I'm trying to lap a small object using 'diamond' paste. No idea if it actually contains diamond, I got this stuff off ebay for £5 in varying grits - from 40 micron down to 0.5 micron.
So i started off by rubbing it with 20 micron on a granite plate, gave it a good rub in varying motions and worked my way down to 3.5 micron. I can't actually tell if it's abrading any more as it's not getting any shinier. What am I doing wrong?
I do need to obtain an optical flat to verify my results. Feel free to make any other remarks.
