Drilling threaded screw holes in metal

[DirtyJester]

The piece might need to be re-plated afterwards as well.

The one displayed the OP wants drilled and tapped appears to be a matt finish rather than chrome so they should be fine.

Heat, or Liquid Nitrogen?

Anyway, I also have 2 laser cutters, couple of bench grinders, and will eventually get a milling machine. Need a couple of grand for one first though!

Aye, wouldn't mind, and google skills were not required . I work in engineering for a living!

The google skills was a joke in reference to the nitrogen bit matey

As mentioned it's actually very simple to make, all that is required is a four jaw chuck in the lathe You grip the bar with the curved side sticking out and face it off, turn it around to opposite side and repeat until you have your cube. When making the inner cubes you start with smallest one first, clever bit... use a slot drill and cut to same depth on all sides. Little push and it will break free Now go make one and get a few free pints

That was option 2, I went with the first one as it just seems easier to me . I can easily turn squares, I just can never be arsed to change the chuck over.
