Reply to "Parallel Calibration Courses"

peteriegelRCMBB Founder

Because repaving destroyed my former course, I recently remeasured and reestablished the 1000 foot calibration course in front of my house. I added a parallel course to it, for use when somebody parks a car in an awkward place. The main course is 1 foot from the joint between the curb apron and the asphalt pavement. The second course is 8 feet from the joint – far enough out so that the riding path clears any parked cars.

When I put in the end nails on the main course, I did not pound them all the way in. I looped the end of a 50 foot tape to the nail and moved south until I was at a point 50 feet from the nail and 8 feet from the apron joint. I put in another nail here. Then I finished pounding in the other nail.

I did this at each end of the course. As a result the second calibration course is 49.5 feet offset from the main course.

A bicycle check detected no difference between the lengths of the two courses.
