And so it begins. This is a thread away from my bike rebuild one that has been going on for...……. well too long. So this is the beginning of a new thread toi specifically cover off the building of the first of what I hapoe will be many, Carbon fibre swing arms to suit the 91-97 Supersports.
First up has been the design. After a lot of umming and rrrring I came up with the design that I am going to use bt a process of elimination of what was required to make it a reality. Going with a slab sided design with a cut out in the both sides that are symmetrical meant that I would get the same sort of stress responses for both sides. Adding additional surface area also means that I can play around with laminates as I please once I do the moulds for the finished item. This first one is going to be made on a light shell made of a number of different portions off the plug. Each part over laps another part for bonding and sealing purposes. and there are some internal structures that have to be made as well specifically around the mounting point for the rear shock. As this first one is going to be built as a test/road use item it is anticipated that it will finish up being heavier than future ones will be. For the fittings I have them being machined at the moment though I do have the top shock mount to sort out over the next couple of days. manufactured from 7068t6511 they are a lot stronger than I could have possibly imagined so it is really the transition from metal to alloy that I am really concerned with. The assebl is compatable with all other components from the original bike though I have been updating parts of the assembly as I go.
So where we are up to now is that the plug has been completed and I have made the first part of the shell. Just need to wait for it to cure before removing it , cleaning it up and then get ready for the next part.
