Re: Three Jaw Chuck / Spindle Bore Opening

You can bore the small 3-inch 3-jaw chuck out to 0.760 inches very easily. A better option is to purchase the 4-inch 3-jaw chuck?from Little Machine Shop.

Recently have started to use my little ole lathe. My machining background stems from “repair” as opposed to “fabricating” and so one of the first things I did was acquire a 4-jaw chuck.
After having the lathe for near 5 years now, I discovered the bore of the 3-jaw chuck is smaller than the lathe spindle opening.
I did not have a reason to notice this discrepancy before because I hardly ever used the 3-jaw chuck until lately for some repetitive work.

Is this something we just have to accept as an attribute of the machine, or is there a three jaw chuck available with a bore opening as large as the spindle opening?
