Greetings all,
Could use a little help. I'm tasked with drilling 3/8-16 holes every 8" in a 10' x 1-1/2" diameter shaft. I will be holding the shaft on a mill table 40" long. The shaft will have to be moved about every 4 holes. How can I keep it on center and maintain a +/- .030 tolerance on the holes. I can use mill vises or v-blocks with clamps. My mill does have a DRO. I do have a lift cart to support the shaft when not clamped to the mill. Material is TGP shaft.
Looking for some ideas on how other folks would do this. I don't mind purchasing more vises or v-blocks if necessary. Hate to have to indicate each hole. Would like to be able to set up and use my DRO to stay on the 8" BTW centers.
Thanks in advance for help.
