Need help with roundel ring

OK guys, I need advice on how to line my cut holes in this plywood.  I have been unable to bend any regular 1/4 plywood at all, even soaked.  I tried balsa which snapped even wet.  I used the broken bits to experiment and got the smaller ones to bend some but there's no way to attach them to the support blocks because it's so soft.  I can nail it and it just tears to shreds. Below is an image of one of my balsa scraps nailed in but barely holding.  The clamps are only holding a flat piece at the base for this experiement, ignore those.  I got the idea for this from the pictures Mark had on his site from building the walls at the experience.  I know there is a way to do it but it's far far outside my skill range it seems.

Try bendy MDF (medium density fibreboard).

I agree with Tony.  Gets some 3mm thick (1/8") MDF and it bends quite easily.  If you can't or REALLY want to use plywood and have access to a table saw, you can try making kerf cuts to allow it to bend: Kerf-Cut-Bending-Lead.jpg

Just regular ole mdf (really thin of course!) should be just fine. Reviewing timerotor's videos for the walls used in the Experience, the texture of the surrounds look very much like MDF to me.
Kind Regards,

I found some pieces of "basswood" at Hobby Lobby (USA) that seems to be good. They only had it in 2ft lengths so it'll take a little bit for me to get some circles complete. I'll post some more pics once I get more done. It's kinda sloppy with so many nails and screws visible but it'll eventually get filled in and covered up lol. Btw, does anyone know what color grey is good for a TARDIS wall?

I would suggest looking at something called "Light Ghost Grey". If you've got the background theme for the Forum set for "Light", then the color of grey you see surrounding the window where you type in your comments is about that color. With the white of the type-in window against the background you'll be able to see the difference: not stark white, but also not too dark grey.

The color might go by a different name depending on which brand you use, so maybe print out a screen grab of the window if you like that background color, and try to match it to one of the paint chips that have at places like Home Depot or Lowe's, or even Sherwin Williams. (I think Williams can color match paint if they don't have it in stock. Also, if they mixed a paint wrong for someone and that color is close to what you want, you can usually get it dirt cheap. My wife was looking for a pale blue for the bathroom walls and went to Sherwin Williams because she didn't see anything she liked at HD or Lowe's. Williams showed her a color from a wrong mix and it was perfect. It was normally a $40 US gallon of paint and she picked it up for $5 just because they wanted to get rid of it!)

I hope some of this helps.

Backside of the piece of wall I'm playing with.  This is going to have a lot of screws, nails, and glue lol. I did get two pieces rounded and attached.  Just have to keep on going.  Messing around with stuff like this really makes you realize the dedication that Timerotor had in building his.  Suggestions welcome.[attachid]IMG_1566.JPG[/attached]

You can never have enough screws, nails and glue.  ;D
It looks like your plan will work nicely.

UPDATE: I even uploaded it from my PC instead of my phone and it still rotated my image! Sorry guys!

Well this has turned into a tall project.  It's within an inch of my garage ceiling.

As for the circle rings, slow project. The bottom half one is about 2/3 done around the arc. The lowest full circle is about 2/3 done as well. I haven't found any strips longer than 24" so it takes multiple sittings to get anything accomplished.  I like to think there is always an easier way than what I'm doing but no clue what it would be.

Looking good! I'm about to embark on this task too shortly.

My plan was to have whole length strips of 2mm hardboard and wrap this around the roundel gap. And instead of sitting on top of the edge as you have it, like Mark's (timerotors) video, have the length sit flush inside the roundel gap. IF that even makes sense...
Kind Regards,

David

Here's a little help with the image, Omar:
IMG_1582.jpg

One thing to try is once you get the image onto your computer, open it up, and even if it looks upright, still do a "Save As..." and overwrite the existing file when it ask you to. That will set the metadata and make sure the image is upright. It should post find then. (It's a complicated thing, and I think Bill (DoctorWho8) can explain it better than I can. He's got a post with info on that around here somewhere; I just can't find it to link to it.)

The project is looking really great so far. It's making me wish I had a wall with room to play with so I could try something like this. It would be a great way to add some mood lighting to a room.

I totally missed that part. Do you think it'd benefit me in any way to swap to the outer edge for my other circles?

Can anyone direct me to some type of yellow plastic that'd work as a roundel since I can't form the traditional ones? Light would obviously need to shine thru but nothing else.

Have you tried looking at Tap Plastics? (Just Google them.) They sell colored plastics and acrylics. You might find something there in the color that you like and they do have a wide variety to choose from. I think the square ones come in 2-ft by 2-ft which should cover your roundel openings with plenty of room to secure the plastic from behind. They do have other sizes if that's too large, so check them out. You might get lucky and even find some circles (they do sell circles as well).

I hope this helps. (If I knew of other places to look, I'd mention them, too, but this was the only place I've come across.)

Omar, I think the only benefit will be that you can put wooden blocks on the curves to stop it unnecessarily flexing - again, exactly how the original set was built and Mark's.

You can then use filler to cover the gaps.
