Well, Nuclear Reactors can cause more damage then any of that if they overheat...

Are you sure that you are logging in on the tekkit client with that account that you have brought minecraft on?

If it says Failed to login: bad login it means you have not got the paid version of minecraft. You gotta go to server properties and open it with notepad. Change the online mode=true to online mode=false.

I put down my quarry on my Tekkit sever and then i put 1-2 steam engines and power them. They move in the in-out motion but the frame of the quarry just wont start build. I have tried with Redstone engines aswell.
