How do I mount or house a Taper Bearing?

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.

Another idea: I once took apart a gear reducer unit that had a dual output shaft, The output shaft had taper bearings on each end,
The output shaft was driven by a worm gear on a shaft which was perpendicular to the output shaft.If the worm gear shaft was removed ,you would then have a free spinning output shaft, and could mount a pulley on one end and screw plate or chuck on the other end to hold the work piece.

I did some looking into these gear reducers with dual output shafts and shopped around and found this to be very helpful, thank you! It is definitely turning into a larger hassle than what it is worth for building from scratch as others have mentioned and I thank you all! RavensCraft, the dual output shaft is very ideal and would seem to work perfectly in the manner as you suggested with mounting a pulley on one end and the faceplate on the other after removing the perpendicular gear shaft.

What machine shop access have you got ? I'd be tempted to buy big "plummer blocks" for a simple wood lathe, rather than the hassle of building a full machine bearing.

I do not have access to a machine shop. I have looked into pillow and plummer blocks, seems like the best bet so far. Thank you very much!

+1 much easier.

Warning! I am not a mechanical engineer but I think your front bearing should be tapered to withstand the thrust generated by turning and the rear can be a straight bearing to support the back of the shaft.

Many old lathes had simple white metal bearings and apart from needing adjusting on occasion worked fine.

has several sets of old plans for lathes.

Yes, But even the Myford bearings are tapered at the front

You could try something like a trailer spindle and hub.
