I never fillet weld completely around the stub. I've seen too many stubs shear off with a load of gravel on the motorway. Just some really good plug welds.
nice one mate... i built a tandem car transporter without springs...towed mint..no point having springs if the load has springs, as we find with our speedway cars that they tend to wallow around as the car on top cycles through its own suspension travel..
Hi, square tube is used so it is easy to weld to frame of trailer. Also this connection makes for a stronger joint than a round profile. Round tube could be used thro.
I noticed at the end of the video, what seemed to be the axle welded to a frame (at 6:28). What is a purpose of that? Why isn't it suspended via spring??? Have never seen that sort of design.
We build a number of Tiny house trailers mainly with leaf suspension but some with fixed axles. See here for more info: weemakechange.co.nz/smart-tiny-house-trailer
@2:23...... much easier to file/machine/ grind a small flat area on the stub(haha) spindle for the length needed. Yeah, I know this was four years ago. :)
bigshafe Hey, decided to do it a bit different and save cost in the trailer by excluding brakes, suspension, controls, etc. The trailer is not designed to travel on the road but on the back of a truck as we plan to only move it very rarely. We also gained width from 2.5m to 3.1m. Read all about it on our web site here: @2014 Thanks
+Wee Make Change If it will not be traveling on the road why put wheels on it? Is it a legal thing because without wheels the local government won't allow it?
im making a dirtbike trailer my trailer frame is 1500 wide so how long do i cut the pipe for the axle ?? is it the same width or a bit longer or shorter?? plz reply thanks
+josh avery (SlingBlade Killa) Hi, you will need to make your axle more than 1500mm. See around 6:30 in the vid to see how much overhung we had which is approx 100mm. This will depend on your wheels and chassis clearance. Bassilly mock it up before committing and make sure it's all good.
Hey good question. You could use round tube but its makes to hard to attach to the trailer structure. Also square hollow section is often cheaper. Hope that helps.
Hi, the tiny house is designed to be lifted and carried by truck. So no need to spend money on suspension, brakes, controllers, light etc. See our blog post here for more detail: www.weemakechange.co.nz/2014/08/are-tiny-house-trailers-worth-money.html#.WEuni_l97EI Thanks
+Wee Make Change sounds good, I'm in levin and I'm doing a standard 6x4 trailer as a school project, I have started it but I was just looking at finer detail on the axel assembly
This setup should NEVER venture onto the highway. It would be unsafe except at very low speeds. It is suitable only for moving slightly and slowly around the yard, maybe? (and being very careful so as not to bend the axles). When there are two axles, like you are using, springs and equalizers are there for a very good reason. I have seen tandem (two) axles mounted without springs under a car hauler (using very strong tires that can absorb the shock loads, instead of springs). It can be done, but they at least need "equalizers" (a pivot point in between the two axles where the two axles can swivel up and down in relation to each other). Without that center pivot point? just traveling across any sort uneven ground (bumps or dips) could be very hard on the frame and tongue structure, axles and tires. Just jacking the tongue up and down to hook up and unhook for towing? could cause damage to your axles or frame. Travel over a bump or dip could cause one axle or wheel and/or tire to be overloaded and damaged while the other carries no weight at that point. Tiny homes can weigh perhaps 5000-6000 kilos or more when finished and furnished. Normal trailer tires can only handle those loads because they can share it equally. If you need two axles for the load? they must be able to conform to terrain and movement or they will be overloaded. Imagine when you need to turn sharp for maneuvering into or out of the parking spot? With no suspension (leaf springs and equalizers) to flex and give while the turn scrubs the wheels sideways, there is only the tire sidewalls to absorb that. With too sharp a turn it could unseat the tire bead and flatten it. The steel wheel rim, loaded that heavily, could cut your sidewall and even ruin the rim. Be very careful. Hopefully the finished house only has to move once slowly a short distance on smooth level ground with gradual turns. From the shop to the close by permanent parking spot it will probably work. If you want to sell this home to some chap someday who needs to move it across the country? It will need re-fitting with suspension before the trip. Much easier to just do it right the first time. With the amount of investment in a tiny house? it really doesn't make sense to skimp on this small detail. A complete tandem axle suspension kit would cost perhaps 1/2 the price of the tires this home will need.
