Yup, SJ is correct. The TOS Galactica is about 4 1/2' long and due to be pulled out of mothballs and finished soon, now that I have the lighting components.

Provided I can pull myself away from helping Bazookajo finish the suit of Cylon Armor... LOL.

I'll re-open a new thread to track my progress once I get her started back up. :mrgreen:

Fixed flight pods for now

Well gang,

I've been bashing it around in my head for some time now, and I just can't figure a way to make the flight pods retractable. The attached image illustrates the problem. The light blue lines in the top arms show the hull outline where the arms intersect it.

The top pair of arms are in the fully extended position,
the middle pair partially retracted,
and the bottom pair are in the fully retracted position.

I simply haven't been able to come up with something that works. The space inside the hull is about the same length as the upper arm, so the arms need to slide inside each other, or "telescope" somehow. On an 18 inch model we only have about 3cm (1 1/4 in) in which to build the mechanism, and it needs to collapse to at least half that size.

So, unless someone has a solution I'm going to design it so the model can be built with pods extended, or pods retracted, but no retractable landing pods.

Getting close now, but I've been very busy with work and other life stuff lately. Getting back on track now though.

TTFN,

SJ

Waw sjsquirrel,

It's going well ith the Galactica, can't wait to see more.
The retractable landing pods arms are two parts.
Part a goes in part B and then they go in the hull.

But I have no idea how the are built it (for real) in the colonies!
If they are fully extracted there is no overlapping.
Here is a big picture were you can see it.

I gues make it simple no retraction, it will make the construction stronger.
so we can run a round the house :twisted:.

But 3 feet long, thats 91.44 centimeters, frack me!!!

Perfect!

CJ,

Thanks for this :wave:. It's exactly what I needed to stimulate the old gray matter. I've done up a quick test in meta and unfolded it, and will start a test build tonight. I'll post pics and stuff as soon as I can. I've still been stupidly busy with work lately, and haven't had much modeling time.

Thanks again, and stay tuned.

SJ

OK, here's a quickie hand sketch of what I was thinking of for telescoping legs, for the BSG. As you have sectioned in the picture above, I thought of three separate sleeves the slide inside of each other with inner and outer folded lips that act as stops and help to reinforce the the leg strength. you can go with more sections if need be as long as each section has the same mesh so that they all....mesh...together.

The inner and outer lips would be folded onto each separate section of the telescoping sleeve and final assembly of each sleeve would be folded over the previous part.

Savvy?

Retractable Arms

Great news gang,

Thanks to CJTK1701 and Theo I've worked up a method for retractable landing bays. Instead of folded flaps though I'm using strips of thick card, or layered card.
The attached image illustrates the method, based on what CJ and Theo illustrated earlier. It turned out to be one of those "couldn't see the forest for the trees" type things. Once I got on the right track it clicked right in.

The telescoping portion of the arms are roughly square. The diagram below shows a cross section of the arms.

As piece 1 is pushed in, the red "plate" at its inner end hits the red plate at the end of piece 2, and piece 2 starts moving in, until it hits the end of piece 3. When pulled out again, piece one moves until the red plate hits the blue stoppers inside piece 2, then it starts pulling piece 2 along with it, until the red plate of piece 2 hits the stoppers inside piece 3. Simple, and very effective. The same technique could be used with cylinders to simulate hydraulics, telescopes, telescoping legs, all kinds of good things.

Last night I built a test piece using blue stopper strips on the outer edges of pieces 1 and 2 (more like CJ's original sketch) instead of the red plate, and it worked like a dream. I came up with the idea of the plates later, since it increases the amount the overall tube shrinks or grows. It might not be as strong, but I'll test this technique as well and find out.

Happy dreams!

SJ

Nice solution!! :) I was like you SJ, I knew how to do it but for whatever reason couldn't make sense of it in my head.

I was wondering, now that we well and truly missed our inyended Christmas release, are we going to be doing any fleet ships in the meantime before all the bugs are worked out for the Big G?

Retracting arms

Howdy all.

Haven't had much energy around 3D work lately. I've been more into building. Just got wind of the free model competition and have an idea for an entry too. Good thing I have until June sign1.

I've fine-tuned the landing bay arms and tested the two different techniques. Using solid strips seems to work better. The "plates" don't support the arms as much, but it may not be significant. As soon as I can I'll send some test builds to nothing and skupilkinson, and we'll see how it shapes up.

Skupilkinson, good question about other ships. I hadn't really thought about it. I've been focused on the Galactica. I'll take a look-see and if I can make something ready in between I will.

I was reviewing our progress the other day, and if you count them up, we've put 11 (eleven!) models out already. The big G will make 12. I must say I was actually surprised (and proud) at how many we've done so far. It certainly pays to sit back and think about what we have accomplished every now and then, rather than always thinking about what we still have to left to do.

Take care all,

Steve

True buddy, we've got alot done in the past few months I think. Sorry I've not been too great on assisting with the Big G. I guess it's easy to sidetracked and pulled to other things when if you stand still long enough. LOL

Yeah, I'd be up for working on another fleet ship if you're up for it. Just somthing to offer while people are waiting for the new Big G.

I can't wait to build it, I've been thinking about it for a long time.

I wasnt aware that user login was required!

BSG isnt my thing but now i'm told that it is images of the original version.
there is also a link to a zip file of all 300 images (500+ megs) in the first post.

but if you want to get the pictures (which are excellent) I would suggest registering, because reading how and also why they are there is not too high a price to pay for them :)

here is an example picked at random though
