Here is a bit of an exclusive for COTEP and one of my other local sites... before I post this little how-to on some of the other sites...
A fairly common question... how do you take the roll marks off a slide.
The answer... lots of time...
Start with a granite surface block with good, quality sand paper (3M) of different grits.
Here is the beginning of the slide, brand new Carbon Govt from Caspian...
Then, after a lot of time, and several sheets of 150 grit sand paper, progress begins to show... movement is forward and backward in a straight line...
Finally, almost all traces of the roll marks are removed with the 150...
After the 150, progress to the higher grits as high as you feel like going...
I progressed up to a well worn sheet of 1200 grit...
The work is simple, but it takes time, lots of it. Caspian roll marks are not very deep, but the above work is about 3 hours.
Questions, comments, critiques and suggestions welcome.
