I bought one pretty cheep. not wort my time to make one or it possibly not work correctly for whatever reason. but your guys did a great job at it for sure. I added a central shop vac to my shop. with drops at the machines,all the hoses drop into a holder that seals off the end. the std light switches are wired together so you can turn it on from each machine station eazely.works like a dream.just got to try to keep the long curley's out of it....I used std pvc pipe&fittings no glue just push togeather incase you do get a clog.works awesome.
