Post Storm Dolly
I wanted a dolly that would be rock solid in hurricane winds, reliable at -60c, and still easily transportable, so built this out of CNC parts from eBay.
Travel length is approx 650mm / 26"
About $150 in parts.
Still one or two minor tweaks to make like countersinking some of the bolts, but basically done.

I guess weather proofing the electrics requires quite a lot of consideration as well?

Weight is about 4Kg / 9#
The electronics I use are pretty easy to weatherproof in a sealed container, the only exposed part will effectively be the motor which can be sealed reasonably well.

Very cool! That should remain straight and also keep the trolley form rattling around in the wind. Did you actually have experiences where high winds would wiggle the trolley on its track? My Stage Zero is pretty solid and the grip of the linear bearings on the sides can be tightened by tightening the screws that hold their aluminum angle to the flat trolley deck. Do you plan on adding mounting holes in its base for lag bolts to fasten it to the ice or ground? If you bring a portable drill and some expanding anchors it could be screwed down real good. Normally I wouldn't suggest that, but given all the effort that went into making the rest of it rock solid......

Those rails are very good got some from China recently a lot cheaper and a lot better the Igus which i will never use again. Only down side is a tad heavy i got the 16mm ones for my crane to ride on .
Slightly off topic but hey that's me and off topic seems more fun these days !
Just built this for a job sort of a dolly but its in fact a model mover for a very large animation puppet . Bit of a gimbal and slider really as you can see bit Heath Robinson but it does the job .

I`m trying to picture the scene: hurricane winds, -60°C (with or without wind chill?) and yet nothing landing on the lens to spoil the time lapse.

I think I`ll stick to the Alps in winter. Much the softer option!

Yup, without wind chill. Generally it is so dry in the winter that things don't stick much, and tends to get blown away, so it is not much of a problem. However the battery compartment and CF compartment getting packed solid with snow inside the camera can be a problem from the sheer force of the wind.
