I bought a 10" Chinese 4-Jaw independent chuck thinking I could use it on my 17x31" Grizzly. I bought it at a yard sale, new in crate, so I had to make a quick decision and bought cause the price was right. Once I got home and checked my manual, it does not recommend using any chucks larger than 6". I've had time to soak it in and was thinking why wouldn't it be good? It weights 50 pounds and my spindle bearings are roller type. The chuck mount is part of the spindle with only three holes for mounting chucks, back plates, face plates etc. They use these same type bearings in autos and they support 3000 lb front ends so why couldn't it support 50 lbs? Crashing the tool post would really be hazardous to the gears as well as maybe starting the chuck spinning. Does anyone else use a larger than recommended chuck on their lathe? What ya think?
