I recently started to do some hollow forms with a homemade articulating arm setup. I'm using a piece of 3/16" square steel, with a curved end, as a scraping tool. I've only turned two pieces thus far, and found the hollowing process slow and tedious. Would a carbide cutter work better? What shape should I use for getting the bulk of the wood out? Should I be doing something different, or is the hollowing process slow and tedious, regardless of whether using a scraper or a cutter? Thanks.
