I wood turned a bowl from glulam beams I saved from the pool house that we demolished to build the shop. I cut an 18 inch square into a circle on the band saw. I worked on the bottom of the bowl first, making the shape and a mortise for the scroll chuck. I finished the bottom completely before I turned the piece around to work on the inside of the bowl. The soft fir cut easily but it was hard to get a good finish on the end grain with the lathe tools. I had to do a lot of sanding, starting with my grinder then to my drill with a sanding pad. I finished the piece with tung oil.
