1957 Lambretta LD 150 EV conversion

Had to drill new holes for the bushing housing because the previous hole were too big. I wasn't comfortable welding together such big gap. The new holes are more snug, i'm good with that.




Using the plate out of the hole, i made an insert. This insert should keep the housing from warping too much when welding to the arm.




Spot welded it to keep it in place.


Not winning that International Welding Award but my best friend Angle Grinder will help make it pretty later.

This is the best i can do. I'm showing you the two prettiest side.
Pressing the bushing in next.

 

[kingkongshrimp]

Congrats to me!!! The bushing survived the press.

More work on the swing arm. Should be able to tac weld it in place tomorrow.




Painted the hub motor an off white color. Trying to figure out a way to distress it to match the front.





The front.

Nice work!
The swingarm looks beefy, won't it be a bit heavy?

It's pretty heavy but i'm pretty skinny. Hopefully it balance out.

 

[kingkongshrimp]

Spot welded it together.



Here's a beauty shot!


The tire is not going in.
Anybody have any tips or tricks? It's like wrestling a gorilla.

 

[kingkongshrimp]

Searched online and found the zip tie trick.
It wasn't a piece of cake but it went on 1000 times easier than the first attempt.

The first attempt messed up my paint job but that's okay, i was looking for a way to distress the paint anyway.

Searched online and found the zip tie trick.

I was about to suggest it. you only really need 3 zip ties and also some soap. Soap makes it even 10 times easier. :wink:

I was using WD40, that's okay right?

 

[Dui ni shuo de dui]

Not sure WD40 on a tire is a great idea. I hope you cleaned it really well after that.
Soap just washes out with water, next time try it, works really well. :wink:

Ok, will use soap next time. Thanks!

 

[kingkongshrimp]

I'm assuming this is not safe. Any recommendation? Maybe use a bunch of washers to fill the gap?

Swing arm is finally done! Here is the passenger side.



Here's the driver side.



Here's the front of the swing arm. I'm not painting it. Will let it rust a little to match the rest of the scooter.

 

[kingkongshrimp]

Now the scary part. My brother loan me this 40 years old ibm pc computer. Never used one of these things before. Have to learn how to use it and then learn how to hook everything up. Kinda scary.

Doing the identification angle function.

The diagram was very confusing to me. The fat red wire from the battery connects to (NC) not the port with a red circle.


Here's what it should look like.

Yes, one of the many inaccuracies of the Kelly "documentation"...
Had to deal with that in my build, too...

Wow this is a cool build. Nice work and good job on the swingarm. Clearances could be tighter but some simple spacers should solve it and it isn't high power, looking good!

cheers

Hooking up the contactor was very confusing. The wiring diagram was no help at all. It was low res and the picture doesn't match the contactor Kelly sold me. It doesn't help that i'm not experienced in electronic.

My friend Resistor from the Modern Vespa forum patiently helped me with it. Here's how it's supposed to be hooked up.
Hopefully this helps someone.

Hi Tyler, What clearance are you referring to?

I only meant the axle fitting in the swingarm. But the pics might be misleading.

You mean this?

No, sorry. Around the motor axle. I see there's some black spacer there, is that part of the motor? And yes the brake torque arm could be supported with a tube over the bolt and vertical gusset below both welded to the swingarm.

Here's a crude scribble with my finger, hope it helps.

cheers

Oh yeah, that black spacer is part of the motor. I think there's plenty of clearance there.
I also added a tube to support the brake torque arm. Thanks!

Ah ok that looks great [emoji16]
