Next question:
One of the little niggles with the bolt together trailers is the way the two draw bar members are bolted to the rest of the frame.
As far as I can see, the top plate of the C channel of the draw bar is bolted to the bottom plate of the side chassis member and of one cross member.
See illustration A. It's not a lot of metal taking all the stress.
Has anyone done illustration B? i.e. use a long bolt that will reach right through all four plates, put in a couple of spacers so the steel doesn't crush (the red bits in B ) and at least bolt 4 plates together instead of two?
I hope my attempt in MS paint demonstrates what I mean.

Sorry I did mine as per the manufacturer's instructions. For what its worth I have had no problems.

I know of a guy down under that uses; Bostik product called “Simson ISR 70-03
for gluing a aluminum deck to a steel trailer.
Says use small pieces of 3m tape or weed trimmer line for spacing so there is no squeeze out, and thus insulates. Very strong and he build's some very nice trailers.
Must be available & he says its cheap.

Do you have a Bannings? My daughter was at one yesterday and told me I would like it. Way better than Home Depot.

I had a project a few years ago that I wanted to use SS staples on but once I saw the price just used what I had. Like Tony I have never seen rust on the staples.

Yes we have Bunnings. The nearest is 125 miles away. As far as travel distances in South Australia go, it's a mere walk in the park/
