I was hoping it was that simple
Anything special about the rubber membrane? Do I have to buy special stuff or just some heavy latex?

Ok, I ordered a parts kit from Joe WW for the deluxe venturi model and will be attempting at first to just glue bridges. But being the cheeeeepo old geezer that I am and since I'm also putting the vacuum source together myself, I thought I'd build the bridge clamp myself as well. I'm looking for pictures of your vacuum bridge clamps, material sources and any tips or info you may feel like contributing. Don Williams or "lets be eating pasta" I know you guys are out there and have the reputation of expert in this field.....so I'm askin fer help!! TIA |

John ol' Buddy ol' Pal, I don't have a pic of mine, but I built it simply out of birch ply with a rubber membrane, and plexi. Jammed a brass fitting from home depot in the side and sealed it up to keep from leaking. Oh, and some closed cell foam tape from home depot too. |

Hi John, Marine-grade weather strip tape works exceptionally well as vacuum gasket material. It's much heavier-duty than standard stuff. Mine comes from M-D Building Products, Inc., stocked by my local hardware store (remember those?) Here's a link: http://www.mdteam.com/ Best, Jim |

Hmmm....good idea. There's only 3 or 4 marine stores near where I work. Along with several high-end yacht makers... |

John, here's a couple of picts of the one I made several years ago. Latex rubber for the membrane. - McMaster Carr Acrylic for membrane protection. - McMaster Carr 0-ring cord stock for the membrane to wood seal. - McMaster Carr Caulking for support of the membrane in the corners. Closed cell faom rubber for the seal against the top. - McMaster Carr. The white stuff on the inside is a type of non-woven that ensures that the vacuum pressure is evenly distributed over the bridge area. without it you could choke off the vacuum in some areas by the membrane. Most any fabric would work. I suspect most forgo the fabric however.
