Yesterday the 1980s-era Burley trailer got re-tired then the left wheel bearings went. I wrote in a post, I'd switch to the damaged, 1990s-era, Burley trailer; instead, I've tried hard to fix the 1980s Burley. I said tried, not succeeded.
Done before bed; involved winding heavy coated steel wire around the axle, spring-like, to fill up the gap left by the bearing bits. Made it one block the next morning, before the patient rejected the transplant.
Used an aluminium handlebar, which had the diameter, and wall thickness to both fit over the axle end -- which looked a lot like the end on a carriage bolt -- and inside the wheel hub. It did not fit over two bearing sleeves, still on the axle, so I cut three, roughly, half-inch pieces off the handlebar, and cut one side of each lengthwise, so I could open up the diameter, slip each of them on the axle between the bearing sleeves, and close them back down to their original diameter.

The wheel fit on the axle, but was still unaccountably wobbly. I took about two inches of handlebar, and fit it in over the axle end; it went in about three-quarters of an inch before hitting the first bearing sleeve -- this took all the wobble out of the wheel, but how to fix it in place? Using a heavy chisel, I endeavoured to crimp the tube behind the axle's "bolt head" end.

Fix number two worked for most of the afternoon, but I noticed the wheel was still able to slowly "unscrew" itself from the axle, so I put a hose clamp on the crimped bit of tube to hold the wheel in place -- took about six blocks for the wheel to push the crimped tube off the end of the axle.

I redid the crimped tube -- really tried to put in a deeper crimp. This got me all the way West down Broadway Avenue, from Columbia Street to Granville street-- about 1.2 km, before I could see that the crimped tube had popped off the axle's bold end, but, this time, hadn't actually fallen off. The crimp just wasn't that deep, but I could snap it back over the axle end. Tomorrow, I'll take one more try at deepening the crimp, but it's an aluminium tube, and there's a limit to the abuse it'll take before it just cracks, and crumbles. Click the images to enlarge them.
Fix Number. One:
Done before bed; involved winding heavy coated steel wire around the axle, spring-like, to fill up the gap left by the bearing bits. Made it one block the next morning, before the patient rejected the transplant.
Fix number two:
Used an aluminium handlebar, which had the diameter, and wall thickness to both fit over the axle end -- which looked a lot like the end on a carriage bolt -- and inside the wheel hub. It did not fit over two bearing sleeves, still on the axle, so I cut three, roughly, half-inch pieces off the handlebar, and cut one side of each lengthwise, so I could open up the diameter, slip each of them on the axle between the bearing sleeves, and close them back down to their original diameter.

I borrowed the chisel -- a flat cold chisel for working stone -- Definitely want some of my own. Chisels are like the nuclear option in a toolkit.
