Big Compass

Ever need to draw a BIG circle, well here is the tool. With thers printed parts and a 3' x 1/2" dowal you can draw up to a 6' circle
for the point used a piece of 3/32 tungsten but a nail should work also.
there is a small hole in print where point goes but that need to be drilled out to match the point you use
bolt holes are 1/4 20
