(...) So you want to mount a camera on a flatbed and put it on a circle? If so you might want to make an arm that goes into the center, and put some weight on it and a single wheel or even one of those boat "glider pads" round 2*2 under it (as in (...) (21 years ago, 13-Oct-03, to lugnet.trains)

(...) wow, that's getting complicated. how about a 12v motor, at the center, with a platform built onto it. you get stability (by removing the bogey aspect), and simplicity. if need be, i can post a mockup, but somehow i don't see this as a problem (...) (21 years ago, 13-Oct-03, to lugnet.trains)

(...) Both ideas would work excellently for an external 360-degree pan, but once again I forgot to mention one thing: the subject is in the middle. To clarify: I'm doing a film where I have a cardboard "valley" full of sand. I want to do a pan all (...) (21 years ago, 13-Oct-03, to lugnet.trains)

(...) Here's a thought: Make a single "rail" out of 1x2 bricks, curved to the diameter you want. Build a wheeled support for your camera with a groove in it that lets you slide it along the bricks. Or (and I know this is blasphemous and all) buy (...) (21 years ago, 14-Oct-03, to lugnet.trains)

(...) Then, if the LEGO track radius is sufficient, my idea still would work, just put the arm on the outside, and definately use a wheel this time. Nothing visible within the track circle! (21 years ago, 14-Oct-03, to lugnet.trains)

(...) I'm not sure I understand that. Are you saying use two separate tracks and put the "outrigger" on the outer track? I basically want to circle an object (in this case a large one) with the camera. I'm not sure how an arm on the outside helps (...) (21 years ago, 14-Oct-03, to lugnet.trains)

(...) Good suggestion. I'm not sure I have the baseplates to keep it all together, but I'll think about it. I was given a large table in the basement to work this project on, so I have good room now. A brick ring is certainly feasible, if I have (...) (21 years ago, 14-Oct-03, to lugnet.trains)

(...) The arm on the outside, which has some weight on it, will prevent the car from waggling on the bogies, thus keeping it 100% steady on the track. See (URL) for a sample... (21 years ago, 14-Oct-03, to lugnet.trains)

(...) I think I'd use a bigger interior wheel, technic beams for the outrigger and put the weights (the big red things) midway between the wheel and the train car, but ya, that looks like it ought to be pretty steady, you've changed a two point (...) (21 years ago, 14-Oct-03, to lugnet.trains)

(...) That's a nice design, a good idea. Even though I can't use the LEGO track, I can adapt that method to use with my current setup. Thanks! Even though that method does require a perfectly level area (which I don't have), I've added crosshairs to (...) (21 years ago, 15-Oct-03, to lugnet.trains)
