I've been working on a castle tower for which I need a spiral staircase.
Unfortunately, I sold off my HP sets that had the prefab spiral staircase
parts,
so I had to come up with something myself. Here is what I have so far. In the
ldraw file, I ommitted the 1x2 plates that I put in between the wedges to give
the staircase more balance (they are in the first step, but I forgot to put
them
in subsequently). I am still working on making attachment points at the top
and
bottom of the staircase. I would be interested in hearing about some solutions
for making those attachments from people in the group. Also, tips on improving
stability and locking the staircase in place would be welcome.
