Cardboard build.

[Delorean3610]

With Halloween coming up I want to have my car in the local parade, but I don't want to go through the entire process of changing the car. I think a cardboard mock-up on the back will suffice for a local parade.

What I'm asking for is some dimensions on some of the parts of the rear reactor. The exhaust fins and the plutonium chamber. I can look up the rest, and I work in electronics so I have spare parts everywhere.

Not going to comment on the accuracy compared to the screen used car, but if you're building out of cardboard I'm assuming that doesn't concern you much anyway

The CAD file will be a great starting point for your project. If you need any other info, feel free to ask on my facebook page. There are a great number of reference and build photos there.

We also have lot of other builders there using the same file for their full conversion projects and have been posting progress to the page.

Very cool to have the master chip in with his support/help!


I too am going to plan for something this halloween, but also use for parades. It seems like the "back" parts could be replicated quite easy with that CAD document. I would like to do the flux bands too though, still figuring out a nice temporary solution for those. Im thinking conduit and expanded metal.

It doesn't have to be super accurate for a parade. I mean I got away with this.

How did they let you use the A car in a parade? oh wait...

[Delorean3610]

Is there any application standard on a Mac that can open cad files? Or does someone have PDF/JPEG of the rear deck assembly with measurements?

[Josh]

you can open dwgs online, or download a program. I would recommend AutoCad 360, it is in the app store. No pre-installed programs on osx can open a dwg.

Here is my cardboard setup from many years ago. I just winged it for the most part.

That's pretty impressive.

That's pretty impressive.

Thanks! It was for an event at my work. I think my build budget was less than $100 (including the smoke machines). I built a 1:18ish DeLorean out of cardboard as a kid as well. Funny how things come around again.

The cad file didn't have measurements for the exhaust fins. That's all I need. I have a lot of cardboard, but without the fun measurements I can't do anything.

I would propose to get a print of a movie screen shot of the rear fascia measure it with your d rear fascia and try to compare n figure out the dimensions.

Its drawn on a 1:1 scale. You can measure it / insert dimensons

Here you go...

They should be 11x17 sheets at a scale of 3"= 1'-0"

That is awesome. Very impressive.

Just thought I'd post this since I'm getting "back in the swing of things" as it were.

I originally started with Egull's BTTF vents being made out of pizza boxes, as seen here:

Then, using 3x3 foot sheets of aluminum, I crafted two vents from that mock-up and have been driving around with them ever since. They've survived a steady 105 MPH without deforming, so needless to say they're quite sturdy! Here's how they looked when I was spotted on Instagram last week:

A couple relevant blog posts that show detail shots of how I managed to secure it to the louvers:

Tomorrow I'll be working on replacing the "star pattern" LED's with LED tubes bought from SuperBrightLED's to make it look better.

Neat fact: while a single piece of 2x1 foot aluminum doesn't cover the full top of the vent, it has two benefits: 1) it greatly improves aerodynamics by allowing the air to go straight through the vents (which is partially how it survived such high speeds), and 2) it sits ABOVE the rooflline, so rear visibility is entirely unobstructed. Here's a couple shots to show what I mean:

Note that the vertical portions are still visible, which is good since you can verify they're still there :P

One drawback to this though: if you intend on driving it all over the place with it installed (like I do), the louver struts need to be upgraded to stronger variants. They'll open, but I can feel it struggling the more I do it.

Wow. No offense, but those are MASSIVE! I'm blown away that the downforce at 105MPH didn't destroy the louver. I'd also be a little worried the cops might see those as obstructing the brake/reverse lights.

[ALEXAKOS]

Yes those are a bit too tall. The angle is right though;)

[Shep]

Wow. No offense, but those are MASSIVE!None taken -- that was by design ;)


I'm blown away that the downforce at 105MPH didn't destroy the louver.Me too, although I will say that they shake like crazy side-to-side, particularly when you're next to a semi truck and get all the turbulence. Looking into an additional piece of aluminum to go flat across the rearmost louver (with the vents in it) to help with that, since it seems to be sliding there.


I'd also be a little worried the cops might see those as obstructing the brake/reverse lights.Me too, which is why I mounted additional lights in the different sections. Top row is brake lights, second-to-top has sequential turn signals, and the bottom row has reverse in the middle, and parking lights in the outer. Second-to-bottom row is empty since that's the row I see through. Mimics all the stock taillight functionality to avoid trouble with the law (and I've had a few cops tailing me from time to time to verify this, but never been pulled over in it yet)


Yes those are a bit too tall. The angle is right though;)That's actually what I went off of, but it didn't look bold enough for my tastes, so I made them bigger. You can cut two of the side pieces out of one 3x3 foot piece of aluminum, but barely have any leftover.

Also, major, MAJOR note I totally forgot about: if you drive fast with them on, do yourself a massive favor and put some kind of cushion or weatherstipping or something on both the vents and the louvers. I managed to rub the paint off the louvers and the rear fascia, which Josh now has to repaint when I get around to it...

[Mark D]

those are HUGE!

[Josh]

size aside, the fact that you drive around with those on all the time is a bit crazy if you ask me!
