Year Three

HISTORY
The idea entered my head two years ago when I was skiing at White Face in NY with my wife, brother, and sister-in-law. I got off the chairlift and noticed that the tips of my Blizzard Titans were cracked. Having recently graduated from Grove City College with a BS in Mechanical Engineering, i quickly analyzed the situation and decided that it was an obvious design flaw. These happened to be my favorite skis of all time and I decided that the only way I could get a better ski was to build it myself. My Uncle Andrew further taunted my by telling me that I could not make skis, that would be functional at least.
It all started with the Goliath, which was renamed the version one (V1) when I modified the design for year two. The Goliath V1 would be best described as a light, "noodley", powder ski.
They were very light weight, made from a poplar and aspen mix, but with only a single layer of fiberglass they flexed like spaghetti. They were designed with an ABS (plastic) vertical sidewall which turned out to be very difficult to work with. The end look was pretty nice, but the sidewall design would be changed in year two. The Goliath V1 was a perfect powder ski, but couldn't handle the crud.
Year one had many trials, including, but not limited to:
  • Wavy/ convex base shape due to poor mold design.
  • Exploding ski press due to engineering miscalculation (this led to a trip to the ER and two stitches inside my mouth)
  • Peel off top sheets
  • ABS sidewalls
  • Edge tearout

In year two I created the Goliath V2. The Goliath V1 and V2 were similar, but V2 was much more technical and designed to correct all the flaws of year one. The V2 was a cap design (vs sidewall) built with two 3ft stainless steel rods and two 5ft aluminum rods in each core. I wanted to bring my brothers dream to life, which was to build metal into the skis. The V2 incorporated a rubber strip between the edge and the reinforcing fiber in order to prevent edge tearout. Additionally, I used a carbon/Kevlar fiber weave in place of fiberglass. The core was composed of maple and aspen and the core was thicker than year one. In short, this ski overcompensated for the "noodle" Goliath and the skiing experience was described as, "...It's like skiing a pair of barn doors." Needless to say, they crushed any crud in their path and provided an ultra-stable ride. They would be much better suited to a 240 lb man, not my 165 lb brother.
In year two I also created the Tomahawk, which had many of the design features as the Goliath V2, but was narrower and was designed to be an eastern mountain ski rather than a powder ski. I used the Tomahawk every time I went skiing and did my best to break them, but they were resilient. This ski, although stiff, worked well in all conditions and handled impact well.
YEAR THREE
This year I am creating a brand new ski, the Arlia, which has a length of 161cm and a maximium withd of 129mm; this ski is designed as a woman's ski with a hybrid rocker/camber design. I am sticking with the cap design, but will be using fiberglass in the core and won't be placing any metal inside the core. I am attempting to keep it simple.
In addition to the Arlia, I am overhauling the Goliath V1 and V2 designs with the Goliath Extreme Rocker (GXR), for lack of a better name. The ski is a full rocker design with a length of 181 cm, maximum width of 137mm, and the ability to crush powder.
