How to process back plate to guarantee Chuck's T.I.R?

The fully-machined chuck back plates can be mounted onto 5"  Jaw zero-set fine adjustment self-centering scroll chucks lathe chuck (p/n 202-6555, 202-6556). All back plates have 0.04" allowance, please measure the size of Chuck's D1 before process your back plates. The size of back plates's D1 should be a little bit smaller than the size of Chuck's D1. Because the gap between back plate and chuck is smaller, chuck's TIR is better. No gap is the best. 

You would not need to drill any mounting holes but you will need to turn the shoulder down .040" to match the back of the lathe chuck to make the chuck & back plate more concentric with the lathe spindle. When turning the shoulder of the backing plate, ONLY TURN THE SHOULDER OF THE BACKING PLATE WHEN ATTACHED TO THE LATHE SPINDLE. If you use a chuck to clamp the backing plate and then turn it, the backing plate will not be true to the lathe spindle and will have more runout than specified when the chuck and back plate are put together. 

Product includes

• 3 pcs of studs for mounting into the cam lock on lathe spindle
