Question from Japan ......! Please advise. I’m restoring Formichino without front lense cover type . My Formichino was lost these area parts when I bought it. I bought a headlight unit and replica plate that was made from FRP(?) from RUMI club. But these were not fit. Next time I bought aluminum plate from eBay seller. The seller said that is NOS part. But it wasn’t fit,too. Must I cut it for fix??? Or completely another reason???

Good morning, yes you will need to trim the aluminium light shroud, the original ones where plastic and when new where flexible to take up differences in the fit between the body castings and the headlight, the remade ones are made of non flexible material so you will have to carefully trim until you get the best fit you can, most of the original plastic ones have also now gone hard and these don't always fit anymore. Hope this helps. Regards Graham.

Thank you Graham san!
I wondered why I can’t set these.....
I hadn’t looked the original plastic part.
I’m happy to look some pictures if you possible.

The aluminium one you have would have been cast from a mould of the plastic original type, so, the shape and look is the same - except the plastic ones are thinner.
I have many aluminium ones that I brought back from Argentina and none of them are a nice fit.
You will find it easier to use the fibreglass one you have as it has a fraction of flexibility and is easier to file. Also most of the plastic ones where red. But I have also seen blue and white. If your formichino is 1957 or earlier it would be correct to use a turning front light, not only are these a nice "quirky" feature, but can be made to look a lot neater than a poor fitting later shrouded type.
There was also a replacement "large lamp" unit available as an accessory in France in the 50's 60's by the company Marchal, that comes with its own specific glass cover. If you can find one??
Regards, Graham

Thank you Graham san! Great knowledge! I wondered what was that glass cover.

I will file aluminum one this time. I hope that I will find original plate ( no problem, even damaged one) for making better replace part.
My friend’s company is making parts from acrylic plates. Maybe he can make if it is simple heat press shape.

you hugomez san! Nice pictures! I had looked your pictures on internet but couldn’t understand this construction. The seller of my aluminum part said that my part is original :-) I believed it and I wondered why I can’t set it......

Do you have a picture of back side of this plate? Do you remember the thickness??? It looks about 1-2 mm....

Hi Satoshi, as far as I know, and as Graham mentioned previously, the original one was made in plastic. I do not remember the thickness of it.

Hopefully another member of the forum that has one out of the scooter can measure it for you. Anybody?

Sorry I do not have any photo of the back side of it.

Greets,
Hugo

Hello Satoshi,
The broken ones in my workshop measure approx. 1.75mm.
This part seems to have been made of a material resembling polythene which cannot be repaired using any adhesive that I know of.
I repaired a cracked one once using sticky tape on the rear face and then had it reproduced by 3D printing.This produced a good result but was not cheap.Once the software has been established, however,any number can be made.
Hope this helps.
Michael

Thank you Michael-san!
1.75mm! Very thin!
Can I buy your 3D data at shapeways etc?
I think 3D printing is nice idea because I thought to use FRP at the first time. But as you know, FRP isn’t soft.

Arthur-san, thank you for your pictures!

This is the part of my dream ! :-)
It looks like as my replica soft one.
For comparison, what size of diameter of this lense hole???

Best Regards
Satoshi

Arthur-san! Thank you so much!
But my replica parts are opened almost same size hole....
Ummm....another new mystery.

Reason 1?
My head light unit is wrong part.

Reason 2?
My head light cowl is not for this type.

How do you think about????
