How do you make a lever for the broken furnace in Pokepark?

When you enter the Lava Zone, there is a strange machine before you. Run into it, then it comes to life. So now when you dash into it, a chunk of gold or iron comes out pick it up and go to the other side or the map. Get the darker piece instead of gold. You see another wierd thing go to that porthole and you press 2 to check then make an iron bar then walk back to the lever and put it in dash to it then you can go to the shortcut. There is also another attraction with Rhyperior. Be sure to befriend all the Pokemon that can spin like a top (Hitmontop or others no Baltoy yet).
