I finally have a 4 jaw chuck on my Atlas lathe. There was a small back plate included with the lathe when I bought it. I machined it to fit the register diameter of the chuck and had to file the 3 holes in the back to get the studs to fit.
The chuck is off of my mini-lathe, it's only 5 inches. Eventually I'd like an 8 inch chuck, but this will work for now.![666daba7f566970e4060485fdf1ebab8.jpg 666daba7f566970e4060485fdf1ebab8.jpg](https://www.hobby-machinist.com/data/attachments/142/142349-3e501f48a7078e53f6eee98dc6358720.jpg)
