Thanks Steve, I was thinking other end, was going to make a piece to chuck up in the mill and then slide into part. I guess what you said but up side down I think I'll go with what you suggest. I've been wanting to make a plate with a few holes machined into it that bolts to rotary table. Having something like that would give me more future clamping ability. I was planning on clamping part around bottom ring and also having a shaft (long bolt) up through center with plate to clamp from top also. Probably have to recess it so milling tools have clearance. Was wanting to use something around 3/16 for mill to get a small as possible inside radius on cuts. Plus the endmill I want to use has shaft same diameter as cutting blades. Can run right up along part without cutting too deep. Haven't had a mill crash in long time and don't want one anytime soon. At least this operation will not be 20min set up 1 min cutting time. And one of those parts that now I need to make more parts to cut the part!!!!
