[size=+2]Abrasives in Micron Scale: Grand Logarithmic Grit Chart[/size]
I would like to present a new format of grit comparison chart. In the chart I seek to display the information as compactly and intelligibly as possible. Since abrasive particles sizes cover several orders of magnitude a logarithmic scale is most appropriate. A logarithmic scale also has the property of equidistant spacing for any geometric progression, meaning that a theoretically ideal stone series will be uniformly spaced in the chart. Stated another way, two grits that differ by a specific ratio will be a specific distance apart on the vertical axis of the chart whether they are 1.0 and 1.5 micron or 200 and 300 micron.
I must stop and give tribute to Komitadjie's Grand Unified Grit Chart which was my inspiration for creating this one, and after which mine is named in homage. While I expect the charts to be compared they are independent entities. None of the data from Komitadjie's chart was used in the creation of my own except for the BRKT and Spyderco ceramic approximate values which I included for completeness. All other values I sourced elsewhere, though some sources may be common to both.
I spent considerable time assembling this chart therefore I am not releasing it into the public domain. I retain control over its distribution and use as detailed in the README and LICENSE files. I ask that it only be shared by linking to the original source: http://myplace.frontier.com/~mr.wizard/GLGC/
Please see http://myplace.frontier.com/~mr.wizard/GLGC/README.txt for important details about the chart including how to interpret it and what it does and does not represent.
The chart and README will be updated if and when corrections or improvements are appropriate. Previous versions as well as additional charts may be made available in the /GLGC/ directory.
I am soliciting feedback on the chart presented above. Any corrections and all suggestions are welcome.
Please ask any questions you have regarding the chart and its interpretation. Anything that is unclear shall be additionally explained in the README, and potentially modified in later revisions.
As explained in the README file I chose to limit the range of the chart to keep it compact. A format I considered is to include additional scales to cover the macrogit and submicron ranges. Please see the file "GLGC RC2.png" in the directory linked above. I request feedback on this layout as well.
