Several years ago, Richard Mann commissioned Wayne Mitchell of Dogrings.com to cast and machine type 47 uprights. Enough people were interested enough to let the project proceed. This what Wayne produced. The last two pictures shows the size difference between the TCS hub carrier and the type 47.
Yes . . and I don't know how many sets of 47 uprights were needed to make that project viable but there would (should?) be many more punters looking for Europa uprights.
However, when ever the idea of producing cast items is floated, the discussion invariably evolves into what might be accommodated.
Some people merely want to replace their S1/S2 uprights with minimal fuss . . and maybe there's the issue of at least the appearance of originality.
Others with a TCS will need the extra material for the larger inner bearing together with the different trailing arm bolt pattern.
Still others see the opportunity to add an ear for an upper link or extra mounting points for rear disk callipers. Of course, no standard spec is ever determined because everyone has their own idea of an upper link and everyone is using different callipers.
Thus, the project inevitably expand to at least three versions.
The well meaning person undertaking the project likely has one version in mind. For instance, an S1 owner may well not have access to a pair of TCS uprights and is therefor less confident of satisfying the TCS owner that the finished parts will fit correctly.
Likely also is the fact that in this day and age, the idea of one failure in service, and the potential liability issues flowing from that, would be reason enough for a private person to have second thoughts.
I'd guess it's a little different for a type 47 upright, too. While no one wants one of those to fail either, it's more likely that they're going to be race cars and as such, the idea of some perceived guarantee/warranty/liability doesn't loom so large.
Still and all, these on line CNC shops may be worthwhile investigating as they all seem to have a free quote option.
Is there a CAD file available and has anyone done this?
But if the quotes are higher than the cost of a TIG welder, well . . .
And of course, you'd be miffed if an axle broke anyway and dragged your nice new upright on the ground as your rear wheel sailed past and into the scenery.
