Question About Micro Mesh And Sandpaper.

What is the difference between sandpaper and micro mesh when tuning a nib? Assume that they are both in 5000 coarse.

Micromesh and sand paper grit sizes are not the same unit of measurement :

secondly ,

 

they perform differently ..

 

Valuable lesson about Micro-mesh sanding pads!

 

 

Disclaimer :

I know nuts about micromesh and sandpaper.

I just googled....

You are going to compare the regular Micro-mesh (2nd) column and the ANSI or CAMI USA column to compare the sandpaper grit and regular micromesh grit, then the last column which is the size of the abrasive in microns.

 

4000 Micro-mesh is roughly (sorry) the same as 1500 gray wet-or-dry sandpaper which is as course as you should ever use on a nib, and coarser than most people recommend for use on a nib. This is what we use for fast, initial shaping of a nib. Finishing and polishing is with 12,000 micro-mesh, which is finer that 3 microns according to the table. Sometimes that is fine enough. We tend to use 0.3 micron film, and some go as fine as 0.1 micron for the final smoothing of a nib.

 

Because regular sandpaper is glued to paper paper which is usually used on a hard surface VS micro-mesh which is somewhat resilient or is mounted is on a pad, the way that the nib interacts with the abrasive is different. It is possible to create baby bottom on the nib by over doing it with micro-mesh.

 

Note that each manufacturers abrasive is a bit different, so the actual coarseness of the paper may vary from brand to brand.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
