Well I'm not to good to ask for help.
some background.
I hand sanded a 1095 blank to 2000 and i took it to the buffers and it is still cloudy when i take it out in the sun light, inside great , see my face good enough to shave. has anyone got or know of a video tutorial about buffing.
Any help on this would be nice. yes i"m humble.

Let me run something by you guy's. it seems I am using the same stuff as you all, so that makes me thing that i might be burnishing it. you know to much power on the buffer.
what do you think of this thought?

What's your buffer speed. You should be using a buffer thats runs at 1725 RPM's and a 3/4HP motor for an 8 inch wheel. If you're using a faster motor then you need to use a smaller wheel. At 2000 grit hand finish you should be able to finish it with fine white compound. Also you should only use 1 polishing compound per buffing wheel. I also use diesel fuel to help with the cut during buffing.
 
Use an old hacksaw blade to rake the wheel clean, apply some fine chromium green compound to the wheel. Buff with light pressure, don't push, and add buffing compound frequently.

Use a different buffing wheel for each compound, don't mix them. Store each buff in a bag to prevent cross contamination.

Shouldn't you use a larger wheel if you use a faster motor?

No, The larger the wheel you use the faster the surface speed of your buffing wheel becomes. Your other wise gentle buffing compounds will now be like little hammers and chisels. Here is where you will see little pock marks develop. In my experience it shows more on carbon steel then on Stainless steel. Faster is also dangerous. I'm sure I'm not the only one to have something ripped from my fingers and stick in the floor or take a chunk out of the cement, Could have just as well been my foot.

Here are is a brief chart in feet per minute of two different spindle speeds with various sized wheels.
Wheel size....4"....6"....8"....10"
1725rpm 1800 2750 3650 5475
3450rpm 3600 5400 7200 11250
