<div dir="ltr" data-setdir="false">Alan,</div><div dir="ltr" data-setdir="false">Wes that is the start of a shoulder to grab it, good eye. Once the opposite side of the dome is machined I can not grab it in the jaws as you suggest. I have made an attachment that replaces my live centre, I guess its still kind of a live centre. It is a bearing assembly that pushes against the dome so it is sandwiched in place. That will hold it to machine the conical seat. I have done this in the past with a live centre but the bearings don't hold up long, so I built one with a large bearing. I had to come up with a step by step plan because if I machine in the wrong order I can get trapped with no way to hold it. I need a vacuum chuck!</div><div dir="ltr" data-setdir="false">Hank</div><div><br></div>
