These last weeks, I focused the build on the uprights and suspension parts, as I received the lathe mill combo which I ordered in China 4 months ago...
My objective was to have a, in house, compact, versatile machine, with an attractive lathe axis-to bed distance : 210 mm.
I use it mainly on aluminum alloy machining, but it can also work on steel with very acceptable precision, until you accept to work very slowly....
The uprights are alloy made, 3 parts each and wheel hubs are based on AUDI hubs and bearings :
Rear : 82 mm OD , 37 mm wide
Front : 75 mm OD, 37 mm wide
The corresponding wheel hubs are from AUDI 100 ( same on A 6)and AUDI A 4 ; easy to find in France in junkyards ; from 10 to 20 € each ...
The uprights are Al/Zn ( 7075) for front and Al/Cu ( 2017A) for rear.
I worked from the design we made with my mate Christian ( Solidworks expert...)
The rought shape was made from alloy blocks with ribbon saw, and then precision finished on the lathe and the mill ( flycutter)
