The base is drawn out below. Sizes
are approximate and can be adjusted, but this is the size of the actual
one in the picture. Use 2" Square Tubing for the Base and Post, 1" or 1
1/2 " flat bar for the side supports, and 1 1/4" or 1 1/2" angle iron for
the third support arm. The pipe on the top is a 2" inside diameter pipe
with a 9/16 nut welded over a hole drilled in the pipe. The bolt is then
used to lock the car in postion as it pivots. A 12 foot 1 3/4 " outside
diameter pipe will be run through the middle of the car and sits inside
the pipe on the post. |
