Machinists,

I'm making some airgun parts that require me to hold a 1.250" and 1.225" diameter (round) part in my Logan (wards) lathe.

I have a 3 jaw that is good to about .003 so indicating is necessary every time since the front and back of the rod get turned and need to be concentric. It's a pain indicating each time I switch sides/ move it in and out of the jaws. I try not to remove it, but it happens and some models require machining between the turnings...soooo....

I also have an idea that requires threaded tenon be put on this 1.225" diameter piece at a slight angle. I was wondering if this is the right way to get the tenon square to the ways?

What do you think of this idea? Are these worth getting? Is there a better alternative?

Thanks all,
