I have just finished a new Vacuum Bagging System to replace my old fridge pump system.
Here are the images of the prototype to assist anyone contemplating a similar build...
The concept is based on a kit available from Veneer Supplies.com(in the US) but uses a few different parts including an SMC Electronic Vacuum Switch. This system allows accurate control of vacuum pressures without the pump having to run continuously on big jobs. The vacuum reservoirs store vacuum pressure which is retained with a check valve. This allows the pump to start under minimum load.
