NOT stupidity. It's called gaining experience. If you aren't making mistakes, you aren't learning much.Stupidity on my part.
Thanks, Brad. Always enjoy the creativity of "machinist-types."I drill them on the mill. I get them close with a pin gauge in the Chuck. Then I use a .0005 indicator to get the cavity centered. Center drill, drill under size, and ream the hole.
The bad one I didn’t use the indicator to get it truly centered and paid a price. Stupidity on my part.
When I do things right I get good results. Far easier on the mill than using a 4 jaw on the lathe.
