    Spline Alignment

    Hi everyone, I have a job where I am making a driveshaft with splines in the lathe, and the splines have to line up for correct drive-line phasing. I do not have a sub spindle, and cutting flat spots for references would likely off-balance the shaft. What other options do I have?

    New Chuck - Drawtube Modification

    Hi everyone. I recently got a new Royal ID chuck for our lathe. The 3 jaw power chuck we have uses an adapter plate on the A2-8 spindle mount, while the new chuck won't need that adapter.
