ABSTRACT:
A precision radial arm saw includes a diamond saw blade for wet cutting a material. The radial arm saw is slidably coupled two shafts which extend in a horizontal plane above the cutting surface. The shafts are attached to a frame which is rotatably supported in a central rigid by a support beam. A lever arm is adjustable coupled to the support beam to ensure that the shafts remain horizontal as the radial arm saw is slid along them. The shafts are positioned sufficiently far apart that the saw is held in a stable position, without wobbling or tilting while cutting the material. The size of the material cut is precisely determined by using a spacer plate adjacent a precision set fence. Spacer bars may be placed between the spacer plate and the fence to provide precise cutting of specimens of different sizes.
