mike_sekinger Posted May 17, 2022 Report Share Posted May 17, 2022 Time for another update on recent progress: The work to correct the previous CAD design and bring it dimensionally in-line with the Lotus drawing is complete. Based on earlier observations by Derek you can find an updated comparison between the v1.4 CAD, Lotus drawing and the new Aira CAD model. In addition to the dimensional corrections, both the upper and lower lug ribs have been increased and additional material added to those known areas of weakness. Various other design changes were made based on the CAM process and blending of the design. Visual comparions can be seen below highlighting the major changes (Aira design is copper colour): The 6082-T6 billets have been dispatched from the supplier and are on their way to Aira. This equates to 750Kg of raw material for the 1st production run. Each billet is around 30Kg and the CAD model is calculating that each finalised upright will weight approx. 4.4Kg. A 3D model of the LH upright has now been prepared and will be printed over the next week in order to enable a further physical checks. Each of the sections will be printed independantly to maximise on printer orientation accuracy and also enable any sector specific re-work if necessary. Lastly: In order to secure the full initial run of 10 pairs of uprights, additional billet was ordered. If there are no hiccups during production, there could be a further 2 pairs available from this 1st run. If anyone is interested and wishes to get their names against the potential over-supply, please PM me.
