ABSTRACT:
A portable lathe for performing machining operations on a stationary member. The lathe is of split construction permitting the lathe to be mounted on the member from the side of the member. Each of the end housings have removable sections that provide a side entrance to the bores of the housings. Parallel guide ways connect the end housings and support a moveable carriage assembly. The carriage assembly rotatably supports a rotating tool holder and carrier on a unique roller arrangement simplifying construction. The carriage assembly has removable support struts and the carrier and tool holder ring are splitable which provides a side entrance to the bore of the carriage assembly. The lathe is secured and aligned to the member to be machined by adjustable jaws provided on the end housings. Twin leadscrews provide motion to the carriage assembly and reduce the twisting and deflection experienced with a single leadscrew.
