I use the hot wire tools, I don't like paint,plaster, glue, or any other liquid mess. And I don't like taking all day to do something. This scene what you see is about 1/2 of it, took 30 days from tear out, to finish. Carved and painted in the garage then moved to location in three large sections. the whole thing is about 6 x 12 feet. that curve is 120" Dia. And a 2% grade.
