amazingKevin,
Sorry it's taken me awhile to get back to you. I've been busy in the shop planing wood and cutting bowls. Thank you so much for such a nice compliment. These bowls take some practice, but anyone willing to invest some time could achieve good results.
The center of the wood is the bottom of the bowl. There is no waste.
I'm pretty pleased with my shop. I got the planer for a steal on craigslist. I got the titling spindle sander for xmas. This is my 3rd scroll saw. Started out with a pinned one with one speed - what a mistake. Outgrew the pins in about 2 weeks. LOL Next machine was also cheap but did have variable speeds. But the mechanism for holding the blades was so cheaply made, it kept falling apart. My husband got tired of helping me repair it constantly and surprised me with the DeWalt. I use the tilting spindle sander for sanding the interior and exterior of the bowls, but many people use other tools for sanding the bowls. Carol Rothman's book suggests several different tools to use. I have not tried any of these, but it seems others have much success. I buy rough cut lumber 1 1/2 inches thick, so a planer is necessary. Some of my bowls are glued up using the edge grain glue up method, so again a planer is necessary. I also use a mouse sander for the edge of the bowl. If you were buying finished lumber that wasn't warped, you could also get by without a planer. If you are serious about bowl making, invest in Carol's book. It also has the equation on how to calculate the angles for cutting. That is a must have for bowl making.
I make these bowls for fun. I have given many away to friends and relatives. My choices were to either rent a large storage shed or find an outlet for these bowls. They are taking over. lol I have no clue how long these take to make. I usually have 3 or 4 bowls going at once. I enjoy the challenge. I have a full time job. I do this for relaxation. I buy rough cut lumber for very reasonable prices. Maybe someday, when I retire, I will view it as a business. But for now, it's just plain fun.
