[SEL] Tandem Trailer

[Andy]

Hello All, I remember a while back, there was talk about Tandem Trailers.
I'm in the process of building one, and I need some help with the
configuration of the spring hangers and a method/style of a tailgate. The
springs I've seen, some are hanging down and some are up on the shackle
side, with the spring shackle in the up position it looks like the rocker
will hit the spring, the way I'm inclined to do it is have the spring
hanging down from the rocker, and the shackle plates angled back, so when
the weight comes off ( i.e. going over a bump) the axle, the shackle will
hang straight down and won't flip over above the rocker? Also where to mount
the Rocker mount in the centre of the main frame or just back of-centre, I
think the idea is to have a positive weight on the draw bar, if I have the
rocker mount in the centre of the frame, won't the weight of the draw bar
(and spare wheel) give it the correct positive weight I need? The Tailgate,
I'd like to incorporate a ramp in it as well, so it will be fairly long, or
high when in the up position, how would I do the hinges? I don't have an
idea on this one, I was going to build the trailer, and then work out what
to do. This trailer is going to be use for my engines and/or a Section Car
(Speeder) or would it be simpler to just have two ramps, but how do I attach
them to the end of the trailer easily? to take the different widths of the
Engine trolleys. Any help would be great.
