You too can machine a very simple, low-cost rotary tailstock chuck for your lathe with this OneSimpleTrick(tm). Spoiler alert, there's no trick, this device really IS simple to make.
Holding small diameter workpieces in a lathe often needs a tailstock-mounted rotating chuck. They are a lot of work to make and are not exactly cheap to buy. If you already have a rotating tailstock centre, this is a nice easy project to hold long and thin parts to help control chatter, singing and deflection. I'll be using it to make multiple circlip grooves at very precise spacings, but I've also used it to cut long single-point threads in 3 mm or 1/8" rod. It only has two parts plus some grubscrews and was a fun little project on a rainy afternoon to make my lathe even more useful than it already is.
Expect to see it appear in some upcoming machining videos!
