modular body tubing

I don't know if modular is the right word here but we can pretend. I tried uploading the pictures but kept getting 'failed attempt'. I asked in the 'the watering hole' forum area and some people have said that the picture uploader is down well other say its working. I didn't feel like fighting with it so I made a video.
