First, the lathe. Near it is the small air compressor for blowing crap out of the inside of a bowl. Behind the lathe is the DC, bandsaw, and planer, all of which share the 4” DC hose. Note the two banjos on the lathe.
Next is a photo of the “cup” and a cup life-center holding a scrap which I could make round.
And finally, a face-on view of the cup, showing that it’s just a jam-chuck (made from rock maple) with a shallow depression in the end. That’s a little scorched from whatever I was working on slipping at times.
Most of “making balls” is done either with a scraper or a carbide turning tool. Fewer catches makes for a happier turner.
