filing brass

I recently bought a thumb turn for my bathroom door. It appears to be made of solid brass. The problem is it's too long and I can't find anything shorter that fits my existing door hardware. So I'm looking to file off 1/4-1/2 inch. What is the best way to do that is? I tried an old file I had laying around, it didn't seem to do much/anything. A new file with a different cut? A dremel??

You could file for hours to remove that much material. I would see if you can figure out exactly how much material you need to remove and, if so, cut rather than file.

I'd use a hacksaw with very fine blade or a dremel with a reinforced cutoff wheel to get it close, and then file the end smooth. Brass is fairly soft, so any sharp file should make quick work of cleaning up the saw cut. Your old file is probably dull. The brass does tend to clog file teeth so having a file card handy to clean the brass out of the teeth will help.

A bench grinder would also work.
