Hot dip gal is great, but a big draw back is the heat will buckle the big flat sections so the pro's say .
So i think i have to rule it out.

What sort of big flat sections do you have? Zinc-spray and electroplating are your best options if you have platework. Corrugated deck panels must survive hot-dip fine, plenty of commercial trailers are done that way.

Dougal,

The trailer has three ribs that are 1.8m wide in the shape of an inverted roof truss with a depth of 470mm.
S im thinking of the zinc spray option.

My Profender Piggy back 2.0 remote canister shocks have arrived. I'm very impressed these are big shocks will take a beating.
I had the engineer look over my design all looks good, tests come back clean but he suggested a couple of personal changes nothing big that i will take on board. Still waiting on the air spring to show up .
I will now be looking for a laser cutting company on the Gold Coast area to do the cutting for me.
I have found a complete from wheel nut to wheel nut front axle from a Disco to use the hub & disc brake assembly that will give me the correct stud pattern for the sawtooth wheels to match the tow vehicle.

Cheers

If you run with front stub axles - just knock the CV spindle bearing from the guts of it
That way you only need to machine the axle flanges a small amount to accept the stubs

You could always machine flat the backside of the stub axle but then you lose the location properties of the step and they become custom stubs if you were to scour the stub (pretty unlikely) and needed a replacement

What travel will the springs/shocks be limited to?

S

100mm of up travel & 200mm of down travel.
Will post some pictures over the weekend of the gear.

Cheers

Very nice indeed - as I mentioned above you will never use 200 of down travel on a trailer so if geometry gets the better of the central swings arms limit it
I really like the central spine concept - I look forward to seeing how you pull this all together
Great build
