Equipment Development

Foro Drill
IDDO continued to procure drill components during the quarter as planned, including a slip ring and a winch frame assembly. Design of the cable was finalized and the cable subsequently ordered in early August. The control box layout was reviewed, the mechanical design of the box was finalized, and custom aluminum cases and faceplates were procured.

Equipment Development

Foro Drill
IDDO procured several major drill components during the quarter as planned, including a Lebus core for the winch drum, a winch motor, a winch motor gearbox, a motor VFD and a pre-fabricated cable assembly for the winch control loop. IDDO finalized the design and ordered a new four-conductor cable in early August. All components for testing of the winch control loop were received. IDDO completed a dimensional report on the winch Lebus core. This core was sent to Innovative Machine Specialists for final assembly, including heat treatment, anodizing and machining. The control box layout was reviewed, and IDDO began finalizing the mechanical design of the box. http://icedrill.org/equipment/foro.shtml

Beneficial Design Upgrades Continue for 4-Inch 'Foro' Drill

During the Second Quarter, IDDO completed the preliminary design of the new 'Foro' Drill System to upgrade the popular, yet aging, 4-Inch Drill equipment. IDDO engineers have utilized feedback from 4-Inch Drill operators to make this new system lighter, more robust, more easily controlled, and more user-friendly. The sonde design is based on that of IDDO's Intermediate Depth Drill (IDD) and the current 4-Inch Drill designs, with certain components being interchangeable with the IDD, including the anti-torque section, motor section, and the cutter head. The designs for the 'Foro' Drill sled, winch, cable, and control system are brand new designs, and the tower is a modified and improved version of the current 4-Inch Drill tower design. The new sled, winch and tower assembly alone offer a 40% weight savings over the current 4-Inch Drill components. In addition, upgrading the control system to include only one comprehensive control/readout box, as opposed to the two separate boxes used by the 4-Inch Drill, will offer an additional 30% weight savings in this area. In March 2015, IDDO circulated a 'Name That Drill' Doodle poll to encourage IDPO and IDDO team members to vote on a name for the new components, so that distinguishing between the old and new equipment would be more straightforward. The name 'Foro' was selected, and is Latin for "to make a hole, pierce or to bore". On the last day of the Second Quarter, April 30th, IDDO held a Preliminary Design Review where the engineers presented the new system design and future plans for the 'Foro' Drill.

The major design upgrades for the 'Foro' Drill include:

  1. Redesign tower and winch to be lighter/smaller
    • 5.7 mm diameter steel electromechanical winch cable, same as used on the IDD Drill (current 4-Inch Drill cable is 13mm in diameter)
    • New cable weight is 13.1kg/100 m (current 4-Inch Drill cable weight is 17.1kg/100 m)
  2. Upgrades for wet conditions
    • New sealed motor section – submersible in drilling fluid or water (current 4-Inch Drill is not submersible)
  3. Upgraded control system
    • Drill and winch motors will be able to be run simultaneously
    • Off-the-shelf motor controllers
    • Reduced weight, compared to the existing 4-InchDrill control boxes
