Humphrey’s tool of the week is a piece of equipment that, if you were using it, would require the use of both of the items of PPE presented over the last two weeks. May he present… the polishing motor! It can harm, it can maim but it can also make your jewellery shiny. Or matt. It has a spindle on either side to which you attach different ‘mops’. In the picture the mop on the left is soft and you put a bit of polishing compound (like brasso but better) on it and it makes shine. The mop on the right is made of scotchbrite and it makes matt (and it’s not as scary as this post might make it sound).
