I talked with my mother about the single-axle option, which would require me to drill through the wheels and set them to rotate on the axle, rather than be stationary. She indicated that was not a preferred option. The wheel hubs are solid on the outside. She wants to keep it as original as possible.
Boring out the block and fitting a bushing is just going to lead to the same problem happening, the load being focused on the bushing will compress the wood in that spot and itll just loosen up over time. As it is the area of the axle thats being supported under the cart is just too short and isnt distributing force nearly well enough, you need to extend the axle, and running it the full length is the way to do it. If you wanna get fancy, hop on eBay and grab you some pillow block bearings, run the shaft through those
Would it? I would think that boring and installing a bushing would spread the load across the wood a bit more. If it ever wears again, the bushing could be pulled and replaced.
Last method worked for quite a few years, why not simply rebuild it as it was?
I'm not sure how long it actually "worked" effectively. Even so, it's new life will be to cart a 40lb oven on a fairly regular basis, so I think it needs bolstering/strengthening.
I think this is my current plan:
- Bore the wheels to depth, and install full-length bushings. The wheels will still be stationary related to the axle. I'm not sure epoxy would be any better, as the epoxy, and/or the wood would still eventually compress.
- Rather than full-width axles, go slightly less than 1/2 across. I could bore out more of the axle block to accommodate longer axles, and install bushings at both ends of each block. The new axles could probably be 3x longer than original, so the load is more even.
