I'm planning to create an automatic TNT cannon which can be reloaded without user intervention but I ran into a difficulty: the TNT needs to be reloaded into my gun. I can create a magazine but it takes up a lot of space.

Since I've been using FTB for a while I'm wondering whether it is possible to create/generate TNT blocks with this mod somehow?

I'm not super familiar with Feed the Beast, but isn't there an Uncrafting Table? You can probably use that to see what goes into making TNT, or at least come close to confirming that you can't. – Sconibulus Jun 27 '13 at 12:15
I know how to craft TNT but I want to automate it. – Adam Arold Jun 27 '13 at 12:26
Which mod pack are you using? What version is it? You can find the version by looking at the mod pack in the list, it is the number in the parenthesis, i.e. (v2.5.0) – tarper24 Jun 5 at 0:27

You can build the block using any method you see fit (fabricator, stamper, ME crafting).

Then to place the block, you should be able to do so using the deployer from RedPower.

Do you have any tutorials on this topic? – Adam Arold Jun 27 '13 at 12:25
Auto-crafting or deploying? – M'vy Jun 27 '13 at 12:50
The wiki ( have some video. Also any youtube search ( will probably help you. – M'vy Jun 27 '13 at 12:54

To elaborate on @M'vy's answer, you would essentially want the mods Applied Energistics and RedPower 2 in order to do this, as well as a mod that produces energy, such as BuildCraft 3 or IndustrialCraft 2.

You would want to find some AE Quartz and Quartz Dust in the world, and use that to make an ME Controller. This, when powered by EUs and/or MJs from another mod of your choice, is what controls your entire system. Never let this run out of power. Now you're going to craft either three Deep Storage Units or three barrels. Make three ME Storage Busses, and connect the Storage Busses to the controller using ME Cable. Fill the DSUs or barrels with sand and gunpowder. Fill the other one with some premade TNT as a placeholder.Now you want to get into the automatic crafting. Basically, you will set up a system where an ME Level Emitter redirects back into the system. Set it so that there is always a stack of TNT blocks in your system. Make an Assembler Chamber and connect it to your ME System with more ME Cable. Have some ME Export Busses connected to some deployers and a timer set to whatever time it should deploy TNT. Make sure all your Applied Energistics stuff is connected by ME Cable.

Note that you need a way of making sand and gunpowder, this will not get the ingredients for you, it simply autocrafts and deploys.
