The evolution of the Ecomass weighting system was an easy concept with a complex geometric solution that we did not have. Dan began work on this concept with another engineer, David Cersley. David provided the blueprints, Dan the Solidworks modeling and Jeff the background golfing acumen. I was strictly a referee, albeit a strict, opinionated and passionate one.
David was Jeff’s Research and Development Director. A mechanical engineer by trade and like Dan Tagtow a tri-athlete for leisure, he provided a valuable interface between Jeff Sheets Golf, LRDC and Innovate Engineering. I had two tri-athletes on my team! Perhaps I should have been designing a road bike or running shoe but to my advantage both possessed the skills and qualities you would expect from such a competitor; intense, driven, paced, always knowing exactly where they were going and how to most efficiently get there.
Their were four weighting modifications in the first two months alone, followed by twenty CAD (computer aided design) models to create the geometry of one club. Was it was worth it? The first SLA (3D printed) version of our club answered that question, a polymer stereo lithography model accurate to less than 1%. A drawing is one thing but holding a model in your hand connotes a whole new understanding of form and function.
Stereo Lithography, or as it was commonly known SLA, is one of several types of additive manufacturing used in modeling and prototype work. 3D printing is the slang for this and represents all techniques for this additive process. SLA is the result of heating and hardening a liquid polymer by laser or UV light, in multiple layers, to create a 3D object.
This process provided a cornerstone to build on. It would literally be the foundation of our project, the source of all inspiration that followed. We were the architects.

“The strength or force gained by motion or by a series of events.”
Regaining momentum after a nine month hiatus was difficult at best. To break the boredom and monotony of the standard micro-management, of a newly acquired heart, was a challenge. Momentum is a fleeting force. We had it, we lost it and just like that the outcome to our iron development project was in jeopardy.
