Topic tags/keywords: question

Can I turn brass w/ the same roughing scraper I use for turning wood? It is a carbide scraper. I’m just wanting to work a small ferule for an awl that I am making.

I’ve heard people say they do it, but I’ve never tried it personally.

I have used brass inlay before and regular turning tools will work for brass. It will dull the cutters faster than when used on wood so expect more frequent sharpening. The shavings will also be much slower and cuts should be lighter. There is no grain on brass, so the cutting is pretty much limited to scraping. Sanding is a bit of a chore, but then there might be other methods of cleaning the brass than low to high grit sandpaper.

Yes. I also use files held against the brass as is spins. High speed steel will cut brass.

I use files, rasps and sandpaper.

The HF clamp with the wood handle in the pic above has a brass ferrule on it that used to be a pipe fitting that you would use a wrench on. I was able to turn it down with a metal file and a gouge, use a little cutting fluid on it and it cuts down on the squeal of the metal on metal cutting. Also wear goggles under the face shield, you really don’t want the particles getting anywhere near your eyes.

derosa, That is similar to what I’m trying to do, knock off the wrench facets on a gas fitting ferule. Thanks for the tips guys, I’ll post my progress on this when I get back to it. I’m very new to wood turning and making tool handles was big motivation to get onto it.

Having a different lathe for turning metal vs. wood is historically a pretty recent development. When turning brass, you want a negative rake to keep it from grabbing. That means that the cutter edge will be dragging a bit rather than leading with the cutting edge like you do on wood. The carbide will do fine but so will regular HSS. Carbon steel will work as well but it takes a more delicate touch to keep it from overheating. Take light cuts. Keep the tool rest close to the workpiece. Maintain a strong grip on the tool. Don’t expect huge shavings to come off. It will look like the metal chips that they put in metallic paint. You don’t specifically need it for brass, but a light cutting fluid can help at times. I use a little squirt bottle of WD40.

Spinning brass is a different technique. That one uses tools that rub rather than cut and press the metal onto a shaped mandrel while it is spinning. One of these days I want to try to do some spinning but so far, I just haven’t had the time. If you are interested in that too, Penn State Industries has a rest and some tools. There are also some lathes that are set up for that specifically but not really common to find.
