Uhu02 "Discovery" Model

I'm considering many different ideas for the spine support.

My concern with a wood dowel is that it will bend (warp, sag) over time - even oak.
PVC pipe and acrylic rod will have sag.

Maybe thin-wall brass or copper tubing filled with expanding foam?

I do have a 1/12 Gemini capsule w/ docking target hanging by a single line over my desk in the basement (location: New England, US).
I used a wood dowel down the center of that. I does not seem to have sagged over the last 4 years, but with the disparity of shapes, it would not be too noticeable unless severe. The length is just over 36".

With the Discovery, and the repetitious shapes, I think any sag would be much more noticeable.

Thoughts anyone?

Im thinking that a 3 point system to hang the model might be the best option...Start, middle and end point...leaving the middle adjustable for any sag that may develop?

JohnJohn,
That's probably going to be the best way to handle it.
I like the 1 point hanging system because it gently spins easily. But sure could still make that happen with a 3-point system.

I do have to say that on the Gemini, the wood dowel has only about .25" thick and it has held up. you can see a little point sticking out the end on the Target in the photo.

Sorry for the double post..there seems to be 2 identical threads but...

Thanks for the heads up on 13X gents

Bit of note here...I went to local Hardware store this morning and brought along a sample of page two, to use the members as guides for suitable Diameter Dowel, Got one that I was happy with as you see in Picture 1 but when I attempted to wrap it with the main spine members I got a significant gap as seen in Picture B.

Both pages were printed with same scaling sizes and I have cut as much of the black line off the spine member...any hints or tips?

Thanks in advance

well, there's a couple of ways you could deal with this.

1: cut the holes in the hexagonal widgets a bit smaller(just inside the black line), which is probably what I'll do.
2: cut thin strip from a second printing of page one to fill the gap. (I may do this as well).

As said above, I'm going with 8mm dowel.

Hi, I see on Uhu's site something about Gen11 but I can't get the page to translate very well, would I be right in thinking that he is working on Chitty Chitty Bang Bang?
