Some more progress at last!
At the weekend we starting machining the first components that are required to build the prototype swingarm. The design has been sat in CAD for over a year now so its great to finally see some of the parts we've been looking at on screen for so long.
The first pieces to get underway were the chain adjusters. Inspired by the items found on GP bikes, they are simple in design with a fairly chunky appearance to them (they may well get refined later with more material removed).
We machined the side profile first on the CNC, then put the main slot through the middle before sticking them up on the end to machine the hole for the threaded stainless adjuster.
Next up we have the brake caliper hanger. This has been designed to sit with the chain adjuster block in order to prevent it from dropping when the rear wheel is removed. Again, I think its over-engineered and we can get away with a lot less material.
Here we have the result of the days work. These are the majority of the aluminium parts that will be needed to build the swingarm. The main blocks which bolt to the rear of the steel trellis are being machined elsewhere, due to a few complex angles that looked a bit too challenging for the tools we have, so we should have them back soon too.
