Quiet on the blog but it has been busy in the workshop with a number of projects progressing. My VSCCS application has been approved in NSW and I am just waiting on a response from the WA Department of Transport. And the picture? Well one of the projects in progress is a rebuild of a 1974 Honda QA50. This is the engine casing after a quick bead blasting.
As mentioned previously on this blog, this is a motard style conversion of a Honda CRM 250 using a 2007 model Aprilia RS-125 wheels, discs and front brake caliper.
A custom bracket was designed in Solidworks to adapt the radially mounted caliper to the original brake caliper mounting holes. Designing in 3D allowed the part to be simulated (FEA) with heavy braking loads and calculate the factor of safety, stress, strain and distortion.
With the development of so many consumer, DIY and kit CNC mills, lathes, Laser-cutters, 3D-printers and other assorted NC machines that line our wishlists it can be easy to forget that a lot can be accomplished with manual tooling.
