This chuck centers excellent and furthermore the already mounted back flange has the same fitting as my Swedish built BLOMQVIST BSN600 benchtop lathe main spindle. I bought this far to large chuck as I sometimes have use for the large capacity and already have used it, see photo. I am very satisfied with this purchase.
