This could be similar to the post just below this but im not sure.
I do mirror finish on my blades but im having a few issues getting there.
I grind usually to about 400 grit surface then HT.
Then I grind off scale and do final grind up too 800 grit rhynowet sheets.
Im making every effort to remove all the scratches from the previous grits... Or at least that I can see. Lots of water or windex, blade is fastened to a sanding block and im using a sanding bar with the paper.
when in finished with the 800 grit it seems to be completely smooth.
next I take it to the buffer... Which is actually a little on the fast side.
I have clean wheels one is green compound the other is white.
I start with the green and it takes about an hour to buff one side.
The problem now is as soon as I start buffing it just seems to bring out the scratches!
Too me it seems like 800 grit isnt fine enough ? Or... The buffer is too fast ? Or... Theres something wrong with my technique. I just dont know which but it doesnt seem right that the most difficult step is the hours of buffing out scratches.
The other issue im running into is after the pass with the white compound wheel the blade has a hazy look. Under light it shows lots of fine scratches from the final buffing compound. Is this normal and how do I get rid of this haze ?
Thanks again !
