Motorbike Trailer #6 - W.I.P.
Seeing as my own trailer is on the backburner at the moment, and I can't get hold of the bloke who ordered a new 8 x 4'6" that is ready for him to collect for painting, I've been asked to look at fixing a Motorbike trailer that a local friend of ours had a guy start for him as a bit of a sideline to some other welding he wanted done.
I wasn't quite sure what I was going to find when I got there, and I still shake my head in disbelief when I looked at what I found.
Now, bear in mind, this guy had the wheels and tyres ( a set of 100 Series L/cruiser 16 X 8's with 275/70R16 tyres ) to measure everything from...

Those guards are standard 9" wide to suit passenger car tyres. Not a hope in hell of covering the the big wheels and tyres supplied by the owner.

Not a big fan of weld on couplings. Not the easiest thing to remove if you damage them. Especially if they're welded on like this!!!
Attachment 160599
I started by removing the bike channels, and to contemplate the next step.
(All that angle is welded on, on edge to the top of the chassis...)
After a couple of days spent getting some quotes, taking stock of what we had, and a discussion with the owner, it was decided to start from scratch. I will use most of the angle iron from the cross rails, and where I can, other pieces salvaged from the "wreck". The guards are almost a write-off, the drawbar and chassis were cut and bent from one length of 30 x 65 (drawbar is only 3-1/2 foot long anyway), and the axle is a 39mm round Holden bearing'd job, that's 4" too short, let alone not being the right bearings for these wheels and tyres.

So I removed the longer pieces of angle to start with...
...and cut some new chassis and front cross rails and laid them out for tacking together.

Today will see the new 50 x 75 drawbar cut to size, but will have to wait for the new coupling plate to arrive before it can be welded on. This is due to the fact that because of the height of the trailer with these wheels, and the restriction of the guard height being limited by the foot pegs of the bikes, for the trailer to sit level the coupling will need to sit under the drawbar... and then some!
I'll play around with the light mountings at the rear too.Too many projects, so little time, even less money!Are you a registered member? Why not? click here to register.

I think what I'm getting out of this story is can I use a "borrowed" shopping trolley to cart around my welder and bottle?! (photo 6)

Some pics from Sunday's work;
Drawbar cut to length. I tapered the end to neaten the coupling end. These will be capped off later.

With the large diameter of the tyres, and the height of the guards being limited by the foot pegs, the chassis will be quite high off the ground. So the trailer sits a little closer to level, I need to step the drawbar as well as locating the coupling underneath.

5' drawbar, again. My customer also hates backing a trailer with a short drawbar.

Sad thing is, this wasn't a wreck as such, it was being built as brand new...
