Scanning the AH for crafted items I could make a quick profit on I saw that Titanium Rods were ridiculously high. So I made one with mats laying in my bank and broadcast in trade. Within a minute (and around 5 whispers) I'd sold it for 80g.
This got me thinking, how could I mass produce these cheap.
The answer as most of you would know is getting Titanium transmuted from an alchemist. The numbers I'll be running are for a non transmute spec (if you're lucky with procs you may get a lot more)
Titanium Rod - Spell - World of Warcraft
Saronite Bar: 1g50s each (smelted from ore)
Titanium Bar: 12g (8x Saronite Bar)
Total price for a Titanium Rod: 15g (price of a stack of ore)
Again broadcasting in trade I'd sold all 10 I made in minutes.
Cost: 10x15= 150g (and an extra 20g tip for the transmutes)
Sold for: 10x80= 800g
Profit: 630g
Of cause these numbers will vary from server to server. Could also get more if you put them on AH (making sure you don't flood it). It's nothing huge, but not bad for a few minutes work.
NOTE: I did a search of Titanium Rod on the forums and nothing came up, so as far as I'm aware it isn't a repost. Just wanted to contribute in any small way I can ;-)
