Thanks Simon, and all...

A friend tacked the thing together today and I got the boat off it. He'll repair it as best he can tomorrow and then I can drag it to the big city to see what can be done.

The frame of the trailer looks fine. The friend who welded the axle is a millwright so I trust his opinion. I've sourced a new axle "kit" near my other house, so I should be in good shape.

Now I'm wondering if I can have my cake and eat it too... Can I add two axles and make my own tandem trailer. These guys seem to have all the bits...

Having done it before, it is not too hard as long as you get your balance point right and that really depends on your setup and how much room you have to play with. With your size trailer it should probably work.

If your spring hangers are welded to your frame you will break the galvanising as you cut them off or weld on new ones. This will be a potential rust spot but being fresh water use, if you paint it with Coldgal, it should last.

Just remember that manoeuvring the trailer will be much harder when not attached to a car and that when you do tight manoeuvres such as at the ramp, your tyres are fighting each other and putting a lot of stress on the bearings.

There is a lot to be said for keeping it simple.

Stoo; Did you already purchase the axle?

I was thinking about going with a torsion axle setup when it came time to replace the axle (which may have been hastened by a failed brake system, but it's currently still hanging in there.)

My view is that with a torsion axle and disc brakes, there's a hell of a lot fewer parts that can fail.

Might be worth a look.

I picked it up Friday. I decided to replace everything.. axle, hubs, brake lines, actuator... even the bunks. I have a brand new trailer!

I was on the lake today and had a lovely 155' dive (in 34F water). It was a great day until I was attacked by a suicidal deer while I was driving down the highway... Pretty much totalled the entire left side of my Tahoe. Fortunately I wasn't pulling the boat at the time!

The trailer frame will only fatigue if it has been subjected to a cyclic stress beyond the steel's elastic limit.
Imagine taking some steel flatbar between your hands and bending it very slightly repeatedly.....the bar will return to its original shape and condition after you stop. Now if you start bending the bar more strenuously to the point that it stays slightly bent and continue to do this in a cyclic manner then the steel will start fatigueing and eventually fail.

The dimensions of the steelwork used in your trailer should be of such that it will never reach its elastic limit (unless overloaded) and should therefore never fatigue.

On my trailer build, i opted for twin axles for similar reasons to why you want them but also the fact that the load is spread over twice the surface area. Twice the running surface in the bearings means less stress which means less wear. I chose two 1000kg axles instead of one 1600kg to in effect give the axles and suspension an easier time.

Hope this helps


Simon
I went with two 1300 kg axles on a very similar rig to yours ?

I hate when that happens...

Glad you're OK;
