Lola T-70 Mk III

[Scale-Master]

I designed and then grew the rotors several times over the course of a few months. The detail I want is just not something my printer can do on both sides. (One side is great.) I redesigned them adding more material so I could post-machine after growing them, but the material is too brittle when cured, and too soft and pliable before fully curing. I was able to make them look really good after machining, but every one of them had micro fractures (or worse) that would show up under paint.
The good side of them:

The rough side of them before machining:

So after way too much time and effort without acceptable results, I went back to my original plan to make the rotors before I got the 3D printer… Good old machining.

First I milled in the rectangular vent holes around the perimeter.


Then I cross-drilled 60 holes in each side.

this is crazy man. awesome work!!

[Scale-Master]

Thank you kans0002!

As satisfied I was at the time, the more I looked the more I thought I could do better… So more time on the mill and now I think I have what I want. These cross-drilled holes scale out to ¼ inch in diameter.

amazing work!

Outstanding job on the rotors!

[Scale-Master]

Thanks 360 & nugundam! I couldn't leave well enough alone...

I decided to go with my earlier rotor configuration; slotted and cross-drilled.
Raw rotor blanks cut from high-pressure cast blank aluminum composite material.

I milled the vents around the perimeter and faced them.

I cross-drilled and slotted them. They are directional.

This is the natural cut finish of the material.

Very cool.

I got the Wilwood calipers painted, going for a ceramic finish look. They are Corvette retrofit units I designed in SolidWorks and 3D printed before hand-finishing the masters then casting resin copies.
I used the new Tamiya LP-6 Pure Blue for the color.

The new 3D printed caliper brackets I designed and grew to mount the calipers have been attached to the front spindles.

[Scale-Master]

I carefully saved the rear caliper mounts on the hub carriers when I cut off the molded on calipers from the kit. But those had to go too because the larger Wilwood calipers couldn't be mounted to them. Again, these are 3D parts I rendered in SolidWorks and printed.

[Scale-Master]

Composite brake pads. They have been seated and used just a little bit…

[Scale-Master]

The pads are installed and the calipers have been dry set up on their respective bracketry.
The rotors, hubs, calipers and pads are all scratch-built. The slide pins are polished steel, but still more hardware to machine for the calipers.

This is pretty nuts, the detail you can do in big scale! Looks great Mark.

Thank you Alex!

I had to make the coil over shocks next to continue mocking up the suspension.
Shock bodies…
