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.
