I decided to have a go at my own slider design. Not original, just a lot of borrowed ideas from other makers out there. I went with metal conduit over PVC for the rails, as I preferred the strength to weight ratio. Not mentioned in the video is the fact that I added a piece of 3/16th x 2 poplar clamped and glued as reinforcement for the lengthwise piece. This is only necessary for mounting it on a tripod. Not really necessary if you just want to place it on a floor or table.
