Post DIY Detachable Dolly With MX2 Dolly Engine Compatible
Hi, My name is Ji Hoon Lee and I’m a photographer from Korea.

Recently, while working on timelapse project, I needed a simple portable timelapse dolly.

In my case, the first priority during timelapse filming was convenient portability. It was even more in desperate need especially when filming or photographing on mountains and in a distant wild(suburbs).

For these reasons I came to manufacture a detachable rail and the cart which are compatible with MX2 Dolly Engine and thought I should share it with those of you who might have experienced the same difficulties that I had

Also, I have designed and made a MX2 Dolly Engine Controller case of my own style

Image
Image
Image
It uses Heavy Toggle Ratch made in Germany so it can be attached and detached without any block outs to Aluminum Profile and Titanum Pin 30x60size(metric), Korean standard size, very quickly.
(Once the rail is attached, it is firm enough to hold a weight of a light person)

Image
Image
The cart is designed in bridge shape to fit the detachable rail and built using Autodesk Inventor, a 3D design tool.

Image
In making the cart, 10 high strength plaster bearing of Igus from Germany was used and has a micro stop switch.

Image
At the end of the rail, it was designed to quickly fasten and loosen the belt with a single screw knob. (Therefore, this belt clip works as a stopper wheel as well)

Image
At the bottom of the rail a mounting block with two separate tab of 1/4 inch and 3/8 inch are installed so it can be operated without a need of a tripod. (it is unnecessary for a tripod head so you can travel more lighter)

Image
Although the weight of the rail is similar or a bit lighter compare to the existing 8020 profile, the width is slimmer and the motor is installed on the bottom of the device. Therefore the advantages are the light weight of the device and the roomier moving area.

Image
As of now, I am using 2.5foot x 3ea and find no problem in stability nor in usage.

Image
In making MX2 Controller Case, I've used DIY Kit and exchanged LCD parts to fit my design. The first one is made in CNC function(process)of Unibody and the second one is made in 3Peace Aluminum CNC + Bending type.

Image
Image
All parts(rail, cart, battery, controller, belt, mini ball head, and two tripod..) Storage Complete in The Slik 1770 Tripod Case

Image

And finally here is a simple Timlapse video made using the device.



Thank you very much and good luck to you all!~

Nice dolly and even better video . Nice to see a bit of narrative rather than the usual collection of clips .

I will say WOW as well. That is a very nice way to join track sections. By building everything yourself, it became possible to have the trolley high enough to move past the fasteners which join the track sections. Your dolly is very easy to transport. Placing the fasteners on top and on the bottom of the track makes it very rigid. I am also impressed with the strength, which can support a light person. I see some of the night setups have a nice, long track using several sections. The bearings which ride inside the grooves in the track are clever. I haven't seen any other dollies with that feature either. There are a lot of new features in your dolly which others do not have. The two cases for the MX-2 controllers look beautiful. I don't think anyone who has built their own cases has done such a professional job with it. labeling all the plugs and the name on it looks very professional. You may have the problem that it looks so good, some people will not believe you didn't buy a factory-made controller. The video was great, especially the night scenes. Don't be offended by the comments from my friend, Displacement1. He built the most brilliant motion control dolly, but it uses an aluminum ladder as a track. He just wishes his could be carried around as easily as yours.

Very good. i quite like the somewhat differant look to your images. The colouration and lack of sharpness makes for a more abstract look. And the music, especially in the second half works well.
Oh, and the dolly looks most inovative.
