What sandpaper should I use?

[DarkLightA]

In order to sand my cube, what type of sandpaper (like.. P40, P2500 ) should I use? Also.. Sanding would create stipes on the cube. Would this prevent it from moving fast? Should I sand away these stripes with fine sandpaper (about P120)?

Thanks

none, I always use a scalpel knife , this will leaves a smooth surface

You mean, one of those operating knives?

No, a hobby scalpel knife , used for model building etc

e.g. http://www.ehobbytools.com/contents/en-us/d22.html

I use the straight , but for small surface you can use the others

Wouldn't sanding the pieces cause less friction since there would be less surface area rubbing together? I havent sanded any of my cubes but I assumed this would be the case.

I would say 120-220 grit (both)...

I use a metal file (triangular prism shape) so I can get into tough spots and flatten off interior faces. Using a sharp knife can be dangerous. I do not know if surfaces that get roughed up by sanding will have worse or better friction than smooth surfaces.

Will using something that's good but scratches it up, and then smoothing out with low-grit sandpaper work though?

i used sand paper to make the cubies on my storebrought smaller and i left the plastic course, the cube has never moved so badly! i am going to use my scalpel on future mods...

Did you sand it with smoother sandpaper afterwards? What grit did you use?

I use 160 grit on my storebought cubies and it works nicely for the sides of the cubie but not the middles...

I would say you need a rougher grit for the inside but a smoother one for the outsides.

If your doing any significant modding like I've done on a 3x3 (4-5 hours), Then use a file. It takes forever to remove plastic with sandpaper. I go over it with a fine sandpaper afterwards. I belive 400 grit followed by superfine, prob like 600. Sometimes I use an exactoknife as well, or a razor.

Use steel wool on it after you sand it. It makes a very smooth surface.
