you know you can use powercraft mod to make a factory like me my factory was making iron pickaxe's all what you have to do is place 3 iron in the elevator ( it has a private elevator) and some wood (note: you have to place the wood you have in the right place) and then wait close of the you will find a chest that you will find your iron pickaxe (there's other chest don't open it)

Fake. Sorry, Dosent work. Just burns my coal. It overloaded...really. All the redstone exploded. Just broke and became drops.

did you use a mod? because if you did not use a mod then its fake! its load with dimond!
plz if you im wrong plz tell me

Also one way to make legit coal blocks is to download the Custom recipes mod. Also if you want some challenge in making coal blocks to convert to diamond is to use the following reciple:

S = Cobble, L = Lava, C = Coal. So to make it use the following pattern

S C S

C L C

S C S

I should try to make a better version of this.. once i figure out how its built

@radio Just a mock up, really. It was the first working version i made of this thing. Also, I could make an automatic one that looks like its continually turning coal to diamonds...or anything to any other block.

@Teh Its my own pack, google "Tydoku"

Making into a sand to glass :D
