This is an intermediate level project. The original purpose of a Strong Arm shaper (in the late 1800s) was to make flat surfaces. The finished tool is a bench-top hand-operated shaper which can be set up using a left or right arm. It has a 4” stroke and a 4” traverse. Use the shaper to cut metal, wood or plastic. In addition to flat surfaces, you can make profiles, grooves, vees, champers, keyways and splines. The tool can also be set up with an automatic crossfeed.This castings set consists of nine castings – ten fully annealed iron and two aluminum – with drawings for machining and assembly.
