Machining 9 carat gold

[Lakc]

If your going to play with precious metals, a scale (and a damn accurate one) is going to move right up on your tool list.
No better way to cause trouble then to have someone give you 90g of gold round and think they gave you 1kg...

The darts in the photo are hallmarked silver (925) at the Sheffield Assay Office. Presumably they are 18 carat gilded judging by the colour?
