PROJECTS: ALUMINUM LEVI TATOR
1. MAKE THE STAND
Time: An Afternoon Complexity: Easy
Cut the 2× 4 into three 1' lengths. Drill a ¾" hole centered through
one of them.
Attach the ¾" drilled wood piece crosswise over the other
2 pieces to make an “H” shape. First, mark and drill two Y"
holes staggered at each end of the center piece using a countersink (see figure at right). Next, with an awl or thin pencil, mark
pilot hole locations on the middles of the other pieces through
the countersunk holes. Drill E" pilot holes, line them up with the
holes on the center piece, and screw the stand together with four
2½" #8 screws.
Attach the 2× 4 boards
together with four 2½"
#8 wood screws
Drill ¾" hole in
center of top board
2. WIND THE COIL
2a. Cut the plywood or PCB material into two 4" squares and drill
a ¾" hole in the center of each.
2b. Jam the 2'– 3' metal rod through the hole in the stand so it
protrudes 1" from the bottom, and slide one of the 4" squares
down the rod from the top, resting it on the stand (about 3" from
the end of the rod). Use epoxy to cement the square in place on
the rod — then, using your wire spool for spacing and temporary
support, slide the second 4" square onto the rod and epoxy it in
place, about 2½" up from the first. Let the epoxy cure.
