal) and WILL NOT last forever, at some stage it will oxidise under the surface and cause pitting the lens frames are die cast in a zinc based alloy, it's the oxidising zinc that causes the pitting, the car manufactures use this metal cause it has a low melting point and is very easy to cast

Partially. It is also particularly good at retaining detail and small tolerances, hence its use in such things as lock barrels and carburretor bodies.

thanks for adding to my post carltonIV, i wasn't aware that there is 2 different types of the copper process, you learn something everyday also i like your post about the metal, i diecast aluminium as part of my job, thanks for your info

Greetings, If the ABS plastic part was dimensionally identical to an original, then that would be ultimate manner to remake them. I for one would like to see an HK with pin sharp rear light frames instead of the sorry examples you normally see that have supposedly been restored by some magical process. BTW, ABS plastic was used in HT and on grilles and there are no problems with pitting or blistering on those bits. Can't say I've seen a schmick 48 or FJ grille for a long time. |
look out, the guru is coming through... |

ABS would be far too weak for the "fins", they would break as soon as look at them. The zinc casting alloy (eg ZAMAK) has a tensile strength around 280 MPa, ABS around 50 MPa. Youngs Modulus about 130 GPa for the zinc vs 3 GPa for the plastic. etc. ABS would just snap.

Geez, plastic HK tailight frames. Its hard enough to bring myself to put inferior taiwanese reproduction items on a HK HT HG now but I'll be damned if I'll ever put plastic tailights on one. Whats this world coming to? I'm in the business of dismantling these cars every day and I work on high end Monaro restorations too. I prefer to spend hours putting life back into a genuine part and its components than opening a packet with a new 'alternative' in it and fitting it. I can tell you which one fits better and is more rewarding. I dont believe for a minute that we would have to resort to plastic tailights when there are plenty about and given to the right chromer/plater that knows the process, they can be adequately repaired. This is the key. There are chromers and there are chromers. Edited by user Saturday, 12 March 2011 5:25:54 AM(UTC)

What's this debate about. Back to the $s of course. The quality of the replating job will depend on the $s you're prepared to pay to get it job done. It's been getting done for years. Good and bad.

Hi Guys, looks like not many of you on here were at the Monaro Natonals.I had the first raw samples of these on display there.We have trial fitted them & were doing a bit of fine tuning to perfect them before they go to manufacture. I'm waiting on the next set of samples to trial fit in our old school panel shop.Once approved stock will only be a matter of weeks away. Not sure on exact pricing yet,but it will be realistic. The more orders we get for the first batch,the cheaper it will be for everyone,so if need these, register your interest by emailing us- [email protected] i will also send you a list of all other new parts made or being made,or give us a call on - (07)55490351, cheers, Paul.
