Step 4 Prepare the rods

Cut each 36” threaded rod in two; now you have four 18” rods.
Round off the cut ends with a file.
Check the threads of the cut ends with a nut.
   (To clean the threads, you may have to apply the nut onto the opposite end,
   then run it all the way up and off of the newly cut end.)
Mark each rod at 1” from each end.
Cut four 16” lengths of the Tygon tubing.
Slip the tubing over each rod.
Use a 1” scrap of tubing to protect the exposed threads in the bending process.
Bend one end of each rod at the mark to about 20° UP from straight.
   (Slip the short tubing piece over the end before clamping it in the vise or pliers.)
   (Keep the outer ¾” of the rod as straight as possible.)
Bend the unbent end of each rod, at the mark, to about 20° DOWN from straight.
   (Bend it in the opposite direction from the first bend!)
   (Keep the outer ¾” of the rod as straight as possible.)
Thread two bolts onto each end of the rods.
   (Each pair of bolts will be locked into position; the exact positions
   will be determined later.)
