Right...so here we are after a massive bump. Projects stands thus; * Bottom bracket, Magura mount and all tubes barring seat tube fully cad modelled * Pages and pages done on aluminium research with the conclusion that the 6000 ( 6061 ) aluminium will have to undergo 2 heat treatment stages to regain it's t6 temper. * Magura mount has been fully designed, and tested on CAD Attached are pictures of the BB yolk, Magura mount system, Frame assembly ( very rough ), dropouts and headtube. Tomorrow I'll have the first proper part assembly renderings finished. All comments welcome, especially possible improvements.
