I learned something today LOL.

well your not good if you bored to 4.165 you should be at 4.163 or less you need to hone the finale size to 4.165 . you could use a good chewing out but i will not do that only to say you should allways verify that setup mics for boring bar interface with all mics used threw out the job before you start the job .this machine stuff is not like baking cookies
