large, top heavy oncidium - solutions?

[Adrian]

hi all, I came into possession of a large oncidium species (varicosum i think). its in tip top shape and flowered last year. the plant is very big with quite a lot of it growing outside the pot. the pot itself is around 150mm. it has very long leaves which add to the instability. at the moment i have resorted ti wiring the pot to some of the bench otherwise it just falls over.
what is a common solution? I was thinking about putting the plant, pot and all, into a terracotta pot but i would have to get quite a large one to stop this bad boy from toppling over. maybe mounting would solve it?

anyway, very keen for suggestions, solutions etc..

thank you very much
