We goofed on a part!
The hole was not tapped perpendicular. Jonathan Lewis (from Welding Tips & Tricks podcast) TIG filled the old tapped hole, then we re-machined the part on the Tormach 1100. Unfortunately we goofed again! Using the wrong edge to reference our Y put the hole off center. However, it was still a success: I now know that TIG can help fix machining mistakes!
