Or legally on any unbraked trailer! (and probably not on a braked single axle trailer based on a Landrover either)

The original idea with the springs was to lose a couple of leaves and rebuild them myself with a shorter bolt through the middle, maybe 3 or 4 of the 11 leaves should be sufficient, and lose the shockies (these are stuffed anyway).

Does anyone have photos of similar conversions that might give me ideas?

I will probably post progress pics as I do it, if it gets that far of course. A bit uncertain what to do with the front.

Ive got a thread on here somewhere thats got a copy of the chassis layout and where I cut/fold them.

So is there any truth to what someone told me that you can't use a hollow axle and have to use a solid one? I thought most axles on trailers were hollow, I can imagine how heavy a 40mm square axle would be if it was solid. Someone has suggested that a hollow axle would be illegal but there appears to be nothing to back this up in the ADRs. Any thoughts? After all a diff housing is hollow. Most old boat trailers have hollow tube axles. I found a really solid piece of galvanised tube (old water drainage pipe actually) with a 4mm+ wall thickness and about the same size as the diff tube - pretty heavy and very solid. Hopefully should suit.

your standard 40/45 mm round/square axles are solid. You can readily buy just stub axles to weld into a suitable tube, so hollow axles are not illegal. The onus is on the manufacturer (owner/builder in your case) to ensure things are adequate and safe.

the only ones I know of to be a tube rather than the bar are the ones with the mounting flanges welded on and those are a rather thick tube.

If you know a good welder you can adapt the mounts from a rover axle (as opposed to a sals) onto an axle, if you want to go for a hydraulic discs on the rear let me know as I'll be stripping the back end of a disco 1 in the next few weeks.

(check your PM's)

I'm doing a similar trailer build - using the chassis, suspension & axle off a discovery 1 with a series tub mounted on top.
Retaining the triple link suspension & full axle with the diff centre removed & blanked.
Here in NSW a home built trailer requires a weighbridge certificate and blueslip inspection before it can be rego'd.
Only a coat or 2 of paint & it will be finished, but its been like that for nearly a year:o Where does all that time go??
I'll post pix once its done (hopefully not another year:D)

To qualify for the cheap rego ($52) and no yearly inspection in NSW the trailer must weigh 250kg or less, a landrover ute body and chassis will be well over that amount, so no chance of cheap rego or no yearly pink slips, Regards Frank.

Thanks Frank - I recently became aware of this, & as a result I'm going to refit the calipers, put overrun brakes on it & register it as heavy as I can with a single axle.:D

But should be quite feasible with a chassis made only as strong as it needs to be plus the ute body.
