Engineering
List of Materials :
Hopefully you’ve taken mining as a second profession or you have access to a miner otherwise Engineering will be an expensive profession to take all the way to 450. I’ve worked some leeway into the guide, often by making extra when the recipe has turn yellow just incase you don’t get a skill point. This means that there maybe some left over materials by the end.
There are occasions when you might need to buy extra. The Gnomish Knife at the end is a prime example of this. I’ve also not included the materials need to make the epic engineering helm as it is dependant on which you want to make for yourself.

310320  10 x Fel Iron Casing 15 x 4 Elemental Blasting Powder 
30 Fel Iron Bar 30 Mote of Earth 15 Mote of Fire 
You need at least 5 casings and 25 powders but probably more due to Fel iron Bomb already being yellow at 320. So make at least 10 casings and 10 powders. If you haven’t managed to get to 320 you might want to risk moving on to the Fel iron bombs as there is a chance to make some points up. 
320325  10 x Fel Iron Bomb  10 Fel Iron Casing 20 Handful of Fel Iron Bolts 10 Elemental Blasting Powder 
This is already yellow but you would be very unlucky not to get 5 points from 10 attempts. 
325340  20 x 3 Adamantite Grenade  80 Adamantite Bar 20 Elemental Blasting Powder 40 Handful of Fel Iron Bolts 
Only make enough to get to 340 as it goes yellow at 335

370375  18 x 2 Volatile Blasting Trigger  54 Cobalt Bar 18 Crystallized Water

375380  10 x Overcharged Capacitor  40 Cobalt Bar 10 Crystallized Earth 
You’ll need 10 capacitors later so keep going passed 380 
380385  10 x Hammer Pick  50 Cobalt Bar  Only make enough to get to 385. If you’re a miner keep 1 to replace your pick and hammer. 
385390  8 x Explosive Decoy  8 Frostweave Cloth 24 Volatile Blasting Trigger 
This is one of the yellow recipes that uses the triggers, so only make enough to get to 390 
390400  15 x Froststeel Tube  120 Cobalt Bar 15 Crystallized Water 
You might not need all 15 so you can stop once you get to 400 and then come back to make more if needed for later recipes 
400405  5 x Diamondcut Refractor Scope  5 Froststeel Tube 10 Handful of Cobalt Bolts 

405415  15 x 24Saronite Bomb  65 Saronite Bar 15 Volatile Blasting Trigger

420430  15 x Mechanized Snow Goggles  120 Saronite Bar 30 Borean Leather 15 Eternal Shadow

435445  15 x Gnomish Army Knife  150 Saronite Bar 15 Skinning Knife 15 Minning Pick 15 Blacksmithing Hammer 
Stop when you get to 445 to make the your engineering helm (assuming you want it) 
445446  1 x Engineering helm example  Materials are dependant on what helm you want  I’m assuming that since you’ve gotten this far you will want the engineering helm 
446450  15 x Gnomish Army Knife  150 Saronite Bar 15 Skinning Knife 15 Minning Pick 15 Blacksmithing Hammer 
To get to the last couple of points is very expensive as the only really viable recipe to use is the Gnomish Army Knife which unfortunately goes green at 445. So just keep grinding them out till you get there. I would say at least 1520 might be necessary.. unless you are very unlucky. 
This really is the end.. honest
I hope you found this guide useful.
