A lathe having a bed is supported on two legs. In one embodiment, the bed is hollow and has an inner portion into which a weight enhancing material may be inserted. The bed may include two tubular members separated by spacers. The tubular members may ha ve cross--sections that increase stiffness. In another embodiment, the bed is attached to a support assembly that includes first and second hollow legs, which may also contain weight-enhancing ballast. The first leg may be attached to a first hollow foot and the second leg may be attached to a second hollow foot. A stabilizer bar may be inserted in each foot for increased stability. Pairs of wheel assemblies may be attached to the first and second feet. In yet another embodiment, the lathe includes a headstock having a housing slidable along the bed. The housing encloses a motor that drives a shaft having two spindle ends protruding from the housing.</SD OAB> |
