I am wanting to build a lathe for turning larger projects (hollow wooden shells: up to 29" wide, about 30"-32" long, 1.5" thick all the way around). I have the motor, belts, drive wheels, etc... I just need to know what would be the best for mounting or housing a taper bearing. Would I absolutely need two of them (or more)? I am using a taper bearing because it is better for handling larger weight and stress.
