T Slot Aluminum

I always tried to find good materials to build the camera array with low cost. However, the only think I can only find is slotted metal at Low’es and Homedepot. These metals are very heavy, and are not easy to align the camera array either. Slide bar in the market (http://www.stereoscopy.com/jasper/slide-bars.html) is way too expensive.

Today I found T slot aluminum. http://www.faztek.net/downloads.html. This is very good to build staffs. With linear bearing, I can build a slider on the rail very quickly, and I could also add a fastener to the side of the roller to fix the position of the camera.
