Abstract: My interest was aroused by the lack of any power tool to help the electrical contractor cutting rectangular holes through walls for his wall boxes for switches and receptacles. I started making a model in 1992 only to find out there was no parameters to follow for the specifications the thrust needed. To push four saw blades were one problem to solve. The fact that the unit would require a rigid attachment to the wall was another problem to solve. The small rectangular hole gave little room to work. The last problem to solve was about 12 inches of simultaneously sawing. By Thanksgiving time of 1996 my fourth model was finished. I had the surprise to discover that I was able to saw a rectangular hole of two inches by four inches in 1/2 inch plasterboard in about ten seconds and in plywood, less than one minute|This could be an excellent item for the mobile home builder to cut the holes in the walls. He would welcome this saw.
