Altitude Engineering - Power Nail Pulller Attachment for a Hammer Drill
Students: Brady Adams, Longmont, CO, Zachary Frame, Rock Springs , WY, Yuma , CO, and
Advisor: Dr. Dennis Coon
In September 2007 Frontier Barnwood of Laramie, Wyoming, contracted Altitude Engineering to design and fabricate a power nail remover. A prior version of a power nail puller was designed and fabricated by Simple Solutions Engineering (SSE) during the fall of 2006 and the spring of 2007. However, issues remained to be addressed with the SSE design. These issues included binding and manual manipulation of the extraction teeth during an extraction cycle, over torque on the power screw, and material failures on a guide rod. Altitude Engineering inherited specific design specifications from the SSE project: nails to be removed range from 8d to 60d, the cycle time should be 15 seconds or less to extract a nail, the target weight is 10 pounds or less including the hammer drill, and an extraction should cause minimal damage to the wood. In addition the sponsor wished to use the DeWalt hammer drill purchased for the SSE project
The Altitude Engineering retained the basic power screw design of the SSE project but designed a significantly smaller support frame and a radically different pulling head. The Altitude Engineering pulling head teeth drill into the wood while at the same time close around the nail head. The power nail puller attachment was fabricated in the University of Wyoming
