frosting wheels

[joella]

Hi, not sure where this post really ought to be, so sorry if its not in the right place. I was just wondering if anyone had photo's they could post of finishes they have achieved using various frosting wheels. Cookson's have extra fine, fine, medium and coarse for pendant motors, but its hard to know which one to go for when you don't know what the finish they give actually looks like. I don't want to buy them all - they are SO expensive! I'm wanting a nice matt white finish - someone suggested I just leave stuff as it is when it comes out of the pickle - but that doesn't work, it goes horrible and grubby really quickly, and doesn't feel nice either and I'm not happy with the results I've got by just using scotchbrite pads and wire wool, it scuffs too easily and looks a bit of a mess anyway (due, no doubt to my own ineptitude). So, anyway, that's why I was wondering if anyone had photos of their finishes along with info of which grade frosting wheel used. Thanks
Sue.

Sue, I cannot comment on frosting wheels as I don't use them. I was taught to add frosting by using a 4 inch diameter brass bristle mop on a polishing motor. The frosting is achieved by polishing the surface first with standard mops, then adding the frosting onto the polished surface by holding a pencil size stick into the spinning brass mop's bristles, which breaks their spin and makes the ends of the bristles strike the surface. I push the stick into the spinning mop's bristles just above where I hold the item for frosting, this is easier to show than explain.
This was the system I used to achieve the frosted background behind this crest.

Hi Sue,

Frosting wheels give a texture rather like silver sandpaper and are easy to use, provided that you can regulate the speed on your machine. Used too fast, they will shed their wires and quickly go bald.

The best one to buy, is the medium (blue) and with care will last me a year or so. The fine one is too delicate and the coarse one too destructive to small pieces.
They are best applied as late in the construction as possible, because heating and pickling reduces the effect.

Strangely they are not all that painful on fingers, but eye protection is essential. You can actually mask an area with tape to make a smooth border. They can also be used as an afterthought if the back of a piece looks scratched or untidy, because they will quickly improve unsightly defects. Dennis

The only one Ive used is the Scotchbrite http://www.cooksongold.com/Jewellery...prcode-999-ACR
which gives a satin finish like this:

this is with the Cooksons extra fine (yellow) wheel.
I use them right at the end, just prior to stone setting.
Here is a twit using one: https://www.youtube.com/watch?v=WzC-yPGpotQ

ETA: I've worn a ring finished with it a few times and it seems to be holding up well so far.
