360VM-1

Here’s a more personal look at the 360VM Video camera slider with belt driven Crank. There’s no denying from the exterior that it has been influenced by the Kessler Pocket Dolly V1 which was based on IGUS rails. Don’t change the channel just yet. At closer inspection the 360VM slider does not appear to be using IGUS rails, and most importantly they are not using IGUS Drylin bearings. I’m not sure which extrusion this is or if it’s been completely custom made, but the biggest difference is the bearings used are large Teflon blocks. The teflon blocks wrap around the rail, so the carrier cannot be removed without tools. No worries about your camera falling off.

On one end, we see the crank pulley. The pulley handle can be removed and there is also a small guide hole which allows the crank to be ’strung’. Using heavy thread you can wind the crank and control the movement through string pulling as seen in Kessler’s old video here.

On the opposite end, we have a free wheeling pulley. Looking closer at the top of the end plate, there are several pre-threaded 1/4-20 mounting holes. This is an expensive addition for any type of manufacturing to be done without reason. Possibly it has been pre-designed to support mounting for future motion control hardware?

There are two different sizes available in 28″ (shown) and 38″. The rail itself is just over 3″ wide with 3/8″ and 1/4″ pre-drilled threaded mouting holes on each end and in the center. I’ve mounted a 717AH quick release to the center (shown below).

The Teflon blocked sliding carrier is very wide allowing better balance over the rails. The carrier only allows for a 3/8″ mount for use with a full sized Photo/Video head.

There are small rubber feet at each end of the slider so that it can be used without a Tripod. As you can see from the photos, there is still enough clearance for the quick release plate to remain on the rail. Since there are no adjustable legs for this slider, you would need to be aware of uneven ground. One options some slider companies use is the Manfrotto half bowl adapter. This adapter will allow you to quickly get your camera level even if the base is slightly uneven.

They provide a tool-less adapter for the Carrier that allows you to mount and remove your Video head without tools when it’s time to pack things away.

With only a 3/8″ mount, you will not be able to mount a camera directly should you require. Luckily Manfrotto has a small 3/8″ to 1/4″ adapter which will allow you to mount your camera directly or small ball head.

Surprisingly there are not very many Ready-Made Crank pulley sliders available. The ones that are available are still quite high in price. It’s highly possible to build your own belt driven Crank Pulley using the IGUS Drylin system, which works well for light to medium cameras. As noted earlier, the 360VM Slider is not using IGUS rails or the Drylin W bearings, and instead have moved to Teflon blocks which slide very smoothly with little to no noise (unlike bearing based sliders). So far excellent build quality, and by hand the system operates very nicely. I still have to load this up with a Canon DSLR and take her out for a test drive – possibly will have time tomorrow.
