What things would i need to build one?Can't help with hire, but suggest a cheap Chinese vacuum pump from eBay, or a used eBay pump of better quality, and a lash-up polythene bag may be just as cheap as any potential hire fees.
I've just made some vacuum pucks for clamping and am realising just how useful having a vacuum pump on hand is.
I used to use a large fertiliser polythene bag with a tyre valve fixed on with a good vacuum pump in secondary schools in the 70’s before we bought a proper Harefield bag. A cautionary note. PVA didn’t dry in the bag - we had to use synthetic resin - Cascamite or equivalent.Does anyone know wher i could hire a vacuum press from? The pieces I need to press are maily small (24" x 18").
I live in South Yorkshire.
