Problems with Emery buffing

[mainaman]

HI all,,
I am working on razor restorations, recently got Baldor 1800 rpm buffer to facilitate my work.
I use greaseless all the way to 600, then Emery. Emery is supposed to remove the 600 grit scratches and leave near mirror finish. To speed up the 600 scratch removal I run the blade at different angles to the wheel. My problem is after the 600 grind marks are removed I am left with fine scratches from the Emery wheel. My question is what is the right way to work with Emery, to avoid my problem?

Thanks.

Welcome! Well, from what i understand, the emery is 'roughly' the equivalent of a 400 grit, so i'd say that's where your problem lies straight up, it may be going backwards. After a 600 final sand, it's more than sufficient to move onto say, a brown, or final finishing/color/dazzle compound. Alot of people just recommend the black emery, if you still have scratches afterwards, and it saves a lot of time, but really, if you've done the greaseless well, it should be fine to skip that step in my opinion

Thenks, for the reply.
By brown you mean Tripoli bar correct?

Yes, i believe so, i just know it as 'the brown one' hehe

I suspect that the emery is not your problem. I find that emery produces a really nice, scratch free finish on aluminum and on steel. You may have some contamination on your buff, or, more likely, you put some scratches in the razor with the coarse greaseless compound that you did not get out with the subsequent finer greaseless compound.

In my work I find that always this is the case. I get lazy and don't sand as much as I know I should, and bingo: got me again. I have to go back and do it all over again.

That could also be the problem, shine some direct light on it from different angles and check to see if there are any small scratches. I would then sand wet in one direction with the 400, then go the opposite direction with the same grit, to try and reveal and scratches that may be there. It won't hurt it, because when you buff it again with the emery, it's the same grit
Also, are you religiously and surgically cleaning the metal between each (even sanding grit) steps?

I use brake parts cleaner after every step.
I talked to Caswell customer service, and they told me emery is in the 300-400 grit range, so this might be a reason for my problem.
Tripoli is ~600 grit, White rogue is 800 grit. I will try tripoli after 600 I hope it will work.
I think that I move to the next grit on greaseless too fast and do not completely take care of the scratches from lower grits.

I do polishing for a living first use the black emery with the sisal wheel after finishing with those, you need to polish them again with a treated vented buffing wheel now using white compound, polish hard and the shine will start to come , Note this is for polishing steel or stainless steel, always use 10 or 12 inch wheels (or bigger) and try to put two or three wheels together to make it wider. If you don't belive me check out my web page Metal Polish and Chrome Services you can call for questions after 4Pm central time ask for Eddie Guzman

thanks, I did try sisal and them spiral sewn, both with emery.
white rogue after that, it is very slow because the wheels are 6" . I am new to this so for now I try to avoid bigger wheels, but definitely will try in the future.
