Keeping shaft bearing supports true...

Yes...I erred in referring to the bearings I have...they are just typical roller bearings where the outer race has a flange...the bearings slip into a bored hole in the 3/16 brackets...the flange holds it in place...

Well that's not a bearing style I would use on that project. Not using self aligning cylindrical ball bearings is complicating your project and probably compromising its durability.

I agree self centering bearings would make it less tedious fabricating...but the bearings and brackets I am using are pretty standard for the application...
...Below is a picture of a kit that is similar to what I am doing...using the same type of bearings...The flat bottomed washer looking pieces/brackets get welded to a frame or plate and are what the bearings fit into...

I think your best chance to keep everything square is to c clamp a piece of heavy angle iron to the base plate and upright piece to hold it square while you weld. I would also clamp the base plate to a thicker plate so it doesn't warp toward the welds if you can.

About all that bearing style is 'standard' for is low speed, low power, low use applications. I guess I can't help you more because of the obvious philosophical differences we have about how the job should be done. Good Luck.

I'm always open to suggestion...It's not so much "my way" of what I'm doing...it's just what I've researched and learned that a lot of people doing the same thing and use this type of hardware...it's typical...

This is just a little jack shaft for a mini bike to reduce the gearing...it's not going to be used for industrial/commercial purposes...
There are a lot of ways this project could be done (see link below)...I am just trying to keep it as simple and easy without a ton of hours in the process...
I do appreciate all replies...
