Triumph Tr6, 3d printed large scale

[François]

So the calipers are finished.  I added the rigid fluid line and the brake pads. I also started the rack and pinion.  I'm aiming at a working rack but I've never modeled one before. It will be interesting to see if I can pull it off.

Not "if" but "how"...

Finished the wheels today and the front axel. I wanted to find an easy way to remove the wheels. My first idea was to do like i did with the Hydra, to use the center cap as a screw. But then I thought of another idea,  magnets.  I'll inbed 2 magnets in the each hubs and 2 in each wheels.  I'll test it before going final with it.

The magnet idea

I've been doing some printing test these past few days.  I have a working rack and pinion with working rod ends. I still need to refine it here and there but it's close. And I've ordered a miniature steel universal joint (5$ on Temu) to replace the printed ones as it will probably be a weak point in the steering mecanism. 

All components in the rack and pinion 

And assembled 

Working rod end with rubber booth (the boot comes from an RC boat I think)

I also printed a complete wheel assembly,  I am very pleased with the result.  I tested my magnet idea to hold the wheel to the rotor and it works very well. It will be a breeze to remove the wheels to show the suspension. 

All components in 1 wheel 

And assembled 

And the real one

It was noted to me (thank you Messer) that I made a major typo on the tire. It's should be Pirelli, not Pirelle. Error fixed ! Sorry to all you Pirelli fans and to all english teachers.

I just thought you were trying to avoid any copyright infringement issues!

If only that was reason! Nope, just a dump typo. I repaired the typo and modified the P to look a bit more like the logo.

the first sub assy is done,  the rack and pinion.
