Erez, Another variation is to buy a wheel barrow inner tube. They come in a variatey of sizes. Inflate it so it is just firm enough to hold its shape. Apply mould release to the rubber. Then wrap in glass and/or carbon. The wrap in packing tape that does not stretch. Increase the air pessure in the tube and this expands compressing the layup and expells excess resin. (I always prefer to use pressure over vacuum when it can be applied.)
When cured cut a slot in the side which has two benefits. First it allows you to remove the wheel barrow tube and second is it allows you to fit a tube (for spi pole) into the edge of the ring making a more compact snuffer.
It does not take long to fair and paint in poly urethane. All up weight around 300 grams. (0.3 kg)
I know that the voices in my head aint real, but they have some pretty good ideas. There is no such thing as a quick fix and I've never had free lunch!
