Description of the issue:

Observing:
Currently crafting the Pistol Barrel is done at the vanilla crafting table with three steel ingots in a horizontal row. This is a pretty generic recipe shape of a pretty generic material (many mods add steel) for a rather specific output (I know of no other mod that adds a pistol barrel that is crafted from an equivalent of three steel or iron).
This recipe conflicts with at least one other recipe I know of, which are Base Metals' Steel Plates. Plates are a very generic material. I have at least 4 mods in my modpack that add Steel plates that are basically equivalent to 1 steel ingot each (plus a little hammer durability or a little machine energy).

Considering:
Immersive Engineering has this cool Engineer's Workbench that has no recipe for 3 Steel ingots yet.

Suggesting:
Well, removing the crafting table recipe and adding an Engineer's Workbench recipe for it instead.

Lastly

I think that the "components" BluePrint would be most suited for this.
