I have two 5" Bison plain back chucks left over from a South Bend 9" lathe I used to own. One chuck is a four jaw and the other a 3 jaw scroll chuck. After hoisting the larger chucks on my newer PM1340GT, I am considering putting D1-4 back plates on them to use on smaller projects. Over the holiday, I was looking at pricing for the back plates which range from around $60 for Grizzly to over $200 for Bison.
My question is how important is the quality of the back plate to the accuracy of the chuck? If I can buy the cheaper back plates and I may try to put these back in service if they will be fairly accurate. I am sure the issue with quality is the same as everything else, but can I get the cheaper back plates and do some fitting and end up with an accurate set up? If It will take a $400+ investment to get there, then I would probably just save the money and continue to hoist the heavier chucks around for now.
Thanks for your help.
