Scraping

 Similar to mine but I had to turn my hitch upside down to lift the tow ball because the jackup stand was scuffing the kerbs and boat ramp edge. Top job mate!

Congratulations looks like a great result. Why bolt on the mild steel RHS with everything being aluminium or was it because you couldn't get that type of section in aluminium?

 Pretty sure the reason was ease of construction, no welding. I doubt you'd retain member strength if you 'bumped' ali like that. For question on galvanic corrosion I reckon you'll still get corrosion even if you bolted ali pieces together anyway. I think he'll get plenty of life out of it. I'd just be spraying all the joints with lanolin or lithium to proof them a bit. It's all about maintenance at the end of the day.

Just to take it one step

Tue, 2014-10-28 13:56

Just to take it one step further on my previous comment. I look at the trailer and see what I presume are galvanised u bolts and galvanised connecting bolts and then the mild steel runner rails. What thought has been given to galvanic corrosion?

to go stainless bolts I would still be paying for them now and what do you mean runner rails? the only steel parts are the winch post and draw bar and they are galvanized

Galvanic Corrosion

Tue, 2014-10-28 15:01

Isnt that only really a problem while the trailer is in the water? Electrolisis?

Provided the trailer is washed down I wouldnt see that as a problem, but I could be wrong.

 Bradz galvanic corrosion is the result of 2 dis similar materials coming into or being in contact with eachother.

 

This being said the paint will act as barrier for the time being slowing down the process if it was to happen.

 still needs an electrolyte to take off.

Otherwise your car engine which has steel, aluminium, cast iron, copper, bronze, white metal etc all bolted together would cease to exist fairly quickly

Looks good - one thing I'd be doing though is taking that safety chain down to the trailer beam just in front (or behind I should say) of the winch post rather than the winch post itself.
