Engineering is widely known as the strongest profession for classic in terms of utility, but it’s not just good for thworing bombs, you can also make a lot of money from crafting them!
But Lazy, only other engineers can use the items, so your customers can already craft what they need!
While that is undoubtedly true, most players don’t want to sit around and spend tons of time crafting intermediate materials. Most of the relevant crafts require multiple different crafted materials. If you are late for raid, you’ll just pay the AH price for a stack of sappers and get to work.
Specialization
Engineers can specialize as either a goblin or gnome engineer. For goldmaking the choice has no contest. Goblin is required to craft Goblin Sapper Charges, which is the strongest DPS consumable available from engineering. If you have multiple characters then going gnomish on your main is quite useful for AQ to get the teleport to Gadgetzan, at least as alliance, but otherwise goblin reigns supreme for gold purposes.
The best recipes
There are a LOT of recipes that sell well from engineering, below is a table with some of them including the recipe source and what type of item it is.

There’s more
A lot of the various utility gear pieces from engineering will also sell quite well, so don’t consider this list exhaustive. There’s absolutely more value to be found. My TSM group contains some more items that I was able to sell quite profitable in classic the first time around, so get on it.
TSM Settings
Below is my TSM import for posting engineering items to the AH. It covers all the items I found profitable in classic, so take advantage of it!
