Modern Vespa

while I'm waiting for the welding specialist to have some time for me, I went further on some parts.

The rust made its work under the fuel tank paint



Epoxy primer, then bondo (NO BONDO ON EXPOSED METAL !, common mistake in body shops), then sanding



another coat of epoxy primer



It still needs to be lightly sanded before a thick coat of surfacer, then final sand before paint and clear. I try avoiding sanding before 1 week, this gives time to cure properly. After using surfacer, the elements will be UV cured to speed up the process.

Same process on the mudguard









I can't find the picture of the final result... Will show later

Brake pedal is in poor condition, dirt, grime, oxydation... Orange and black paint overspray ! Nice









After sanding and polishing, not perfect but that is what I wanted as the finish look won't be mirror finished but brushed. I will brush the surface later and show the process if you are interested in.



For now it already looks way better





I bought a central spare wheel holder, gave a coat of primer to check the surface condition





The finish is terrible ! How can you sell brand new repro parts like that ?!
Not acceptable in this condition for the rebuilt, I spend a lot of time working the surface





The flywheel cover is still in Ok shape but has a ding





Now it looks good after some hammer/dolly time



The engine is dirty as hell ! God knows how many years of oil and dust have accumulated onto the surface, most of it is rock solid, it takes a lot of time, a lot of swear, some diesel fuel, various brushes...









Is the seal broken ?



Now the engine is in better outside shape, (still very far from my OCD standarts but that will come later), and on the stand, ready to be taken apart.



I still have to clean the carb box



The flywheel is in bad shape, some stupids probably used something as a lever and bent the flywheel on 5 or 6 points along the perimeter... I want to re-use this one because it works first, and it is original.



I was thinking of heating the aluminium with a torch and hammer dolly, is it a good method ? Is it physically possible to bring it back to its original shape ? I would be super easy with steel, but aluminium ?

That's an incredible amount of goo on the engine!

Be very careful with the fan. The metal is funky and tends to crack easy when worked. It's very difficult to weld and has lots of porosity. Had to repair mine. I've never seen a pink glow while tig welding before.

I think I got 3 or 4 kg of goo at the end !!

I'll give a try with heat on the flywheel, hoping for no crack

I took care of the flywheel.

The set up
using a piece of thick aluminium waste as support



I hit a wood block with the hammer a few times after heating the aluminium with a torch, then heat again, then hit... going from this



To this



There was 5 spots like that, everything went ok.

Some of the blades are in bad shape



I used the file to correct this



Next will be a coat of thick primer and paint. I'll use original Max Meyer paint code (from PPG) to finally paint and clear the flyweel.

Nice fix!

Well done saving the fan!
