Hi,
On my 10-inch chuck I've got two set of hard (grip) jaws for various OD spans, but I can't go below 18mm OD. This is driven by the width of the jaws, which is 40mm in my case.
Is anyone here aware of commercially available hard jaws that are more narrow towards the chuck center end? - they would then in theory be able to grip onto lesser OD's.
I have played with the thought of using a 3-jaw drill chuck of sorts and gripping this with my jaws, but it sounds like an accident waiting to happen.
It's a shame that collet chucks require removal of jaw chuck - for my work flow this would be wildly inconvenient since we have usually have one or two off's and no series.
I thought about using soft jaws and drilling a hole in the center, but would prefer a harder and serrated jaw that will not slip so easily once I stray away from the drilled hole size. I don't want to have loads of softjaws drilled for everything between 17 and 10 mm if you get my drift. I already have 19 sets of machined soft jaws on my shelf (where I use most of them regularly btw).
Thanks for all ideas, I hope there's an easy fix out there!
