i lay the poles across the top of the overturned milk crate, in the centre of the crate. Sure, they fall off the crates if the horse hits the pole, but that's the case with jump cups on a standard too. Just jump off, fix jump, get back on horse, lol. If you've built your 'milk crate jump' level on flat land then you won't have any issue with the pole rolling off the crate by itself.
As far as building larger jumps with milk crates, I personally wouldn't. If a horse hit the poles on a 3 pole wide oxer built with crates, I see the whole jump flying all over the place, crates falling down, etc. not a good scenario!
