Accelerator (asked for spoilers)

[Grishnare]

I've given up trying to work out how to get this thing going. Its not intuitive. Please explain it to me step by step. I tried getting chasers into the accelerator, which did nothing. I tried getting chasers into the top of the machines grates, which disolved. I tried getting water to the lava flow to create more steam, which I couldnt do.

I am fed up, just tell me how to do it exactly. No hints or clues please just how to do it.

Also this game is really hard to find info for on the internet because of its name.

*edit* this is after factory.
