Hi all,
Here's that round airlock I mentioned earlier. To go straight to the pics:
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=20672
1 and 2 show the outside, with airlock open and closed.
3 and 4 show the inside, with airlock open and closed.
5 shows the roof removed. You can see the how the arches are used here.
6 shows one side's walls removed, and the arches are shown more prominently.
7 shows the key to the arches SNOT. This is the bottom 1x4 in pics 3 & 4.
8 shows what's happening under the cylinder.
This works great - the airlock is snug, and moves nicely. It won't wobble
open on you. And it physically cannot be open to the inside and outside at
the same time when using 3 round panel pieces and this exact arch
configuration. I neglected to add tiling to the top of the cylinder to
"seal the hole" between it and the roof, but you can do that easily. Also,
sorry about the black - it's the only color I had enough of to do this, and
I still needed more (hence, the red).
The only real downsides to this are that it
(1) takes a lot of interior space in a small building. But, I sort of
solved that with the interior detailing, hiding the back/underside of the
arches.
(2) can only be made at a 45 deg. angle. In pics 1 and 2 you can see
clearly how I made the 45 deg. floor thingie to compensate this well.
LMKWYT!
-Chris

| (...) Now THAT is cool! Couldn't that be used as a docking mechinism? Remove the plates that stick out (what are they for, exactly?) and two of those corners would fit snugly, creating a small empty space in the middle. Great idea, Chris. -JHK (22 years ago, 1-Jul-02, to lugnet.space, lugnet.build)

| That is cool Chris! I'd just have one comment - it mightn't be as easy as you think to get a seal at the top - unless LEGO have made 4x4 tiles with round corner. There's no tile that would match exactly to the edge of the cylinder. However you may (...) (22 years ago, 1-Jul-02, to lugnet.space, lugnet.build)

| (...) That's magnificent! It reminds me of the "transporter" on my old Star Trek playset (wow, that was a LONG time ago--1977, I think) that worked on a similar principle.

| Chris, Great job. Now, if you lined the inside with sandpaper, turned it on it's side, and attached a motor, you could have a spiffy rock (or minifig) tumbler. - Sean (22 years ago, 2-Jul-02, to lugnet.space, lugnet.build)

| That's so cool!!! <gasping for breath> :-D Awesome idea Chris! I once had this Marvel Superheros action figure set that used a similar concept for elevator doors. Anyways, this has so many great applications. Can't wait to see what else you'll come (...) (22 years ago, 2-Jul-02, to lugnet.space, lugnet.build)

| Very cool...can't wait to see it appear on someone's capital ship! I wonder if the same concept could be applied using the smaller cylinders (4x4)in a similar manner to it's usage in Dan Jassim's Starshuttle? Do they make curves of that size? I'm (...)
