Dear John,The problem with a vacuum cleaner is the vacuum pressure is too low. Vacuum cleaners are high volume, low vacuum. Epoxy is the only glue that may work, the trouble there is that you would need to let the vacuum cleaner run the entire time, which is hours with epoxy. You could burn up your vacuum cleaners motor doing this.Recorcinol is an excellent glue but is usually not used for veneering because it is deep purple which does not look good when you get bleed through and is very expensive. Its main purpose is for exterior waterproof situations, mainly used in boat building. It will also not work well at the low pressure a vacuum cleaner will pull.Iron on veneer and using contact cement for veneering are both what is used when you dont have the right tool, a press. Both give you questionable long term results and have specific problems. I might use iron on veneer to do an edge of a door that doesnt get any exposure but not on exposed surfaces. If there is no access to a press and someone really wants to veneer with it anyway my advise is to make sure your not going to build it to sell. At least in that case the builder lives with the results.SincerelyDarryl Keil: I have one of your systems, but was asked by someone if they could : set up a system using a shop vac. Do you know how much vacuum it : would create? Other glues that might not need as much pressure? Epoxy : or resorcinol? I haven`t seen you mention resorcinol for vacuum : veneering. Any reason to not use it? I was also asked about veneer : that`s backed with hot melt glue and applied with an iron. My thought : was that it will have the same drawbacks as contact cement - i.e. too : flexible and doesn`t penetrate the veneer or substrate. Thanks for : your time.
