Centering on a 4 Jaw Chuck using Marking Block

Centering on a Jaw Chuck using Marking Block/Surface Gauge is one skill which a good turner needs to master in order to do precise jobs on the Lathe. 



It is a bit tricky at the beginning but as one gains experience & practice, centering becomes fun & a lot of machinists take pride in their centering skills (including myself :P).



I have tried to demonstrate how one can use a Marking Block/Surface Gauge for Centering on a 4 Jaw Chuck. Would love feedback on the video, if it was helpful or not. I will be posting a video on dialing a job on a lathe, soon.
