A movable machine, for example a saw, has a light construction using composite materials such as fiber reinforced resins and a closed cell foam. The saw may have a housing (350) formed from multiple skins (384, 388) of the composite materials in which in the closed cell foam (356, 358, 360). Metallic inserts (372, 374) may be used to bond to either or both of the foam and the composite skin to accept working components. A saw is also described which uses gears sharing the same support element. |
