Finally got a lathe!

Well after trying to find a shop to machine my custom hubs without any luck (a couple members on here did offer their services) I decided to get my own lathe.

Here is my beautiful condition Atlas 12 x 36 lathe!

Nice to see you got your lathe !!
What area are you in ?
I went to school with Doug Dubois in Zurich.
Any relation ?
 
Currently close to Gatineau. Grew up in Prince Edward County in SouthEastern Ontario and spent the last 12 years in Quebec City.

No relation.
 
Sorry, I guess the Dubois name is common.
We rented an apartment for a week on Rue Couiliard in old Québec City a few years ago.
Careful with those hubs, are the bearings PressFit ?
Tapered roller or sealed ball angular contact ?
 
Congrats, for me that day was the start of life long journey of learning and the thrill of making stuff. I hope you have as much fun with it!

Bearings for the hub are timken tapered roller. I have them on hand so I can cut to fit. They don't need to be a press fit as the spindle nut will keep them in place. I'll go for snug but I don't want to be heating or hammering to get the races in there. I will probably green loctite them in just to be sure.

Measure and check again. Light cuts but wat h you do not work harden the seat material.
If you can . . . keep heat away from precision bearings.
When you are at the final assembly stage, snug up the lock nuts and then back them off a notch before you put in the cotter pins.
 
No cotter pin for the spindle nut on this build as the spindle is hollow and carries a stub axle through the center. Going to have to figure out another way to keep the spindle nut from backing off. That's a problem for future me haha.

Highway tractors n' trailers use an adjusting nut , a lock plate and an outer nut to lock it all down , a lot like older 4X4 pickup trucks when they had actual serviceable wheel bearings. The nuts are thin , they appear to be punched out of sheet stock and threaded to create an effective , low profile nut.

Sorry, I should have asked you for a photo of the assembly.

Now that you have a lathe, the $$$$ will being to flow as you keep adding tooling (and machines). Wait till your spouse finds out.

That is for certain, but, it's also a very good time to make much of your own tooling at this stage, it really helps you learn your new machine and it's capabilities, and you enhance it each time. An indicator stop would be a good first project.....
Congratulations on your new lathe, let your mind wander a little, and you'll be amazed at what you can do with just a lathe and some time.....

The truck rear axle style has tabs on the middle washer, that get bent to lock the outer nut in place, usually. A front axle has a very similar setup but the middle washer locks the inner nut in place, the outside nut is just a jam nut. There’s usually a keyway for the middle washer, cut into the spindle

It must have to do with bearing preload but I don’t actually know why. Maybe @dfloen knows?

Edit: on the older stuff, before unit bearing front axles and such

It’s to lock in the bearing adjustment , there isn’t any preload on a wheel bearing
