I run at my lathe's slowest speed (750 rpm). Too high and you'll tear the abrasive right off of 'em. (DAMHIKT)

I don't bother to adjust the belt after final turning. After final turning, abranet at speed - 2400-3600; micromesh at the same speed. BUT, at this point you are not removing material, just removing scratches and polishing.

I do not use a lot of pressure, let the pads do their work on the scratches. I use water liberally, wipe of the slurry, next grit.

So, 2400-3600, whatever last turning speed I was at.

Aside from speed....pressure and touch is everything. Do not press hard on the pad. Keep it wet. I use a spray bottle. I vary the speed. You'll know after a few finishes.
When I'm satisfied with the sanding...I finish with Novus 3,2,1.

Uh Mark , the slurry you are removing is material (finish) that has been sanded off to reduce the barrel diameter by an amount about equal to twice the depth of the deepest scratch . It is only immaterial if that process hasn`t appreciably changed the match to the components . Polishing with wax temporarily hides scratches , but customers will probably find them , sooner or later .

I micro-mesh at about 1000rpms. I use light pressure and plenty of water. Seems to work for me.

I always wet sand with M M and usually run the lathe at 2500 rpm.

I am guessing I am in the 1000 range. Bump it up a little after applying CA It becomes a guess. I too use water all the time. Do not spend too much time with them and finally add a polish. If i can not see scratches with the naked eye it is good enough for me. Have yet to see anyone walking around with a loop when buying any of my pens.

I mm at my last turning speed, using a very light touch, and only for a couple of passes before moving on to the next pad. I dry mm wood and wet mm acrylics, aluminite,etc. Question for those who wet mm all the time: does that not introduce moisture to a wood blank, thereby increasing the risk of a cloudy CA finish (assuming you use a CA finish)?

Interesting point. I don't use Micro Mesh on wooden blanks; usually I don't go higher than 600 to 800 grit on a wooden blank unless it's something oily that doesn't like a finish on it. In that case I have grits in the 1000 - 2500 range that I use.

Speaking of grits, is anybody else hungry?
