    Re: Aluminium Trailer Build Tandem Axle (On a budget)

    Had to top off the leaky hydraulic presses jack with transmission fluid as it has a leak, so far i have bent the aluminium to 7.0 degrees this gives me a width of around 1.49m i need something like 1.79m to suit my axles so shit is going to get technical from here on with the bending, my 20 ton press done it but i think i was around 90 percent capacity on the hydraulic jack

    where its bent to now there are absolutely no kinking not even the slightest there are no cracking on the bend or anything this is working out perfect so far

    Re: Aluminium Trailer Build Tandem Axle (On a budget)

    My cousin came over and gave me a hand this afternoon making the final bends we ended up at 8.2 degrees bends which gave me a width of 1660mm my old trailer is 1730mm wide with the spring back of the i beam i didn't want to try for perfection it could be a $1000 mistake by bending to far

    i need to pick up a new disc for the chop saw i will head to bunnings later tonight and cut the cross members tomorrow

    Re: Aluminium Trailer Build Tandem Axle (On a budget)

    Burnt out my $90 chop saw on the very first cut bugger! just bought a new disc for it too over $20 i than got out the trusty ryobi wood saw and it cut like butter, i grabbed my stainless bolts today with nyloc nuts will be assembling shortly maybe tomorrow, this coming week i will pick up the drawbar i will go with 100x100x4mm steel i will use a 100x100x4mm cross brace at the back of the drawbar which i will TIG weld out in the shed

    just remembered i don't have a saw to cut the steel hmm

    my trailer is only around 150mm 155mm wide i have to check my boat will sit over the mud guards as not to have rally dicky looking mud guards hanging out of the edge of the trailer plus it allows materials to go a little further

    Might be worth getting some penetrating die to double check for fine cracking.

    Re: Aluminium Trailer Build Tandem Axle (On a budget)

    You could put a second bend halfway forward of the first bend.

    Re: Aluminium Trailer Build Tandem Axle (On a budget)

    I cut my angles on the cross members at 45 degree it was too advanced of a cut i was going to run 2 bolts each side of the cross members and a U bolt on the inside but since my cuts were too aggressive i have no room to use the U bolts i now need to install 4 bolts each side of the cross members

    going to call another aluminium shop tomorrow i need another short length of alloy to make 2 more cross members i was going to go with steel but the alloy looks strong, the draw bar will attach to the most two front cross members not pictured yet

    last night i ordered the springs, fish plates,u bolts, coupling kit, brake kit etc... all up i am in this trailer $1400 all i need to buy is my draw bar, mud guards, spring hanger attachment plates, trailer lights and a winch post plus two steel plates for top and bottom where the V is up front and my bunks

    Rob If i put the die on it how do i clean it off? i only made the beds 8.2 degrees its nothing really

    Dig Hey dig i went with only 2 bends to minimize any problems

    Steve Some manufacturers run strait cross members it won't be a problem the trailer is 6.5 meters long mate that is plenty of length to dip

    Where are you buying it Gazza. There is a huge difference between buying at a Bunnings or Marine retailer compared to a specialist fastener supplier.
