CR750 replica build
CR21:
The chinpad mould is complete, first out of the tool looks good ;D
Disk spacer and rear shock mounts complete as well:
Cheers,

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:

Laverda Dave:
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👍
McCabe-Thiele (Ted):
I'm beginning to wonder if this whole build is an AI generated entity, it's so detailed & perfect.😃
CR21:
Hi Dave,
This part will be machined from aluminium most likely. No real need to cast this part it as the post machining set-up is quite complex and the quantities are well - very low! I have had some DMLS parts produced before, however the same post machining challenges come into play (and sometimes poposity!). I will keep the thread updated as things progress.
Ted - I wish, I think it may have been a little quicker if AI was involved and hopefully with a few more mistakes! ;D
Cheers,
CR21
