Polishing problems again


#1

Hey, I asked this question a long time ago and never got any
satisfactory answer from anyone, maybe some of the newer members
will know. I’m polishing sterling silver, fairly large flat
surfaces on my pendants etc. but as soon as I hit the buff I get
STREAK build up of compound and if I continute trying to polish
using different pressure and amounts of compound the streaks get
worse and get polished into the metal. Needless to say THIS
SUCKS. I’m using a dust collecting polisher at 3750 rpm with a
small size soft buff. Is this because the speed is too high? I
don’t remember having this problem when Iused a dryer motor at
half the speed of this one. I can’t be the only one with this
problem. It doesn’t matter what compound I use or how clean or
dirty the buff is, it ALWAYS does this and I’m sick of it. Or do
I need a larger buff for faster speed? Is there a way to step
down this monster motor to half speed? Also, I’ve been using
WinOx to blacken silver (this is another question, unrelated) and
when I polish lightly to bring out the hilites and dip it in
ammonia to clean the polishing compound the amonia seems to
remove the black oxidation. I’m not having a good nite
here…help…Dave

Have had the same problem. I accredit it to one or both of 2
things. 1) Too much rouge on the wheel, and 2) although the item
looks relatively smooth, it is to ruff for the rouge you are
using. IE, using a Red Rouge, when you should be using a tripole
level!

Your pol.problems could be caused by too much compound
on the buff.You may want to try a larger buff also.For the
cleaning problem,Oakite has a product called BCR.It has no
amonia and it cleans very well.

I just ran into your question while going through old
e-mail.Here’s another reply.

I don’t like rouge. Try Zam.
Your buff may be too small.
Wipe the buildup off with your thumb while buffing.
Use a firm buff, not soft and fluffy.
Use a circular sideways motion.

Flat surfaces can be tricky.

Thanks Marily: so for a flat surface do you use one of those
yellow harder buffs with Zam? I’ve been using Zam but got a
negative reaction from alot of Orchid people who prefer rouges.

Yes, I like the Zam because it’s cleaner and faster. I think
some people like rouge because it “colors” the silver. I don’t
see that much difference.Yes, I use the yellow buffs.Make your
own comparsions and remember to keep the buffs and compounds
from mixing.

I use ZAM on niobium, platinum, to repolish turquoise, coral,
malachite and other soft stones, polish my hammer faces and other
finishing jobs.
