Perfect circles, ellipses or oblong circles can now be easily made on any irregular flat or round surface.
The Projector features a protractor with sliding rods and an adjustable lever to lock in the specified layout. A strong, 20-pound pull magnetic base holds the projector in position during layout. A durable web strap (included) holds the unit secure on non magnetic surface and can be used on either side of the vertical column.
The projector can also be used to lay out lateral intersections of different diameter pipes, or to project circles fom 1-1/2 to 18 in. diameter on flat surfaces intersecting at angles from 0 to 70 degrees from vertical. Attachments to develop larger diameter circles are available.
The Projector is equipped with a soapstone crayon and also works with chalk, pencil or steel scribe.
