In Reply to: O.T. How to enlarge a large hole slightly? posted by Sherman in Idaho [108.162.245.23] on Wednesday, July 13, 2016 at 11:59:54 :
If you really have decided you need to enlarge the hole the best and only accurate way is to bore the hole. That means a Milling machine or lathe. Using sandpaper is not an accurate way of boring. It's a simple job for any machinist.
