Project Steps

Make the sensor holders

One is for the main frame, and one goes in the primary arms.

Weld the rebar to the threaded rod at a right angle.

Protect the threads on the threaded rod by welding. (A small pipe works well)

Thread a nut onto it.

Make the Thin Cylinder Supports

Weld the 1″ pipe to the 3″ U-channel, in the center. 4-8 good tacks is sufficient.

Make (2) 6″ long 3/4″ bolts, by using a nut and 6.25″ of threaded rod. See Making Bolts.

Make the Magnet Holder

Weld the flatbar to the 1.25″ piece of threaded rod.

Protect the threads.

Make sure they are perfectly paralell!

Thread a nut onto the threaded rod.
