I hafta admit that Ken has the right of it. There’s no way I could get MY paws around some of that stuff. As a negzampil, lemme tell you how he made them ladders. ig continues…
First, get two bits of brass channel from the KS Metals stand on the counter in your friendly local hobby store and cut them to the appropriate length[s]. They will be the side-rails of the ladder. Remember that one SHOULD be somewhat shorter than the other to take into account the curvature of the van roof. [Caboose is you are from down there.]
Then get some 1/16th dia alumin[i]um tubing and cut three pieces to replicate the rungs.
Beg/steal/sneak six dress-making pins, and cut them down to about 1/4", leaving the head on, of course. Make sure that you don’t inadvertently use a pair of those VERY expensive Xuron sprue cutters to do this, but a proper piano-wire-grade side or end-cutter. Please don’t ask why I know this, OK?
Drill a series of 3/64th holes in the rails where the rungs will be affixed, and push a pin through the hole, and thence into the hole in the alumin[i]um. A drop of CAA on the end of the pin will spread into the tube AND over the inside of the rail - joining everything together. Do this three times for one side, and then follow on by applying the other rail, thus completing the ladder.
The pin heads look just like the rivets of the real thing and the channel has the appearance of, uh, channel, adding a better appearance than that obtained by simply using flat stock [IMO].
Do this twice.
You can embelish the ladder by putting extension rails to the tops - mine were not made by me, but were off-cuts from a PE brass model of some kind that just happened to be the right size. Good, eh?
Many more handy hints and tips available, dependent on the weather.
