In this video I use the Human Powered Cross-Country Ski Groomer to make a trail to ski on. This device is now called My Trail Groomer and it is sold at www.mytrailgroomer.com. Snow conditions vary widely. On a nice day I can groom a 2 Kilometer loop in 30 minutes and than ski a number of laps on it for exercise.
Human Powered Ski Groomer Dimensions
All measurements are in Inches (this was clearly designed in inches and uses inch dimensioned white UHMW Polyethylene
Main Surface 30 by 24 (30 wide) made out of 3/16 thick UHMW 2 holes at front corners for 2 tow ropes that run to the back of the operator. A lager oval hole at the front center is the carrying handle. The runners stick out 4 past the back edge of the main surface.
Ski Runners 12 inches long and trapezoidal in cross section. They are 1-9/16 thick. the top is 4 wide and the bottom is 2.5 wide the front is sharp like the bow of the boat. (They look more like boats than skis the bottoms are narrower than tops and sharp in the front.) The runners stick out behind the main surface by 4.
Weight Box is 6 by 6 by 30, but the sides of the box are rhomboid. When the main surface is flat on the floor the front and back wall of the box is leaning forward at 70 degrees. This makes the sides of the box a 6 by 6 rhomboid with 70 and 110 degree corners.
When you tow the device it rides in the snow like a water ski with a 20 degree nose up attitude. The box and the weights are then perpendicular to the ground. The snow is gradually compressed as all the weight is concentrated on the back edge and the heels of the runners that stick past the back edge.
This is assembled with 1-1/4 drywall screws driven into pilot holes.
