Hi John,

i have got a 4 liter container but i do not put parts in it. I am using the pump for extracting the air out of the resin (in the container) and to press the resin with the fibre into the mould (vaccum with the blue perforated foil, have a look at the handbook). The biggest parts i made this way had a length of 120cm (rc model boat) with one part moulds.
I made some smaller (lets say 3D) parts with two part moulds, the biggest ones were 15cm x 10cm x 5cm. I used highly fluid expoxid resin (HT2) and powdered carbon fibre. Worked ok for my application, wall thinkness was big enough to stabilize.
