The machine shop finally delivered my 4" Carbon Fibre Bell Cranks.
They are CNC machined from commercial grade 1/8" thick carbon fibre sheet. This means there are no "voids" in the material that you often get with hand layered carbon fibre. The bushing is a high tech material similar to what is used in computer hard drives. It has a very low coefficient of friction so movement is silky smooth. We bush the line end holes with brass so that you do not have to bend tubing.
Cost is $19.99
