The TFCTech Addon already does that. Too bad its whats causing .98 to breakDoh!
I think the ideal solution would be to add a new kind of "double plate" to the metal press for each metal, and allow these to be used in place of the tfc double sheets in every recipe. But that would probably be a lot of work.
Yes, but I think they can be filled using the bottler and railcraft steam.By the way I just crafted a steam-driven wingpack (which wasn't easy!), but it seems like there is no way to fill the canister to fuel it. Argh! (You did mention earlier that the block that fills those canisters crashes the game.)
