Tapping

Last week in the workshop we covered tapping and removing a broken stud. We started by drilling a hole into a piece of steel, then we tapped and and screwed a bolt into it, we then cut the head of the bolt to simulate a broken stud. We began by drilling through the broken stud right the way through, then used an EZ out to remove the broken stud. After this was complete we covered repairing a thread. We drilled out the hole and re-tapped it, we then used a Heli-coil to repair the thread.
