Thread: Plan B trailer build

photo of it back from the galvanisers

they drilled enought holes in it, have to buy a packet of sinkers now.

It certainly adds up fast.

I was especially interested in the cost of galvanising.

Should do the job for many years.

Wasn't the cheapest quote for galvanising, but was the closest bath, so I argued them down to close to the cheapest quote.
costed weight was 342kg @ $2.20/kg (+GST)

Funny thing is I'm now trying to sell my 7x4 for less than the cost of the galvanising.

Of course the unfunny thing is that somewhere along the build I lost 20mm of width and 100mm of length and now the boat don't fit. I reckon it shrank in the galvanising bath.

and I still haven't tried the camper top on it to see if it fits.

Now that's a big d oh

D'oh is right, particulary as I was continually telling myself to check the boat fits, but with all the pressures of freeing the carport back up, it never happened.

I reckon it gives me the ideal opportunity to build a boat to fit the trailer now, of course I would have to buy a mig that could do aluminium (the mig I built the trailer with is borrowed, must return it one day, but the gas bottle is still full).

Somewhere along the way the conflicts between making the camper fit on top (which I still haven't tried yet), the boat inside and the floor out of a single sheet of ply made it all come unstuck.

In reality I will probably cut the excess vertical off the back (which are there for the camper to mount to) which will allow the boat to fit in width wise (as it is only the gunnels that stop it, and they are higher than the trailer sides) and make a bracket that will allow the front tailgate to be fixed at an angle to give me the additional length I need.

Gee lost count of how many times I test fitted with the boat when building the boat camper trailer. In hindsight still would have done a couple of things different, but the boat fitted upon completion, so am content (for the moment)
