Quick update - another mini project within this project!

I was originally planning on using a good quality GL1000 master cylinder for my project, however...

The original CR750 master cylinder was a different part than any street models, it had an angled reservoir and a bigger bore/output to handle the twin disk set-up.

It is hard to see in the ACU homologation files, and from this image of the late Tommy Robb:






I managed to borrow a genuine CR750 master cylinder for a few days (magnesium), 3D scanned this and have started the process of reverse engineering it. The cap is slightly different as well! I will likely use genuine GL1000 valving within the custom body, so that it can be rebuilt if needed in the future.

3D Scan results:








The CAD progress so far:







Cheers,
CR21

Erm.....mind boggling to say the least! Your attention to detail is amazing.
So the big question is....how are you going to make it, from solid, 3D printing, casting?
Please keep a photographic record as this will be interesting to see👍

I'm beginning to wonder if this whole build is an AI generated entity,  it's so detailed & perfect.😃
