Greetings,
I'm not sure whether I've picked the right forum for this question ....... if you think there's a better forum for this post, please redirect me.
I've been doing some veneering using the Roarockit system that uses a hand pump to generate the vacuum. The system is OK, but it was designed for skateboard building, so the bags that the system uses are quite limited in size for doing furniture components. The hand pump is also slow to establish a vacuum, especially when using the bigger Roarockit bags. In general the Roarockit was a great way to get started in veneering, but I'm now looking to veneer larger pieces, and I'd like to be able to establish the vacuum a lot quicker than the hand pump is able to, and I'd like to hold the vacuum for much longer than the Roarockit system can.
I've looked at various web sites that talk about using various types of Vacuum Pumps to do vacuum bag veneering. I envisage that the Vacuum Pump might get used on only four or five projects per year, so I don't want to spend large bucket loads of money on a very occasional use tool.
A few web sites talk about using the Vacuum Pumps that Refrigeration Techs use to evacuate a refrigeration system when they are servicing it. The following link points to one possible unit on Ebay; http://ift.tt/1LHPMPd At $145 plus freight, one of these pumps might be a suitable solution. This one is supposedly rated at 3 cubic feet per minute, so I don't know how long it would take to pull a decent vacuum on a big 1000 mm x 2000 mm vacuum bag. They have another rated at 5 CFM that is still under $200. Does anyone use one of these pumps (or similar)?
Other web sites discuss re-purposing an old Refrigerator, Freezer, or Air-conditioner motor/compressor sealed unit. One advantage of this approach is supposed to be that a re-purposed refigerator sealed unit will be much quieter. From a cost standpoint, this option looks attractive if I can get a hold of a working sealed unit out of a discarded fridge. However, I can't find any specs on the flow rate for a re-purposed refrigerator sealed unit. Would it pull a vacuum quickly or slowly, and will it pull sufficient vacuum ?
So, what sort of Vacuum Pumps are other people using to evacuate Vacuum Bags, or to drive Vacuum Clamps?
Regards,
Roy
