Wow, very cool examples of what type of footage you can achieve with the SpiderTrax Dolly design. Here's another simple build video of how parts from a normal skateboard, Cheese Plate, and Quick release adapter were put together for those slider and rotational shots.
Two months ago, the video above also used Skateboard trucks and looks like a wooden base. This is definitely becoming a main stream tool for many DIY'ers.
Isn't it weird how I share these videos and information openly, while at the same time it's something that I need to sell? It's all good with me, because my main goal was always to share these ideas and inspire more creative footage. For those who weren't able to DIY and wanted something, I worked with a team to have parts professionally manufactured with solid aluminum, cut with Computer Aided Design, and special Anodized coating (not spray paint).
