I use a Festool vac to collect dust from my power tools. The problem I have is switching the power cord and vac hose to different tools. I wanted to hook up more than one tool at a time to refine workflow. After finishing a large hardwood job and switching the hose from tool to tool hundreds of times, I decided to tackle the problem with a few hardware store parts to make a very functional manifold that does the trick.

I uploaded a video of the project on youtube: http://youtu.be/6RrvMqoihi4
