Hello Phil

Would you be happy to add to your model collect the last one ?;)
I should be able to "masteryse" the plug based on one standard shell and then mold on silicone mold
Will make your collect UNIQUE !!!!

Hi Michel

Glad you are home safe !... also enjoyed the meal with you and Andy at the Piano Restaurant !!....

I did call in to see you last Friday to say goodbye ...but you would rather be at McLaren than have a visit from me !! LOL

YES.. the last model would be fantastic to add to my collection..... an F1 Strato's !!.. that would be a unique model

Thank you

Phil

Hello Phil
Yes !!! at the Piano was really fatastic food and chat !!! :cool:
Friday with Craig was a really interesting visit ; that Maclaren gt F1 is really a beauty
If you can find a standard kit next time you give me the shell and cahssis and I will do for you the master ... no worrie at all
will not be an Arena quality plug but arather very accurate model you can show in your cabinet !!!

Hi Michel,

I'm considering casting the Fiat Dino window knobs in black resin, or polyurethane.
I just wondered if you, or anyone else on here has any experience of making moulds for small car parts?
I'm guessing a silicone mould would be the way to go?

ABL Stevens at Sandbach will make moulds for you if you ask nicely, and reasonable charges.
They also give good practical tips like using a syringe to "de-gas" small quantities of resin so you don't have to shell out on vacuum equipment.
In addition if you really want to have a go yourself there are guides on mould making and casting on their website.

Thanks John,

There's a Word doc. guide to making something similar on their website. I've downloaded it.

Chris ; there is absolutly no problem for me to mould in silicon your parts; I did more than 500 different molds for model during 30 years and molding at 1/43 scale even wheel nuts or wipers !!!
When am in France at house ...have sometime left to help you friendly on that :o
The only issue for with window knobs or watever part to use on our cars is that black ( or noncoloured ) plyurethane resin is not enought stiff to support torsion or small loads on effort ; before to think to do those in resin and spend money in silicone it's advisable to ask to suppliers if they have resin able to afford this use ( On models we had F28 and F31 from AXXON and I don't know any other brand or quality )

I would think Epoxy would be the one to use.
I would think you could recover costs quite quickly through selling a good replica part on to the latest batch of builders. Maybe even a small profit!
You have to be really picky on selecting your pattern part because the silicone mould will pick up every imperfection.

Maybe speak to Mick Worrall with regard to the type of plastic to use and what sort of mould.

Yes you are right John
But you cannot cast only epoxy resin ; you need to add any sort of powder ( alu or watever additive ) plus black pigment and then know what is the right silicone to sue in order this mix will cure

I think honestly that the best way to remanufacture those parts is from "POM" ( black I sued to have the dimmer ring machined ) and have the part CNC machined
I have close to me specialists workshop in machining this stuff and seems ( after 2 sort of parts done successfully for Strats ) that they are reasonable in prices

john

Well if CNC technology is available at reasonable cost then that is the way to go
I would guess a FIAT window knob mould would cost about 75 from ABL and material costs for each part would not be more than a fiver.
It's down to how many would be a reasonable minimum quantity to get the price down with the CNC route.

Thanks Michel, John D, John H.,

Considering all your advice, I think Michel's 'POM' would be the best way. Those pull switch knobs and rheostat rings that Michel had made looked spot on.

I'm only asking because I now have two original Fiat Dino Coupe full diameter (front) black window knobs, but with a spare pair of the chrome wingnuts.
The spare wingnuts need somewhere to live. I think making just one cloned pair of the black plastic parts isn't going to be possible.

Production of the black plastic parts would also need production of the chrome parts. I really don't think there are enough Stratos rep. builders/owners who care enough about this level of authenticity, to make it viable.

LM mic

Those chrome wingnuts could be done with "lost wax process" but when asking to the people who did that for me years ago ; they do not accept more to cast wax on silicone mold done outside ! they ask to do their own molds and this is the issue as cost of this mold is far away from what we can afford ( in fact they do 2 molds !! one to copy and then when 10or 20 are cast they do the final multicast mold ... so pricy process!!!)
This why at to day I stoped working on possible remanufacturing those parts ( beside the fact since one year am ivolved alittle on my chassis !:o )

They'd still need a machine process also? Logical just to machine from aluminum in one go. I don't think there is a cheap way of doing them, for the amount of buyers, you could keep up with finding original parts.
Last time I talked to Mick regarding an injection mould tool, he said cost would be many times more than what the cost of the whole production run would be.

Yes, Fiat Dino Coupe values have risen, so there are far less cars being broken for parts. However, there seems to be a lack of demand among Stratos rep. owners for the rarer bits and pieces. So that's fine.

In any case, Michel has now solved my problem of me having spare chrome parts!
