Brent, I'm on a budget !

Hey Frank and Brian, My
relative that has build a good number of nice trailers, likes to use Torflex
rubber torsion suspension axles from Dexter Axles. They have a nice clean look
and they are lighter then your standard leaf spring axles with the same load
capacity. This also mean you can get away from rusty leaf springs if you wish.
There attachment means is simpler as well.

Dexter
also carries a line of axleless wheel assemblies for those that want to be
able to lower a sub between the wheels with out the axles getting in the way,
and to be able to transport the sub with it having a lower CG when on the
trailer. These axleless wheels are much like the larger ones you see on the
semi truck trailers that pick up bins of freshly picked fruit, and then
transport them to the packing houses.
I've toyed with a few ideas for a
floating sub trailer that you could let most of the air out of the pontoons to
launch the sub, like some ski boats are launched from a float system that is
attached to a dock with a air compressor to refill the float system. But I
think I would rather have the floating sub trailer with it's small walk around
deck to stay on the surface so the launch crew don't have to get wet if the
sub is being launched away from a dock or other support boat.
Here are
some pictures of one of Aerocet's models of amphibious floats. The retractable
wheels with disc brakes are very nice. I have been thinking about a
larger floating sub trailer with two sets of wheels like this to be able to
handle the weight of my tow vehicle, when it's is being floated by the trailer
after the sub has been launched. But that's another story all together.
If I was making my own floats then I was thinking of making attachment arms
for electric thrusters, that are attached to the retractable wheels
assemblies, so that when the wheels where retracted, that the thrusters would
come down in there place to save on actuators.
