Vacuum veneer pump
I have some veneer projects in the queue that will need the services of
a vacuum pump. I'm not really interesting in building one. What are some mfgs to look at. Any suggestions? Thanks in advance. |

Any suggestions? Thanks in advance. Check around auto repair shops. Many have older R12 vacuum pumps they no longer use. I picked up two for $20.

A couple of things I think you give up, relative to the costlier systems, are (1) the pump runs continuously, and that noise might be a concern; (2) it is a small pump, and it will take a long time to pump down a large bag & fixture. I wouldn't take the hand-operatoed version seriously for anything other than simple veneering of small work using PVA glue. Aside from the obvious difficulty pumping down a larger bag & fixture, the fact is that no system is entirely leak-free, so an application using a slow setting adhesive would mean you have to periodically pump down the bag. I built my system using parts purchased from joewoodworker.com, and have a system with decent capacity (a 4x8 bag and large bending form is no problem) using a regulated pump for about the cost of the pump & bag from Woodcraft. The OP didn't say what his application is, but he did say that he didn't want to build. -- Art |

Are you using the ventura system that runs off of a compressor? |

My SO has that vacuum storage system you see on the Home Shopping network. http://www.comforthouse.com/spacebag.html She has a couple that have stayed fully 'vacuum packed' for over two years. Some leak some don't. Hardly the same amount of vacuum used in a press. Much easier to keep a seal. Really? The pressure developed by the vacuum bag is the result of creating a pressure differential between the inside and outside of the bag. The pressure outside the bag is ~14.7 lb/in^2 (psi) at standard temperature at sea level. The absolute maximum pressure the bag can develop is 14.7 psi regardless of how good the vacuum is inside the bag. Sucking harder can't make it better. So if you have a partial vacuum that leaves a residual pressure inside the bag of 0.1 psi is this really a big deal? Is the veneer going to lay flatter with an additional 0.1 psi? And is it really that much easier to keep the bag sealed against a differential of 14.6 psi than it is 14.65 psi? |

Really? Perhaps you misunderstood. My point is that the common storage bags, emptied by a household vacuum cleaner, do not achieve the level of vacuum as is employed in a veneer press (by at least a factor of 2 or 3), and at the lower inside/outside differential, it is easier to maintain that partial vacuum. -- Art |

Unfortunately this not a moderated group, meaning everyone has access.
Worthy individuals as well as losers. Just get a good news reader that has good filter functions. I just ignore the losers and appreciate the worthy individuals that take time to reply in a thoughtful manner. |

The problem is the Wreck circle jerk of losers like Upscale and Balderstoned have driven almost every truly knowledgeable woodworker out of this group with their trolling. Funny how it's just you that is being trolled. I wonder why that could be? |

The problem is the Wreck circle jerk of losers like Upscale and Balderstoned have driven almost every truly knowledgeable woodworker out of this group with their trolling. It's a joke now. BTW. A newsreader that has good filtering is Agent found at http://www.forteinc.com/main/homepage.php. When one of the bottom feeders pops up in the newsreader add them to your kill file and you don't have to bother with their dribble. Just remember the saying, "You can never win an argument with an ignorant individual." They will not be smart enough to know they have lost and will go on and on........ So, again let me thank the ones that do contribute. |
