So i've had more then a few conversations with people that have wanted to build a dolly and/or jib arm so i figured i would post a video so that anyone wondering how they might be able to do this would get some insight.
Its actually a pretty simple process, and fairly cheap too. The dolly only cost me 36 dollars to build but i bought all brand new skateboard wheels off ebay. Thanks to the ns member that was so kind to ship me 70 bearings to put in them. (i won't reveal his name so he doesn't get a lot of pm's from kids who want free bearings.)
This is a bit more difficult and a bit more costly, but if you're mechanical whatsoever you can probably do it.
download the video i made here, it doesn't go into huge detail, but like i said it's pretty easy.
i will ask the mods to please not move this thread to another forum because not as many people would see it probably...
