[QUOTE="birdiemc, post: 1594109, member: 29632"] I have thoroughly read and re read the information in this entire thread. I also received some PM coaching from Dusty which was very helpful. I opted to try things out on my lathe, instead of purchasing expensive dedicated equipment. I followed Dusty's advice and took the expander out of my sizing die and measured how much my neck was being worked, surprisingly it was not that much. I then turned down a mandrel the exact size of my expander, which took a couple of tries. I ground a tool with the proper angle to allow me to just kiss the shoulder and I set my depth of cut to try and leave about 20% untouched. I still have not purchased a tubing micrometer to be able to measure neck thickness and concentricity, but by taking such a light cut and leaving a portion of the neck untouched I am comfortable with the process. Measuring with a .001 dial indicator I have less that .001 run out on my necks after turning indicating less than .001 variance in thickness. It has been fun, and I'm able to crank them out surprisingly quickly. Still havent had an opportunity to shoot and see what difference it all makes, but hopefully this week work and weather will cooperate. Been waiting on a new beam scale to arrive too. But just wanted to thank everybody who offered up so much useful advice.[ATTACH=full]126210[/ATTACH] [/QUOTE]
