Hi all....
I've been having issues with a 4 jaw chuck... i can't seem to get anything to come close to dialed in. Grizzly replaced the chuck for me and admitted that it was defective. well i got the new one in and Im getting the same results.
The Jaws are not parallel to each other. so it only tightens down on the from teeth. I try to dial in a piece 2" round aluminum right in front of the jaws then go out 3 or 4 inches and its way off.
Here is a photo of the jaws. there is no gap at the front, the back has a .012 gap. this doesn't seem right. Am i expecting too much out of the chuck i would think that they should clamp down even. I think that it may work using a steady rest but the work I'm doing is too short.
Would a bison chuck look like this? I like my machine just a few bugs i gotta get worked out.
kinda hard to tell from the pic... but there is clear daylight on the back side.
