Thanks to Sah-Ko, we got materials for our welding fixture really quickly. A 10 mm steel sheet works as a base, and the fixture is built from 3 mm sheet with a water cutter. The picture below shows the completed fixture for the front part of the framework. Due to some engine problems, we have to keep the rear open for minor changes for a moment still. The modular nature of the fixture allows us to start working on the front already though.
The welding work started today and it’s progressing neatly. More to follow soon!
