Another one from me - the "nose wheel" on my trailer was broken, as happens quite regularly it seems. This was the first time for this trailer however.
The central plastic rim/hub is quite simply cracked. Three options:
- I could be normal and go to the dealer and get an expensive replacement part, which would then include the whole assembly, not just the broken part.
- I could still be normal and go to the cheap aftermarket part shop and get a cheap replacement.
- I could act in true ERE spirit and make my own part from things I already own, with the help of tools I already own - essentially a free solution.
Disassembly took all of removing one pin.
Initially I thought I was going to need to replace the whole wheel, so I elected a piece of wood large enough to accomodate this.
With the aid of a chisel the remaining plastic pieces were extracted from the wheel, upon which I realized that replacing the centre piece would suffice.
A day when you get to break out the old trusty compass is indeed a good day. Measurements of the inner diameter were taken, and thus transposed to the piece of wood.
To start off an error was made, as the first circle went through a knot which I initially disregarded. Not to worry.
The rather precise circle was then cut out rather imprecisely with a jigsaw. I would of course have preferred other tools, but one must make do with what is around.
Putting to use a red marker on the various protrusions, and again wanting tools, this time in the form of a belt sander, I used a flap disc on an angle grinder to shape the new hub and a mallet for some gentle persuasion. This worked rather well, as the "tyre" of the wheel seems to be of quite good quality. Tough, yet elastic, and the wooden rim/hub did indeed seem quite well stuck in place in the end.
The assembly is again assembled and shortly after was mounted back onto the trailer. I don't usually make much use of wood in my mechanical work, though this time it seemed like a fair choice. This wheel doesn't see much action at all, as it mainly just supports the trailer when parked, or perhaps rolls a few metres here and there before getting yanked in place for travel.
This was as close to free as you get, and took about half an hour. We'll see if it holds up, but I acutally reckon that the biggest problem here may very well be rot, or of course a similar calamity to what caused this situation in the first place.
