Cutting Welding Fixtures

Posted Leave a comment

While waiting for the 4130 steel to arrive*, we started by cutting the tooling fixtures with our ShopBot CNC router.  Using the dxf files from the builders database and 3/4″ plywood, we cut the 4 full sheets of ply which will provide all the tooling required to weld-up the fuselage frame.

 
*Living in Hawaii does have its disadvantages.  Most of the parts/supplies that we require cannot be sourced locally.  Long lead times will slow progress and shipping costs add up quickly.  The price of paradise…

Visit To Rainbow Aviation

Posted Leave a comment

Our project officially launched with a visit to Rainbow Aviation  in Corning, CA where Brian, Carol, and Jasen gave a tour of their facility and provided details of the EMG-6 motor glider.  Following the visit we decided that the EMG-6 would be the perfect platform for our project.  It’s a solid design that is configurable and the fact that all of the design files are open-source will make it convenient for us to configure the propulsion system as desired.
