any one use a set of trailer hubs and bearings set up so hubs are fixed in place,and steel shaft turns by 1/2 hp motor ?

Sure. Almost any lawn tractor uses this set up. Rear wheels of a tractor are fixed to shaft thru a key that keeps it all together. Engine keeps the tranny going that keeps the diff going and that powers the shaft that keeps the wheels go around and around.:wink:

Greenwing,
Not exactly sure what you are trying to do but as Jack said that is pretty much how many mowers are run. How are you applying the power from the motor to the shaft, via a fixed pulley, direct drive or some other way. What are you trying to do over all as you might use pillow block bearings to support the axle shaft just in borad of the wheel hubs.

Check the max rpm allowable of the tapered roller bearing before getting into this too far. You may or may not need a serious rpm reduction.

its for a concrete lathe i saw on you tube,the example made used cheaper flange bearings,the shaft will have a key cut for a pulley,the other end needs attachment to a chuck,and some way to preload the bearings since there will be no threads to use castle nut.

I figured that you gonna build some kind of lathe or a conveyor. Don't waste your time on this one! Garbage in - garbage out. If you need a lathe...get yourself a real lathe.

When you say "lathe" I'm thinking precision. You are willing to spent all that time building frame, pouring concrete, somehow encrusting two perfectly good bearings into concrete slab, modifying axle, installing some sort of gear reduction box; etc, etc...and at the end you gonna be very disappointed with its performance.

I meant no disrespect in previous reply and wish you best of luck...what I'm saying: maybe you should reconsider?

Have you seen YouTube concrete lathe? He's still getting it tuned up,the bearings he used are suspect,and more bugs to kill.for me ,i never used a lathe, but life is getting shorter,and the few jobs I would do .don't justify big cash outlay.dont have to be perfect,but it has to run at low speed for saftey,it is not for production just one offs,for me ,here in ct machine tooling etc is sold at basement clearing prices at local flea mkt,not whole machines though ,still premium prices.so for 200 bucs est.I'm ok with it.thanks for good advice.your absolutely right.?

I see what you're saying. I'm skeptical about your budget. May I suggest for light woodworking, polishing things; etc...this "bad boy" for about $220.

But if you're willing to invest about $600...you could be sailing with this beast!!!

Greenwing,

I see what you are trying to do and trust me, I have been there, done that. Do you have a drill press by any chance? I have turned a few small items both in wood and metal using my drill press as a "vertical lathe". Basically I needed to reduce the outside diameter of the object or cut grooves in them so I chucked up the piece and turned on the drill press set at the slowest speed and went at the part with rasps, files and sand paper. I never had to support the bottom end of the pieces as they were fairly short but I think you could add a "tail stock" to the drill press table if needed.

Yes I have a 15" floor d.p.tried milling with a piece of aluminum plate few years ago to make lead mold for L shape decoy weights,wow do not try it quill dropped out many times! That's verticle only.

Cast in concrete by a person with no understanding of materials science
Getting that set up true would be a very difficult task.
Keeping it that way impossible.
Concrete changes dimensions over time. it is not stable.
The head stock will crumble from the vibrations caused by turning anything that is not perfectly round.
It is an idiot idea that could have the operator spending a long holiday in a hospital.
The end product would be lucky if it was as accurate as a junk Chinese lathe from HF .
The USA is awash with good used lathes.
