Repair or remanufactured

[Black500]

Hi, I am not a welder but was hoping for some advice. I have this part from a modern classic car folding mirror shown below which is NLA and wondered if it’d possible to repair or is there a way of making a new one ? It’s heavy for its size but not magnetic. I took it to a gear manufacturer but they were stumped due to its non consistent radius ( crescent shape ) .

Many thanks

Welcome to the forum,
I'm guessing that its cast aluminium, if it is I would build it up using tig and hand file it back to shape, not a difficult job just a little tedious,

 

[awemawson]

It'll be something a bit harder than aluminium I think - possibly an aluminium alloy but more likely Zamak. If so beware tigging as it'll melt away as you watch it

Take a mould from it and cast one?

 

[MoreWellie]

find a good secondhand one? guessing it cannot be that old if it is a folding mirror

 

[Cobbler]

Carefully drill & tap the remains of the teeth, screw in pegs & file the shape of the teeth into the pegs. It's a fiddly as the screws are so small & has to be done accurately

Thanks for the prompt replies. It’s from a 90,s car, hardly any made with this spec & only for Japan market, Been looking for a year for 2nd hand one.

So I have three different options already. Just need someone skilled who thinks like you guys in the Glasgow area

Have you tried other models from the same manufacturer? The same parts pop up on different models, an example I came across is a hilux surf tailgate window motor is the same as a UK spec MR2 passager window.

what car?

Have you tried https://www.amayama.com/en? I've had quite a few bits and pieces for my JDM Surfs from them.

 

[rikrobson]

If you are lucky and it is zamak or Ali then you can get some Hts2000 rods And build up the missing teeth then file them back.
Hts2000 are an alloy with a reletivly low melting point but is harder than zamak
or ali

You'll just need a blow torch ans some files

What car might help. All we know is 90’s and Japanese market, so could be anything...

 

[rikrobson]

I have tried on some mystery alloy which melted before the rods did but they work time on ali and zamak if you are carefull

Nice, it's a common failure on a Surf!

Edit: what car is it???
Edit again: I would be surprised a Japanese car manufacturers would make a special part that wasn't on other models!

Would these work or are they just a gimmick ??
Think it's brazing not welding.

 

[rikrobson]

They are like the Hts2000. That have worked for me in the past

 

[cumbriasteve]

If all forms of welding or brazing fail then this is what I would do:

Make a cardboard template to ensure I know the original shape.

File the damaged teeth back until I have a flat surface.

Shape and stick a length of mild steel using pins and araldite to secure.

Using the template file the teeth profile into the newly applied strip.

What does the mating part look like? Looks to me like it could be a small gear wheel. If you could get a slightly bigger one of those, you could file all the teeth down on the above.

Many thanks

Any half decent toolmaker could make one just using measuring kit, gauges and shadowgraph to get dimensions. it's either a ellipse or some kind of convoluted radius. Make it from putting several radius together (old way of making a ellipse that is close enough to the true form)
Shadowgraph will have no problem measuring the teeth.

But to get a toolmaker to make will cost a fortune.

Thanks for all the replies. I appreciate all the ideas. Thought it was a lost cause but now there is hope.

Didn’t want to bore you with the car details but it is a 1994 MB SL model 129, built in Germany for Japanese market with specific spec. The powerfold mirrors were unique & design changed after 2 years. Imported to UK in 2016. There’s over 200 SL129 mirrors for sale in eBay, not one match. Can’t find a decent Japanese 2nd hand breakers for European cars. It’s a very disposable car market out there.
