I have been exploring the option of 3D printing these in metalised simulated ABS . |
There have been a great many advances in the field of "rapid prototyping" lately and these processes (3D printing, high-definition stereolithography, rapid urethane casting, etc.) may be just the ticket to fill the need for low volume, high-quality plastic parts like these trim pieces. Parts can be made directly from 3D CAD models...no drawings required. A set of OEM trim pieces would need to be measured and then modeled in SolidWorks, ProEngineer or similar CAD system. These models can then be used to produce exact copies of the desired part. And unlike traditional molding, there's no tooling cost involved and it's not a problem to do only a small run of parts.
RPDG, Inc. is one company that specializes in this sort of thing. They'll even provide completely finished parts (painted, metalized, etc.) if you so desire.

A quote from their website:
"With a diverse range of rapid prototyping technologies and materials at our disposal, we can choose the best materials and process for your pre-production prototype or low-volume production parts and create precision, full-scale 3D models of virtually any shape, with the precision fit, finish, strength and material properties your application requires." _________________ '63 Ragtop (current)

So, I decided to try to make the piece between the gauges. I don’t have an original to make a mould, so I decide to make a piece from leftovers from my first test and using pictures here to try to guess the right size and shape. I also don’t have access to the Ghia dash right now, so this is totally “With Guesswork”. Apologies once again for the terrible cell pics.
Looking at the picture in this thread showing the backside of all the trim pieces, I measured the size on screen, averaged top and bottom to allow for the tilt, and came up with 20mm wide x 30mm long, scaled that up using the trim piece I had, it worked out to 33 x 49mm, but I may be off a bit (if someone has some of these handy, I’d much appreciate some exact lengths).
Anyway, I took my best guess at the curve, I’ll find out if I was close when i can get out to the ghia again.
Shaped most of it using some 150 emery paper taped to the radius of a roll of duct tape, then smoothed it out with 600. masking tape roll gave me consistant height for bevel on both ends.
Painted it with silver spray, taped the centre then sprayed the edges “chrome” (didn’t really need to paint this one though)
So, if this one is accurate, I’ll fit some pegs to the back and use it to once again make a mould, then I can cast this one as well...

So, I made my first attempt at casting a piece of dash trim in urathane from an original piece. It’s not bad for a first attempt, but I learned a lot, so I think the next one will be better. It really wasn't that hard to do. Sorry for the crappy cell pics.
I bought a 66 glovebox door from a Samba member, it had a piece of og dash trim still attached, but it was very fragile and had a few pieces missing from it.
I patched up the missing bits using playdoh, and made a two part cast of it from plaster, which is not the way to go, I’ve got some more appropriate material that I’ll use for the next one.
I put in some stainless screws at the last minute. ..not sure if this is the way to go yet.
Cool that it’s an exact copy, even some of the detail from the og like this number transferred (hard to see in the og).
Painted it up with silver spray , then taped the center and sprayed again with “chrome” spray. As I said, not perfect yet, but not bad for a first time.
I think I’ll cut this piece up, and try to make the other four pieces using photos from here, I can trial fit them to my dash.
Once I’ve got the mould made I’ll be able to make a bunch of these.

Hey, I thought it was a pretty good idea. They were originally plastic after all, and I have seen plastic parts made from silicone moulds.
Advantage of using moulds rather than milling them, is you get an exact copy of the original part, and i'd say it would be cheaper and probably easier to do.
Just sayin’ it is worth a shot… you know being inventive and improvising, much like the original owners of our cars used to do… nothing wrong with that. |

Hi Bob,
I have a full set LHD but I'm in Australia and my car is RHD. I'm not ready to sell my set just yet. I have extra pieces purchased over the years from adverts in the samba that I might need for this reproduction experiment.
Thanks for offering that mould solution. It looks interesting. On a similar vein, I've seen home injection moulding set ups that could achieve the desired result. I'm going to explore those and other options because the cost needs to come down as evidenced by the underwhelming number of people who have stepped up with interest and money so far.
I have a set of Mr Copello's billet trim that I can use on my car but I should focus on finishing the car and later do research on small volume plastic reproductions and in time replace the aluminium with something more authentic in appearance.
