  • Core Drill Repair

    My friend Bryan is a Civil Engineer.
    He uses the core drill to drill and extract soil samples.
    Unfortunately he often encounters rocks during the drilling process.
    In this case three things can happen:
    1. The auger ingests the rock
    2. The auger pushes the rock into the wall of the bore hole.
    3. The blade of the auger gets bent.

    The auger that Bryan dropped off was the third case.
    The following pictures show my process to repair it:

    1. Bend blade of core drill
    2. Arbor that I made
    3. Last little gap
    4. Weld position with arbor installed and gap closed
    5. Core drill repaired
