Mirror polish

[theismaluns]

Help please! I'm trying to get a mirror polish on a completely flat surface in pmc 3 but I seem to get it to a nice shiny finish still with what look like drag lines. How can I stop this from happening? Thanks!

MicroMesh sheets are ideal for this,They are rubber backed abrasive sheets. Lay them flat on the bench and rub the metal surface on it.

You only need about four grades, starting at say grit 2400, then 4000, 6000 and lastly 8000. they go on for ever and can even be washed.

Thanks Dennis! So just that I get this right as this has been doing my head in and I have wasted so much product. We roll our piece and use a cutter let dry for 48 hours then we sand using 3m sponges by three grits then we put in kiln then we use wire brush then we would move onto these sandpapers? Do u need to use polishing papers as well or just these? Do you rub each grit in the same direction or opposite directions for each grit? Thanks!

What are you using for your final polish. Are you doing it by hand, pendant polisher or bench polisher?

[theismaluns]

Ours on the left and the finish we are after on the right

It's difficult to see drag lines from your photo. There seems to be some texture on the raised part
