Axle replacement

Hi there - looking for some advice.
I had to replace my rear axle last night.
The original has shoulders to support the cartridge bearings.
I've replaced this with a solid threaded bar.
The bearings sit inside the hub on a lip, so they can't move inwards. I've put enough nuts and spacers on the axle so that it sits tight between the dropouts. Hope the diagram explains this:

This arrangement seems to be working - it got me safely to work this morning. But will it work long term? Or I am heading for some spectacular bearing fail very soon? Thanks in advance

I guess the new alxe is a 10mm threaded one and there is a load of clearance between it and the bearing. Which is bad, but not terminal. I guess you also put lock nuts on the inside as a "lip" substitute. Which should be fine if they're in the right place. If you haven't, then you've probably got a lot of lateral load on the bearings so they will wear out faster. It is really casual, but I don't see why it wouldn't work ok for a bit. The only (really unlikely) way I can see you killing yourself is if you can get the bearing to disintegrate or walk out of the hub while you're traveling at speed.

Thanks mate - it's a bit of a bodge, but I now feel reassured that it will get me through to the weekend without killing me!
