Buter Posted May 11, 2009 Report Share Posted May 11, 2009 If anyone has ever wanted a vacuum setup but been put off by the cost, fear not, a very cheap system can be setup quickly and easily. Mine consists of a fridge compressor and some premade and homemade bags. Purpose built bags can be a bit pricey but you can make your own out of many things if you're creative; I've got one made from a shower curtain. I have had to make some large ones for working with surfboards but a guitar sized one shouldn't be too expensive and would last a long time (I've done nearly a thousand skateboards in the same bag). Fridge compressors can usually be scored for free from a small appliance repair shop as they often have models not in use anymore. If I remember correctly, Joe woodworker has plans or a kit for wiring in a pressure sensitive on/off circuit but then you start getting away from the cheap and easy philosophy. If you want a vacuum clamping system (I haven't got around to doing mine yet, but soon come) an easy way is to run a decent sized pipe along your workbench (or the wall above, or underneath or...) with inlets tapped with non-return valves coupled with quarter turn ball valves in locations where you may want to use vacuum clamping. Once you've pulled vacuum in the pipe it will act as a reservoir and you can switch the compressor off. No need to buy specialized vacuum gasket material, just use a bead of silicone and let it cure and then you have a sealing surface - trust me, it works. Here's a top I did this afternoon Cheers Buter Quote Link to comment Share on other sites More sharing options...
