Ayup rinderpest from Derby!

Quite a few people from Notts, Derby now!
Like that Ugly git John S I don't mind helping out with a bit of turning etc, My first machine had M10 metric thread lead screws and I got pretty good results with a decent nut, Can always upgrade later mate if you get into it!

I did the below with standard 10 x 1.5mm metric threaded bar, Its about 30mm in diameter and done with a 1mm ball nose. Went about 1.5mm deep.

Sorry for crap pic was scanned in off the block of 20mm thick ally
