So another quick update; the ladder system
For the ladders i used the 1/32 scale styrene ladder from plastruct (item Nr. 90674). The package holds 2 very long pieces, which were cut in half to have the four ladders needed.
But since the top ladder needed to be wider than the telescope boom, i had to create the top one myself
![Rolling Eyes :roll:](./images/smilies/icon_rolleyes.gif)
, one ladder remained as it was and the other two had to be narrowed.
At first i thought by just laying on top of each other, the ladders would expand and retract properly, once attached to the related boom parts; wrong
So in order to function properly i had to add "L" profiles to the ladder underside and strip styrene on top to create a guide rail for each ladder.
