Some Answers for questions
Doug, I use my Oneway Talon Scroll Chuck for most of my Bowl Turning. I usually use the center screw that came with the chuck, along with the tailstock and live center to get the rough blank round. I then turn a spigot on the end that I want to be the bottom of the bowl, then chuck it up in the Talon Chuck, and have at it. I have been experimenting with parting the bowl from the blank, and I have done it several ways. If you plan ahead, you can leave some waste on the bottom of the bowl blank, near the chuck, and just part it off carefully when you have finished turning and sanding the bowl. I have also use a reverse chuck method (I think that is what they call it, it's what I call it anyway?) to finish the foot, or bottom of the bowl. I turned a section of Oak that has about a 3" diameter end on it, tapering down to resemble a morse taper that will fit my lathe. I can insert this piece of Oak in the lathe drive, tap it in lightly, and chuck the bowl up with the bottom of the inside of the bowl resting on the Oak thingy, and the tailstock with live center supporting the bottom of the bowl. I glued a piece of dense rubber-like gasket material to the Oak Thingy to help grip the bowl interior bottom. This takes some fooling with to get the bowl centered, but as long as it is close, you can then finish the bottom. I part off the tenon, or spigot, as close to the live center as I can, then just cut a small slice with a thin Skew to allow the small tenon that is left to snap off. I have used a small fine saw to cut off the tenon also, but the method I just described works well also. I will probably eventually get the Jumbo Jaws for the chuck to allow me to hold the bowl by the top rim, but I may not either, as I have had good results using the methods above. I am just a beginner, but if you need any advice or suggestions, just holler, I will gladly help you all I can! :D
(I hope some of this made sense?) ;)
