Hey gang I'm making some parts out of delrin; they've got fins on 'em and when they're cut to length the fuzz is everywhere! I'm thinking of using my brass tumbler with walnut shells unless someone's got a better idea. Here's a link to the problem: https://www.flickr.com/photos/steamb...7673545442262/

Looking at the picture. it looks like the fuzz in one one side. So I am guessing the parts were cut off on a table saw.

So maybe you could rotate the part as it is being cut off so less fuzz in created. So the saw blade in always cutting into the part. Bad description, but I can not think of a better way to describe it.

You might also try a different saw blade or maybe a brand new one.
