Not sure what to call it, but make for neat shots. I'm sure they have easier ways to do, but I got a couple of these huge bearing things, and thought this would be fun.
The alternative energy crowd has been using old brake drum assemblies for some time to make windmills...many which have been in service for YEARS....I see no reason why many of the instructions and designs couldn't be copied over into making this device.
You could always use a big heavy steel plate for the base, then have a post coming out of that with a bearing around it, then a small platform ontop of that post so the talent can still stand in the middle of the centre of rotation...
No they wouldnt, the platform would stay still as it would be ontop of the post thats part of the base plate. The bearing would allow the camera to rotate around whilst everything else stayed still...
You could always have a counterweight on the other side, maybe sticks out 2-3 feet flat on the ground (so its not in shot) with a counterweight so the base dosnt have to be quite so heavy.
Very cool. For me, $5k would be better invested in a steadicam. However, if the parts are already on hand or there are cheaper alternatives, it could be a great addition to any filmmaker.
I think the only reason he used the turntable bearing is because he already had it, and it was fit for purpose. There are other ways to do this though.
