Well I finally completed my lathe, now just ironing out the small glitches in the test phases. It is powered by a 1 hp leeson motor, and the main support is 6" x 6" H beam with 1/4 plate welded on both sides. The bottom supports are 3/8" thick 3" x 3" angle. low speed is around 300 rpm. I had put a large unbalanced blank on it last night and it is very stable with no vibration or movement. I would have to thank my father in-law for the use of his welder. Also after I told him my heavy duty lathe was almost completed he dropped of the wood in the other pictures. I may have exaggerated the capabilities of the lathe to him.
Thanks to everyone here for the help with the speed reduction questions I had ...couldn't have done it with out you.
