  The fabrication of the first segment of ESS-Bilbao's RFQ has started in 2016. The segment, of about 800 mm in length, is an assembly of 4 elements: two major vanes and two minor ones. The assembly will be done by making use of carefully-designed vacuum polymeric gaskets instead of brazing. Electron beam welding has been used during fabrication of the vanes. Apart from conventional CAD systems, a home-made tool for vane modulation solid generation has been successfully used. Machining process from copper blocks to final elements is described in detail. Also, the software tools created to assess the quality of the vanes by analyzing the metrology measurements, particularly of the modulation, are described in the paper. In order to test and validate the chosen vacuum strategy, an aluminum model using the same gaskets as the final model was built and tested. Results will also be presented. The fabrication of the first segment is expected to end up in early 2017, so assembly, segment alignment and vacuum tests with the real device will also be included in the paper.
