This Instructable will show several modifications I made to our basic NordicTrack ski machine and give enough information that the reader could make similar modifications to his or her machine.
Step 1: Add Detachable Wheels
I experimented with using the ski machine while the wheels are in place and after the springs had been released so the skis can move normally. But, the ski machine can move forward and backward a little on the wheels. That creates havoc with the protective floor pads at the rear of the machine. Earlier I found a broken weld on the rear support, but it was probably unrelated to putting wheels under the front of the machine.
Step 2: Support Foot
Step 3: Secure the Upright Column for Storage
There is an electrical cord inside the main post. Sometimes this cord blocks the hole for the bolt and I need to wiggle it out of the way with the end of the bolt.
Step 4: Make the Bolt Easy to Use
The head of the bolt does not need to turn 360 degrees as long as the nut can. But, there is a restriction that would block the nut if the lever on it were as long as the lever on the bolthead. I tighten the nut finger tight. Then I tighten the handle on the bolthead.
Step 5: Tray for an Audio Player
Step 6: Cord Rests
Step 7: Exercise Computer
Our eBay computer came without any connecting cords. See the second photo. The electrical line that picks up pulses from a reed switch operated by a magnet on the flywheel is a simple 1/8 inch mono audio cable.
Step 8: Heart Monitor
If you are using a ski machine for weight loss, etc. and heart rate is important, your breathing rate can be used well, and without a monitoring device. A good target heart rate for endurance exercises, like bicycling, that can lead to weight loss is about 70 to 75 percent of one's theoretical maximum heart rate. Co-incidentally, when I used a heart rate monitor on my bicycle, I found that rate of exertion happens at about the point at which you need to open your mouth to breathe while exercising, or just below it.
A better heart rate monitor would be one that involves a strap around the skin on your chest with a readout you can see while exercising. Various companies make such devices in various price ranges.
Step 9: An Irritation
Step 10: Normal Wear
Step 11: Something Else
Step 12: Steps for Using or Storing Our Ski Machine
- Lay the machine down so it is in its normal position on the floor.
- Pull the spring hooks from the frame.
- Lift the front of the machine and remove the wheels and their axle.
- Loosen and remove the retaining bolt on the main post.
- Raise the main post and secure it with the retaining bolt.
- Raise the arm with the drum.
- Raise the arm with the abdomen pads.
- Lower the drum arm.
- Lower the abdomen pads arm.
- Remove the retaining bolt and lower the main post.
- Secure the main post in the storage position with the retaining bolt.
- Raise the front of the ski machine and slide the axle into place. Lower the ski machine onto the axle.
- Push the front ends of the skis back and attach the spring hooks.
- Lift the back of the ski machine from the floor and roll it to the closet.
