Super 8 Gripping: one example of a DIY car mount

Post by narri »

Hi.

We've been working on a short during the summer which you people have indirectly contributed to by helping me with a lot of questions. Thank you all for your help!

I'm kind of hoping to return the favor. We have one scene where the talents are driving an old Mercedes and having a bit of dialogue going on. We tried shooting the scene from the back of another car during our first filming session, with bad results. The picture was shaky, and worst of all, the reflections made it impossible to see through the windshield.

We're reshooting in a couple of weeks. We had to come up with a solution.

We came up with this monster:

I studied some professional models and the only thing that kept me back was the price. I simply couldn't afford the real ones, so I had to find out some other way of doing it.

The suction parts are used for carrying glass and can according to the manufacturer withstand weights of up to 100 kilograms (220 pounds) each. The rest of the stuff was bought from a very cheap construction market called "Biltema" ( the Ikea of all stuff mechanical ). The only actual camera part is from Manfrotto/Bogen(part 293) and I was lucky enough to get a showcase leftover version for 30€(~37 dollars). Total costs for the thing are somewhere around 60€ (~75 bucks).

It's steady, at least when the mattebox is removed. We also got a circular polarizing filter to get rid of the reflections. This will hopefully solve our problems with the scene.

Here are a few pictures with all the extra straps, batteries and plugs removed. It's a bit easier to distinguish the construction:

The only tools needed were a pair of wrenches, a screwdriver and scissors.

Hope this helps someone, comments on refining the construction and critique is always welcome.

Mikael.

Good work. I constantly marvel at the ingenuity of the shooters on this forum. How about letting us know how well it worked for you after your shoot.

looks cool. i've always been afraid of the suction cup car mounts. I'm sure they work fine, but the fact that it's basically just sitting there freaks me out. I went another route when making mine. I was looking at car mounts online one day and came across one that looked an awful lot like a bicycle rack for the car, and they were charging way too much money. So I decided to sacrifice my $29 vehicle bicycle mount, add a square plywood platform on it, and there ya go! I put the DV camera on it and drove it around the neighborhood and it worked great. In the pictures, obviously, is my Nikon R10 and that round eyelit screw that i put on the accessory shoe is to clip a cord with a caribeaner to the vehicle, just as a safety measure.

The monster looks fantastic.

How fast will the car be driven? Is this rig as rigid as it looks or is there any cushioning element that might absorb a small bump or two I wonder?

Can you tell me what make of mattebox you have on it too, please, as I am looking for one for my 4008?

Good luck with the road test!

At one time we had a Matthews Door Mount and your $29 rig is pretty much set up like the Matthews. Nice job.

What besides the tripod screw in the handle stabilizes the camera in that rig?!? My Nizo would shake itself to pieces! 8O

I assume that is directed to me? The tripod screw is actually the only thing holding the camera onto the platform, however, the screw I bought was a little longer than the typical tripod head which allows it to screw into the threads of the R10 a little deeper. Another idea I tried (but forgot to take a picture that day) was using one of those ratchet straps wrapped around the camera and under the platform. The combination of the screw and the strap made a surprisingly sturdy mount.

You camera mount guys are kewl!

Little rubber pad under the mounted camera would reduce undue vibration while still keeping it solid.

Cool, I've used something similar to hold lights, but never a camera. Just make sure you secure it all with straps. A vibrating thing with some leverage can probably easily pull much more than 100 kg. /matt

I thought it was about time I shared this photo since it's now topical.
This was posted a couple years ago on a friend of mine's website in Canada ( http://www.crewpix.com ) and caused quite a stir. These guys are filmmakers in Ottawa Canada who were hired to make a low-budget Saturn commercial.

This is how NOT to do a car mount:

Amazing... I love the piece of foam rubber, presumably so his feet don't scratch the bumper :)

Flatwood, I'll post the original shaky shoot along with the new one for some comparison. I really hope the polarization filter does what it's meant to.

Sooper8fan, I'm kind of scared as well to be honest, we'll have to put up some extra straps just to make sure it stays on. Your rig looks very nice, there's only one question that popped in my mind, can you tilt the camera? I guess you wouldn't need that for normal car/dialogue shots, but a tilt ability might give you more possibilities of showing off your nice rig.

Dr Smith, We're going to tow the Mercedes at about 25 mph on a small asphalt road. There's some rubber mat trying to work as cushioning under some of the critical tension points. I'm not sure if it's going to be enough though. It's very rigid when I remove the mattebox, The camera lens rests on the ledge in the front, and the 3/8 screw fits well into the Bogen piece. The straps are really needed, without them there's some vibrating evident. As Mattias pointed out, if the vibration gets in sync, the tripod screw might shake into bits, and the 200kg pull limit might be compromised.

The mattebox is a German Ewa from the 70´s, it was originally designed for 35mm still cameras. Some small rebuilding was necessary to get it attached to the Beaulieu.

Hope that helps. I'm off to buy some straps now, thank you all for your thoughts.

Unfortunately it isn't a joke. The banter that ensued after this photo was posted was incredible. It's worth a read:
