I have an aprox. 16" 3 jaw chuck that has independently adjustable jaws that are also moved by a scroll in the convensional fasion.
I thought it would be worth the time to make a back plate for it to mount permanetly on my old flat belt drive 19" lathe. Are there any disadvanteges to it. It seems it has the best qualities of both a 3 jaw and a 4 jaw chuck. How come I don't see more of thease? It is a bit big for most work but I could always chuck up a smaller 3 jaw in it and dial it it in for most of the smaller work.
It dosent'have to be supper accurate on this old lathe. It gets used for things that don't require super accuracy. I have an old Monarch for when I'm trying for accuracy.
Comments on this style of chuck...?
