Started building my trailer...
Frame: 40x40x1.6 RHS, 2 mtr long, 1.1 mtr wide, 1.25 wide over the wheels. Big enough to put a Swag on or a roof top camper or a trail bike or a quad :grin
It's going to be a convertable... i.e. flat deck then add a box with lid or a camper on top... That is why the frame is a little heavier than some..
10x6" mini mags with boat trailer plastic guards
Still got to make the suspension yet, which will be independant swing arm with CB250 coil over shocks like Brocks http://ozstoc.com/index.php?topic=258.0 (http://ozstoc.com/index.php?topic=258.0)
Got a set of Mini hubs and swing arms from the wrecker, cut down the swing arms to stubs then weld on my swing arms. I have left the brake backing plate mounts on in case i want to fit brakes later...
I'll post more pics as i go...
-
Impressive, but I would have thought that 25mm would have been enough.
I have thought about redoing mine with the cross tubes being reduced to 13 mil to save weight
-
Yeh, it's probably a little heavy, but because it is going to be a flat deck with no other supports, i figured it had to be stronger :think1
Given that the bike weighs almost 300kg and the loaded trailer is allowed to be up to that weight, strength became more important than weight.
This trailer will go behind the car at times as well...
-
Its all experimentation. I have had my 105Kgs on my chassis with no flex, and Im sure it would take 300 easily, your certainly will.
The independent suspension is the bit the is the hardest to design, I will be interested to see how you do yours.
:thumbs :thumbs :thumbsup :thumbsup :thumbsup
-
I've got the suspension in my head.. now i only have to get it to the steel :||||
Found this 360 degree swivel coupling on Ebay for $146 landed out of the US. Should make things easy on that side of things.
-
Havent gone for a swivel hitch at the moment, I am going to wait n see if its needed. If it is then I will put on the thinking cap again.
-
I love the wheels and guards :thumbsup
-
Brock I have the swivel hitch on mine and it allows for a lot more lean angle when required (read fun) without limiting the relationship between the trailer and bike connection.
-
I will have to look at one and see what I can do.

I've seen these Flexitor suspension units on bike trailers and would consider using them if I was to build a trailer. Available from SA Trailer and Chassis.
-
I did look at those, but they were expensive.
-
I looked at them too but the lightest of them are rated at 750kg per pair, so even fully loaded at say 250kg, my trailer would not even be flexing them...
-
ok, more pics.. suspension this time
also ordered a pair of shocks of Ebay to suit small quad..
adjustable spring pre-load and shorter than the CB250 ones which were 320mm long, these are 260mm which means i can stand them up straighter... about 80 to 90mm of travel which should do.
swing arm suspension...
stuff a bit of 25mm RHS down the hole in the cut down stub axle, weld a bit of 30mm RHS on the end in line with the axle, fabricate the rest as required... the cross bars are to stiffen it to stop twist.
used 22mm x 12mm nylon trailer spring bushes for the pivots... put the bushing tube all the way across to square everything up, then cut it down after..
next is mounting plates and bolts etc...
all the while, using the wheels against the trailer frame to line them up, squared to the ground, centred on the frame... hopefully it tracks true :thumbsup
-
photos, I demand photos or its the sin bin :well :well
never mind, they just took a while to load
-
What site did you get the shocks from, they may suit my suspension as well
-
somehow the photo's didn't go up so i had to edit the post and attach them again :-[
shocks off Ebay, here.. http://www.ebay.com.au/itm/200763022593?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 (http://www.ebay.com.au/itm/200763022593?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649)
there is some cool looking resevoir shocks there too, 20mm longer, $20 dearer and i thought :think1, why!
-
Interesting, its a bit short for my set up. I could re work the rear mounts again I guess....
-
the more you stand the shocks/springs upright, the better they will work.....
i intend to place the bottom of the shocks right down at the rim edges so i can stand them up as much as possible
-
That is so true.
My shocks are from a Z250 Kwaka, and are 300mm. The shortest I could find at Two Wheel Wreckers. I had to cpmromise with the angle and the overall height I was looking for. As Terry says, it works, it holds my 105 Kgs bouncing over the wheel :grin :grin
-
yeh well Brock, if it works it ain't broke, so don't fix it :p
-
Haven't done much recently until yesterday... more suspension, now it actually stands on it's wheels!
Not quite what i had in mind but the springs on those shocks are very strong so i had to reduce the travel/increase the loading by laying them down. For 50mm of wheel travel, the springs move about 10mm! What this does tho is give me a nice soft initial wheel movement that gets harder with travel. e.g. i can 'bounce' the trailer easily for a an inch or so but i can also stand on one side (95kg) and it only moves another inch. Also, i have the ability to preload the springs when the loaded weight is higher like 250kg.
Anyway, it is all trial and error so will see how it goes :)
-
Yep its fun working that stuff out aint it.
My spring/shocks will take my 105Kg bouncing on em just nicely
-
The spring units look to be opposite way to normal on a bike swing arm, is this a better way to mount them?
:bl11
-
probably not, but because they are so strong, i had to reverse it to get leverage... they are mounted on the swing arm from drop down mounts so 'up' on the swing arm becomes 'push' on the spring.. looks like it works so we'll wait and see :)
-
Its in the same style as this one on my trailer, just with more mechanical advantage.

A bit like a seesaw, but changing the pivot point
-
a few more photo's for what is now an almost completed trailer...
it gets a floor in it tonorrow then i'll mount the box (rood top luggage box off a car) and the esky
will post pics when that is done
-
Looking good. :thumb :thumb :thumbsup :thumbsup
-
Do you take orders, will you ( and Brock) have the trailer/s at Middleton??
Cheers
Dave
-
ha ha, maybe :wink1
-
Trailer floor is done now, couple of pics attached
next job is mount the top box and esky! :)

That looks superb mate, first class travel there, makes all the renovations I am doing to my bike seem a little second hand lol
-
Beautiful, looking really Schmick :thumbsup
-
Love the fatty mags all the better to corner with!
-
I admire you guys who can 'glue' steel and stuff. Well done Leethal. Looks 'better than a bought one' .
-
At long last, what with moving house and settling in and all, i have finally been able to get a couple of pics done with the trailer 'finished'.
I do intend to paint the guards blue like the bike, but for now this is it.
Pictured here with the luggage box (4 wing nuts) and the very important esky (4 clips) attached!
I have also used it as a flat top with a 90cc quad on board, works well!
This tows and rides pretty damn good, have done about 500k with it now and also 160kph the other day and it just sits there saying 'bring it on buddy!'
Got to say tho.. watch the throttle when two up and trailering, man it sucks fuel if you are heavy handed... not bad when cruising at the speed limit tho!
cheers
-
Leethal, that's a bloody great job.
A credit to you.
Cheers
Dave

Hey Leethal did you make your own tow bar also? Looks a little different to the one I run, and similar to one I am looking at trying to get made which hides most of the bulk.
Any photos if you have changed the design would be good please.
Love the trailer too bloke. Looks like many happy miles to be be had with the set up.
-
amazing... how many hours did it take to make? do you have blueprints :grin
-
Hi Leethal,
That's scrubbed up very well indeed, and with a matching paint job, it'll go with your stunning bike really nicely. I really like the idea using the flat-bed as a basis for a modular/adaptable trailer. Well done, and see you at Middelton.

I just made a 25 x 25 x 3mm rhs bar that runs from the muffler mounts each side and behind the wheel, set high (just under the rear guard) with straps down from the top behind the panniers, then got my mate who does stainless (20 x 1.6mm tube) to do the bits you can see... pretty easy for the bit i did really. The ball is 1.7/8" which is USA and i'm not even sure it's legal here but no-one in SA cares. The coupling is 360 degree swivel, bought off Ebay from Hoosier Hitch USA (Charles VanHoy) but i can see it will take a 50mm pressed steel trailer coupling available here.
More than happy to supply / help with any info that will help my fellow OzStoc members :thumbs
cheers, Lee

ha ha, blueprints!
It all came from my head and was cut and shut twice before i was done! Maybe blueprints would have been a good idea.... >:()

Leethal, Were there any difficulties getting your home made trailer through inspection to get it registered? Engineering reports for load ratings etc....

Leethal, Were there any difficulties getting your home made trailer through inspection to get it registered? Engineering reports for load ratings etc....
Pete, as long as you have the important bits covered like tyre, spring and coupling ratings, stamped load rated safety chain, adequate lights and reflectors, wheels covered with mudgaurds and flaps etc, it is not going to be hard...
But, I have friend who is a trailer builder and he checked it out and was very happy that it was up to it's 250kg gross weight task. It is registered as 'homemade' with one of his VIN's on it. It never went to be inspected... like i said, no-one here cares...
The bike towbar, well, who knows... only a cop on a bad day might have a grizzle and i'll wait and see for that one! o:)
-
Trailer & towbar look awesome (nice and shiney :thumb)
Thanks for sharing Leethal :hatwave

This is whats available to the yanks, maybe us aussies can reproduce it too.

:wht11

should have looked first, check out www.flyingfishcampers.com.au (http://www.flyingfishcampers.com.au) and look at the "scout" camper trailer and the price aint bad either.
seriously thinking about this one,no more uncomfortable nights on hard floors.
:wht11
-
The 'scout' one looks to be the one to buy, and a reasonable price too.
:bl11
-
I'm thinking the price is for the Tent only and does not include the Trailer. :'(
:grin :blk13 :grin

I reckon you are correct Mitch..
