Sanding tiny round parts

[NOBLNG]

Some of you old hats may know this already, but I discovered this trick while sanding a differential that I modified. It works great on exhaust tubing seam lines too. Cut a 6” long or so narrow strip of your favourite sandpaper. Clamp one end solid somehow and hold onto the other end. Hold the part being sanded in your other hand and work it up and down the strip. You can vary the tension on the paper and also the angle of the paper from nearly flat to a 180 degree wrap.  Works great for blending things back to round after scraping mold lines too!

Thanks for the tip, Greg.  I hadn't seen that before and it looks like a very useful tool.

Will definitely be trying this method. Thanks

Good tip! Looks like a DIY partial version of FLEX-I-FILE. https://www.flex-i-file.com/

I might also try using a strip of the flexible sanding film (not paper) mentioned in

They have a lot of neat stuff on that site. Yes this would work similar to those files, but you can get more wrap- around with the manual method. The flexible sanding film would work better on inside curves for sure. It doesn’t clog up very easily either.
