Welcome back everyone! This will be a short update since most of what we have to show you are multiple coats of primer and sealer on the faux wall. Last we left you all, we were just about about to start that process. The next 6 images will be sort of a visual ASMR or whatever you want to call it?

Image

Image
Here it is all primed and ready for paint. We had a small issue with one of the bricks which took a day to fix, but other than that we are thrilled with the results. It does the job of pretending to be a cinder block wall.

Image
Next step is that we went back to the barn lamps and compared them to the reference. We discovered a few things that were not right. First we had to smooth some of the casting lines out to match the smoothness of the lights in the reference.

Image
Next, we noticed two other issues. First was the conduit box that's to the left of the lamps, but we'll get into that in a future post. The other was the mounting bolts to the lamp cages were different to what was on ours.

Image
We discovered that they are known as slotted fillister bolts. However, these aren't normal fillister bolts. These are actually a stupid rare variation called a "cone" or "pointed". Let's just say that we couldn't find them in the time frame that we wanted to. I am sure there's some dusty old warehouse somewhere that have these, but we've gone down that path so many times in this build. We're not doing that here or again for that matter.

Image
What we ended up doing was mounting these screws in a bit router, spinning them and using an air compressor with a cutting disc to grind them down to the desired level. We then had to put them through a tapping die to re-thread them

Image
To the left are the original screws that are counter sunk into the lamp cage. It goes in a groove that holds them onto the base. The middle bolt is what we ordered and the right one is a completed example.

Image
Here we are with the final result. They match perfectly and fit the cages the way they should.

Image

This is sort of where we are. We found a suitable conduit box that is very similar to what is seen in the reference. We bought one already that we were going to modify before we found the better match. The old one was returned and the new one was ordered. That is coming but what is next are the barn lamps. They will get primed/painted and mounted to the backdrop wall. We have the colors of paint picked out for the wall as well as the red for the rest of the unit. However, that won't come until we have the conduit box that mounts above the barn lamps. That's all coming very shortly. We are working on this daily now that we have the time. We'll probably be tackling the internal door stuff before we finish the wall.

Soooooooon!

I saw that someone posted a smaller-scale containment unit made of EVA foam on Facebook. What you’ve done here is beyond my capabilities but I’m definitely going to use it for references when I build my own. A small-scale foam build seems like it’d be the ideal option for me.

Thanks for all the nice comments everyone. We are currently in the process of painting up the barn lamps. I will have another update coming real soon, but I need to let the progress build up a little before that can happen. We are getting very close to paint. Sadly, we're waiting for an order of the small conduit box to arrive and you can probably already tell its held up due to the pandemic. We need that box before we can do final paint though. Anyways, here is a spoiler.

Image

I might post another picture later today if all goes well.

Awesome! We will be releasing a big free pdf of this build when its completed. That'll include all of our measurements as well as identification of parts and labels. Doing it out of foam would be no problem and i'm sure someone will start casting parts in resin, foam, etc.

That would be amazing!

So happy to see updates for this project!

It's been a few weeks since the last update so I thought it would be cool to give you all a small update. We've taken a small break because we were waiting for another part to arrive in the mail. In the last update we painted the barn lamps. We showed you that. However, we haven't shown them fully cured and reassembled.

Image
We decided to give them a dry mount to the faux wall to get an idea of the final product.

Image
This is when we all got really excited. We put a lot of hard work into this wall. To see the results we were striving for is one of the best feelings.

Image
This is one of those things that while it looks great in pictures, it does it no justice in person.

Image
Now, onto the part which we were waiting for. This is a small conduit junction box that is hiding to the left of the barn lamps. The black electrical and conduit cables mount into this small box.

Image
To give you some reference, here is this shot again:

Image
We can get started on this project again now that this part is in hand. Recently, I inherited some really amazing tools that will be immensely helpful with this build. I wish we had access to them in the very beginning, but it is what it is. Hopefully that will be a big help in making things run more smoothly and save us time? Anyways, today we will be measuring where this mounts to the wall, as well as figuring out where to drill all of the necessary holes for the conduit parts.

Look forward to our next posts in the upcoming week or so. In the meantime, I hope everyone is staying safe and continues to do so now that it looks like businesses are reopening prematurely. Be careful out there and wash those hands.

P.S. - Does anyone else see a spider in the reference shot from the film?

Having the lights there in-situ is really bringing that wall to life. I'm envious you have the correct models, I'd love to have a bunch of those just for general decor. :)

This build is simply amazing. I don't know how I didn't see it before. When do you expect to share the parts list? I am especially interested to know about the conduit connectors and that recessed knob in the control panel... they are driving me crazy

Thanks for the kind words. We do really appreciate it. I was going to give you the short answer to your question, but I guess I am delivering it in full. This isn't in response to you in particular, but I just feel the need to broaden the answer since it's common for us. Plus, it will segue into the recent road bump we hit.

We do expect to share the parts list along with the blueprints/measurements, labels, etc. once our build is done. When that will be I can't say for sure but we're still confident it will happen this year. We thought we were going to have extra time with the pandemic, but that only complicated matters further. Plus, our schedules and lives have been rearranged now that some of us are back to work. We're close to completion. Believe me. We even have all of the paint picked out.

One of the main reasons why we haven't given out a parts list is I have made the mistake is misidentifying parts. Before I found out what the thyristors on the trap box heat sink were, I thought they were ham radio relays. I posted about them in this thread. Little to my knowledge, some people went out and bought them (which aren't cheap as they go for around $50 each and you need 4 of them), only to have me discover the thyristors (which also aren't cheap) were the accurate parts. I got messages from a few people that were upset over that (not all but some). We had no clue some people were buying these parts up the second we dropped word. I still feel guilty over that so no more of that.

Alright, so here's a perfect example of that which I haven't talked about yet. I only recently discovered this within the last few days. Our last posted update had us showing off a 4x4x4 junction box that we just bought that the conduit cable on the ECU connects to. Well, I recently found a behind the scenes photo that reiterates the saying "One step forward, two steps back".

Image
You can see higher up on the photo and more of the prop. If you take a look at that box, it's obviously taller than 4 inches. It's either 6 or 8 inches in height. We need to dish out more money on a new box now but more research needs to go into finding a new match before we can do that. It's like, where was this picture 4 months ago? Why am I just finding it now? If any of you went out and bought a junction box for your build, hopefully you still have enough time to return it and for that I am sorry. This is basically one of the main reasons behind the veil of secrecy over parts. We want to be confident in saying the parts are all accurate once the build is complete.

I don't want to sound rude when I say this but the other reason behind it is we just want to be able finish our build first. We put the hard work into discovering and figuring all of this out. If we were to just hand it over prematurely, what kind of satisfaction will we feel in seeing parts go up in price, people rushing their builds and getting them done before us, etc? We're trying to be perfectionists at this and we have a desired end result in mind that we want to achieve. I know that sounds selfish but we deserve it. I can't begin to go into the behind the scenes stuff we had to do to get to where we are now. Lots of research, lots of mistakes, lots of lost time, huge headaches, empty wallets, etc. There are many factors and reasons why this build is going into its sixth year. I mean look at all the time it took for the fandom to get the proton pack replicas to look the way they do? It took decades! It's just a process that takes time if you want to do it right. When we do release our work to the community, we know future builds of this prop is going to change and evolve from that point moving forward. It's going to be exciting to see what happens post.

One thing that we have not ever mentioned is the prop business aspect of this. I'm not going to get into it too much because it can be ugly. Some people feel entitled in gaining exclusive right to knowing what these parts are now so they can capitalize in on the parts early to get a step ahead of the competition. To quote Danny Elfman/Oingo Boingo in saying there's nothing wrong with capitalism. That's perfectly fine. We've even discussed it ourselves (we might sell off some of our extras but we are not getting into the biz). It's already happened with the door handle for this prop. I don't remember who but someone already offered up a casting. That's perfectly fair game. What I am about to say is completely unrelated to anyone here or anyone in the community. Someone on another forum slipped into my PM early on, bullying and demanding that I divulge them manufacturer names, part numbers, NSN's, etc. All I could say to that dude was "Kick rocks, homie!". This info belongs to the community and it will be soon. Some of you might not like that (well, we've got some Canadian film board stuff we'de like you to take a look at) and to that I say "tough". We're only hoarding it temporarily for good reasons. Sort of like safe keeping. There are some minor selfish reasons for the time being but we're all going to know what it all is once this puppy is up to walking. Once our prop is done, I have no problem with sharing our hard work with you all and to this community.

I guess in closing, we have to stress that we wouldn't have been able to get this far without the help of other members here. I would say more discussion about this prop goes on in my inbox than it does here in the public forum. It goes well beyond that too. Help came from places we never would have expected. Some details that were thought to be lost were actually found and then some. All of it is appreciated and we are still committed to engraving the names of those who went that extra mile for us on a plaque that will go on the back of the unit.

As for build updates, they'll come soon. We are in the middle of a setback but one we hope to remedy quickly. We are so very close to completion. I'd like to say I can taste it but there is still some sawdust in the air. We want to see it done more than you guys know. Believe us! lol.

You guys deserve all the privacy and "selfishness" as you said. You've put in the work, and deserve to have all the fawning and awe-inspiring comments already, and that will come.
I'm sure we'll all be too busy picking our jaws up off the floor to jump on the build manual immediately, but whenever you do release it, we will all be BEYOND thankful!

Amazing job as always!
