ER32 collet chuck on my 7x12 mini lathe. Fast, repeatable concentricity that can’t be beat! Great for small parts up to ~3/4″ (20mm is the largest collet size).

Apologies for the shaky-cam (shooting handheld, obviously) and froggy voice (sick with a very sore throat). v_v

ER32 collet chuck for my 7x12 mini lathe. Littlemachineshop.com carries these for $200. Ebay has them for $55 plus shipping. No-brainer. 

Annoyingly, there were no holes in the perimeter of the chuck for a pin/spanner wrench to hold it still and prevent it from rotating while tightening the collet, so I had to drill three of my own on the mill.
