I have spoken to friend who is a retired plastics engineer with nothing to do.

Now that he's made scary faces for all his grandchildren for Halloween and all the little odd-shaped parts that he can use for things around the house, he has run out of things to do.

I'm thinking oif approaching him with making parts for the cars, especially those which are no longer available.

Some parts on the list now are

1934-57 Citroen Traction Avant motor mounts
1955-75 Citroen DS/ID motor mounts
1960s era MB 4 and 6 cylinder valve cover gasket
Citroen radiator shock mounts
Hood isolators from several Citroens and possibly MBs

I have thought about:
- Rebuilt MB W123 motor mounts and engine shock dampers
- Rebuilt W126 motor mounts?
- Hood adjustors


Your thoughts please!

Maybe some of those vacuum valves that are always getting broke when messing with anything around the FI, fuel filters, or oil fiter.

I had thought of molding engine shock mounts and selling them on eBay, but I worried that M-B's lawyers might have something to say about that.

Why would you make the motor mounts themselves? Those are pretty plentiful.

I love the idea, though. Could you do seals? I'm trying to remember what parts are NLA...

2 Samuel 12:13: "David said to Nathan, “I have sinned against the Lord.” And Nathan said to David, “The Lord also has put away your sin; you shall not die."

the throttle pivot ball that mounts on the firewall of the 116 MB is NLA... it's nothing more than a plastic ball on a shaft held in with a circlip... THAT would be a good thing to manufacture...

also, the engine SHOCK mount is supremely pricey... you might be able to make a "repair part" to sell

I have an aluminum prototype part needed to convert our beloved OM617.9XX engine from the mechanical water pump to an electric water pump. Can I send that right now and get one made out of plastic which will survice the hot and cold cycles ? No real torque or stress on the part other than engine vibration and heat and cold cylces and constant contact with antifreeze ... I can send it today if it's doable.

Some sort of repair kit for W126 door panels with broken retaining clips.

Maybe those things that go between the arm rest and the door panel on first gen 126s?

How about some cup holders for the center console of 123's?

The little rubber ramps on the door strikers. It would be great if those were replaceable without buying the whole $$$ thing. I bet they could be made out of some type of plastic which would be soft enough for smooth operation, yet more durable than the rubber.

Virtually anything made out of a thermo-plastic resin will entail injection molding and the cost of the mold making can be prohibitive unless you're able to spread that upfront cost over a many pieces, unless it's a very simple part of course.

If you're using urethanes and two-part silicones the cost of any material is quite high, and you'll probably need some fixtures or molds but they can be made from many different materials.

If you're using natural or synthetic rubbers like neoprene you'll need fixtures/molds and the ability to heat cure and stabilize the parts.

The part will determine the range of appropriate materials and the part and the material will determine the method of manufacture.

That all being said there are certainly a large array of plastic materials out there to experiment with, I recently used a DEVCON 2-Part to rehab SDL engine shock mounts. They came out good but the material is not elastic enough compared to the original rubber so I'll be doing another set with the DEVCO softened up some.

Bonding plastic to metal such as engine shock mounts and engine mounts take some extra care and preparation to achieve a strong and lasting metal to plastic bond.
