I don't think there's any way to disguise the vertical cut unless you're making a bowl from a slab cut across the trunk so that the end grain runs in an up and down direction. And that would mean all the ring glue-ups were end grain to end grain, and I'm not sure how well that would work.<br /><br />That Lee Valley chuck sounds interesting, but you still have the issue of drilling at an angle with a very short bit. I find the small chuck for the Dremel works fine for me, along with my primitive, but accurate, angle gauges. The standard chuck of my Delta drill press goes down well below 1/16", but the wire sized bits are so short that they would just about disappear. If I'm careful, start the hole with an awl, and ramp the drilling speed way down, I can get a good hole. Most of the time!<br /><br />Thanks for writing!Carolehttps://www.blogger.com/profile/08324249834681506315noreply@blogger.comtag:blogger.com,1999:blog-1908730744821622284.post-50163432324336691902017-07-30T14:26:59.615-07:002017-07-30T14:26:59.615-07:00Carole, thank you for showing the results of this ...Carole, thank you for showing the results of this cut instead of the entry hole! No short-cuts on the round bowls but I wonder if this cut could be hidden in the end grain of a square bowl? <br /><br />Speaking of blade entry holes, Lee Valley recently sent out an email promoting their limited quantity hollow-arbor chuck (http://www.leevalley.com/us/Wood/page.aspx?p=75987&cat=1,180,42334&ap=1). They claim to work down to a 0.3mm (#80) drill bit.<br /><br />I just used this arbor with a #65 bit through 4/4 walnut and got the cleanest hole I have made in a while. Highly recommended and I hope they keep selling it.Jaredhttps://www.blogger.com/profile/01168912511517878158noreply@blogger.com
