A couple of years back when I was in university I took a product development elective for my engineering degree. I wanted to do something XS related and at the time there was another thread on the Mr Riggs style clutch doing the rounds so I thought it would be handy to look into something like that.
So I ended up writing a report, cant remember how long but prob 10k words at least going through the whole thing from start to finish, calculating the forces involved, diameters of slave cylinders, the materials, o-rings, surface finish, tolerences, processes etc. I made some spreadsheets and did some drawings, even 3d printed some prototypes and stuff.
It was a pretty decent body of work, the only problem is, all my university stuff is currently at my moms house about 70 miles away and here in Ireland we cant travel more than 5kms till at least April so I'm afraid I'm no help until at least then.
