Since you are using stub axles I would be tempted to upsize from "Holden" size bearings.

In my experience the small outer bearing fails all too quicky when loaded up with 16" rims and heavy tyres. Ford slimline would be the absolute minimum that I would use on what will end up being a relatively heavy trailer...

Better still go to a wrecker and scalp the front hubs n stubs from a 75series or 80series to go with those wheels you have. You will then have a stub axle to bolt onto your axle with full size hubs and bearings?

You mentioned that your axle is 50SHS 5mm wall. Are you running leaf springs on this trailer?

yes l just found today that the stubs are old Holden's and i will be changing them or for stubs welded into the tube instead to suit ......yes I'm using leaf's ?

Well what a day...the BIL and i got stuck into the chassis today.....nice work for a day i say... https://www.aulro.com/afvb/


Tacked out the main chassis then seem welded all the joins ... and my first go at for real "holy crap" this is for real weilding..lol...oh and BTW, gee this aust steel is good stuff, using 50x50x5 SHS and the hole frame didn't even buckle a twing.....or must just be that I'm a brilliant welder!!!.. https://www.aulro.com/afvb/..... https://www.aulro.com/afvb/..... https://www.aulro.com/afvb/...

lining him all up ...nice fit....love when a plan comes together... https://www.aulro.com/afvb/

https://www.aulro.com/afvb/images/imported/2010/08/1318.jpg

Springs, and central draw bar tack in ...decided to go for the draw bar on bottom of the chassis rather than butted up on front of the front bar as previously planed, after some discussion (read procrastination) felt it would be a lot stronger, so did this with the side bars as well ....the draw bar is 240 to the center on the tow hitch so worked to plan...need the space becuse i have single barn style door and i want to be able to open the rear when the trailer is on, also im not the best backer!!.. http://myswag.org/forum/Smileys/classic/embarrassed.gif

50SHS5 is a reasonable chassis choice, certainly will take a hiding!... but maybe need to give the draw bar more verticle support. Just to limit flex and fatigue in the A-frame and draw. You could either increase verticle section size (100x50) or perhaps run some ladder bracing using 16mm round bar?

Im not in love with your choice of springs but you will learn ;)

Its nice to see another trailer project coming together!

If I wasnt so lazy Id take some photos of the triangulated 4link boat trailer I glued together this morning!!!

Had some more fun today....hitch plate and jockey wheel in place, will all come off for painting, so decided try it on for size and line...found that there is a little to much flex for my liking (read only a little, but will need to beef up the center bar for the planed additions on the draw bar) He is going to need some weight, atm he's like a mouse on a hot coal box...we loaded it up with a few 100 plus kg persons and basically squashed the mouse ..but it early day yet....still need to add draw bar box spare wheel, Jerri's and all the pieces back together ... other than that he is exactly has i planed atm.....

If you want to brace up the 50SHS vertically then the easiest solution will be building a ladder from M16 rod beneath the two A-frame lengths. Space them 100mm from the underside of the 50SHS with ladders at 600 centres. Run the ladders from hitch plate all the way to spring hangers.

The whole "mouse on a hot coal box" is a function of the short overall length leaf springs. It just is the way that it is... The solutions are many and varied but none of them include what the "trailer industry" consider standard!!!!! Show me a vehicle with a front or rear axle load that weighs ~750kg that is using a leaf spring that measures ~800mm in length. That should give you some clues as to the suitability of short leaves for load carrying and handling. Sure it "works" by keeping the wheels from hitting the guards but then again some would argue that a big mac is a nutritious meal?

Either way mate you are having fun and learning. The overall design looks good and the trailer will serve you well until its failings will guide you towards "Mk II" which is always an improvement!!!!!

A bit more done today......as said a few days ago we strengthened up the draw bar buy adding in another piece of 50x50 tabbed in and seem welded at intervals of every 500 or so ....has worked a treat, once again, thanks for the advice on this ..

welded up the frame for the draw bar box and reinforced mount for the spare....the whole box will be clad in al tread plate and door will be as the same as the previous idea above out of 4mm tread plate .....got a hold of a three jerry can rack for the front of the box and, will have to post a pick when we get there ..... onto cladding on the weekend and then clean up, and on to painting...also added the bike rack hitch to the rear of the trailer for the kids bikes, ..... https://www.aulro.com/afvb/

Been waiting for your update! Coming together now and looking good!
I like you design of front box, nice lines and will prevent hangups at the front of the box when winding amongst tight tracks.

Hope Im not too rude but a couple of suggestions.

-Buddying up the 50SHS has helped but you still may have fatigue issues where the second SHS tapers, as well as where the outer arms flex at the tub.. M16 roundbar is stupidly cheap, run a length 100mm away from each of the outer rails on the underside from the spring hanger all the way to the hitch plate. Will give good flexion support and they double as skids if you ever have to drag the trailer with no jocky. See dodgy paint drawing for the idea.

-Your 25SHS box and wheel carrier may need some triangulation despite the relatively thick cladding. Id be running a diagonal brace from each lower corner to the wheel support centre upper corner. And then depending on door design and compartments some diagnonals from front to back. Otherwise all the bracing will be a function of your cladding fixation which if you use say Sika and M6 through bolts may be okay but diagonals from 2SHS will be cheaper! Then you can just rivet the panels on?

Mate thanks for the advice, much appreciated

am procrastinating over more bracing for the box, thinking of running a few pieces of angel iron to the front and rear of the box to add a shelf through the middle of it this may give it some more bracing??...the tyre mount has a piece of 8mm steel plate between the two bars running front to rear of the mount and the tub mount has been modded to bolt through the cladding and the plate .... i see you point about the draw bar, but I'm going to give it a run and see how she holds up, I'm 130kg, my BIL is 100 and my younger bro is 120..we all stood on the draw bar after the bracing was done and it didn't more and cm ...so failing the trial ....ill probably add you idea in at a later date ....

- a centre rail will add very little for structural rigidity to the box - you need triangulation!!!!! Tieing the box to the tub will help in its rigidity when static but as the draw bar IS going to flex it will actually put more load on the box and may lead to failure?

- the issue is going to come back to the draw bar ;) a static load of 350kg is nadda compared to a 749kg trailer flexing on three sections of 50SHS bouncing down the road. To test this flexing, remove the front box, fill the tub with a few hundred kg then get someone to tow the trailer whilst you drive alongside the trailer (somewhere safe and preferable mildly uneven road surface) You will be amazed at the amount of flex that will set itself up at the junction between drawbar and box in a dynamic situation.

Flexing in and of itself is not a bad thing (steel can be used in its elastic range), you can make a trailer too rigid BUT in my experience for offroad trailers its best to control flex in the suspension rather than at the aframe.

Persoanlly I would traingulate the box making it essentially a self supporting structure attach it to the draw bar with 30mm of clearance to the tub and then run the ladder frame under the SHS. Then after using it for a season and learning - Mk2 will use softer suspension :)

......got all the alu tread plat cut to size for cladding the box....(after cutting, a few tips, always cut this stuff with a metal aluminum circular or jig saw cutting blade, and when cleaning the edges up use a flapper disk working back wards rather than the normal forward motion on steel)......clad the box today (rivets and silicon) managed to get a hold of a jerry can holder of an old trailer, will mod it to accommodate two Jerrie's as in last few picks the front jerry box....

https://www.aulro.com/afvb/images/imported/2010/09/1462.jpg

added a few upright stems to take the future stone guard ...the jerry box is bolted in via angel mounts along the drawbar..

https://www.aulro.com/afvb/images/imported/2010/09/1464.jpg


has come up well i thought .....the tow ball weight with the box, spare and Jerry's full of water (with the tub on !!) is 60kg, only leaves another 60 to be over the recommended weight for my tow gear....should fine, surprisingly well balanced ....

https://www.aulro.com/afvb/images/imported/2010/09/1465.jpg

removed the tub for cleaning up and painting tomorrow, will do the chassis first and the tube second , the box will be all painted the same color as the tub and chassis ...

I assume the stop light bulbs are either bulbs with a single filament of I think about 21 watts each, or bulbs having two filaments, where one filament is brighter than the other, the stop lamp filament being the 21 watt filament.

To check the trailer wiring, I would just apply +12VDC from a battery directly to the wire that is supposed to feed the stop light filaments; run the ground back to the battery so that you know you have a good circuit.

I presume that both stop light filaments will function properly so this probably means the solution is either with the ground between the trailer and the tow vehicle or the tow vehicle plug, (or trailer plug).

I expect the ground between trailer and tow vehicle is OK as you say that the other lights appear as they should.

The problem then comes down to how the brake lights are wired on the tow vehicle and the trailer.

Most EU spec brake lights are seperate filaments from the signal light filaments. Most North American spec vehicles share the signal light filaments with the brake lights. In other words, you will have either two brake lights on or one brake light and one signal light functioning at the same time with the NAS wiring setup.

If the trailer setup is different from the tow vehicle, then that can be a problem - not insurmountable, but a bit of a challenge.

If both the trailer and tow vehicle are wired the same, then the problem is probably in the conlectors, or at least solvable at the connectors - or it is just a ground thing with one of the trailer lights. I say one, as usually one bulb is ground OK and the other, not so, so that side of the circuit tends to act as a ground and things do not work very well but are hard to trace.

Also you might try different trailer bulbs as I have seen defective new bulbs and finding that is near impossible as the bulbs look good. This is the best first place to start - replace the bulbs as new defective is not uncommon given that most stuff comes from China now.

Thanks mate, all came down to having to earth both stops rather than in a circuit if that makes sense, been running fine now on many different vehicles without issues....

I forgot to mention how impressed I was with the end result.

When I looked at the pictures of what you started with, well, I kind of wondered.

There is quite a contrast between the before and after - a labour of love I would say. The checkerplate texture metal sheeting really does work well.

I do like the colour choice by the way - kind of classy and the checkerplate around the tail lights, impressive.

Would be great to figure out how to reinstate photo links .. I've paid the ransom to photo bucket but the link don't just reinstate themselves.

And can someone tell me why I'm unable to edit my posts in this thread ?
