To make armor and weapons you need ores - and lots of them. Therefore it is almost essential that you pair up blacksmithing with Mining.
1->25
35 x Rough Sharpening Stone
Mats Needed: 35x Rough Stone
As this recipe goes yellow at 15, I estimated that you'll need to use the recipe around 35 times in order to reach a skill of 25.
25->45
40 x Rough Grinding Stone
Mats Needed: 80x Rough Stone
45->75
30 x Copper Chain Belt
Mats Needed: 180x Copper Bar
75->90
40 x Coarse Grinding Stone
Mats Needed: 80x Coarse Stone
I have estimated that you will need to use this recipe around 40 times in order to reach 90, as this recipe is already yellow when you learn it from your trainer.
90->100
10 x Runed Copper Bracers
Mats Needed: x 100 Copper Bar
x 30 Rough Grinding Stone
100->105
5 x Silver Rod
Mats Needed: x 5 Silver Bar
x 10 Rough Grinding Stone
105->125
20 x Rough Bronze Leggings
Mats Needed: x 120 Bronze Bar
125->140
50 x Heavy Grinding Stone
Mats Needed: x 150 Heavy Stone
You should stop at 150 though if you reach that before making all 50, as the recipe goes grey at this point - then if you need all 50 later on make them at that point instead.
140->145
5 x Rough Bronze Leggings
Mats Needed: x 30 Bronze Bar
145->150
5 x Patterned Bronze Bracers
Mats Needed: x 25 Bronze Bar
x 10 Coarse Grinding Stone
To make these bracers, you will be using the Coarse Grinding Stones you made earlier.
150->155
5 x Golden Rod
Mats Needed: x 5 Gold Bar
x 10 Coarse Grinding Stone
Like the recipe above, you will be using the Coarse Grinding Stones you made earlier.
155->180
25 x Green Iron Leggings
Mats Needed: x 200 Iron Bar
x 25 Heavy Grinding Stone
x 25 Green Dye
180->190
10 x Green Iron Bracers

x 10 Green Dye
190->200
10 x Golden Scale Bracers

250->255
5 x Dense Grinding Stone
Mats Needed: x 20 Dense Stone
255->270
15 x Thorium Bracers
Mats Needed: x 180 Thorium Bar
x 60 Blue Power Crystal
To make these bracers, you will need Blue Power Crystals which you can collect yourself for free in Un'Goro. They are dotted all around the place and should be very quick to collect.
You will need to pick up this recipe at the auction house though - so keep an eye out.
270->295
30 x Imperial Plate Bracers
Mats Needed: x 360 Thorium Bar
To get this recipe you will need to do a quest. However, all you need to do for the quest is to hand in 10 Thorium Bars, so nothing epic.
Unfortunately, this recipe goes yellow at 290, so to be on the safe side, I suggest you collect enough materials to create 35 in total.
295->300
5 x Imperial Plate Boots
Mats Needed: x 90 Thorium Bar
Like the recipe above, you need to complete a quest in order to get this recipe. This one will require you to hand in 20 Thorium Bars.
300->310
10 x Fel Iron Chain Coif
Mats Needed: x 40 Fel Iron Bar
This and the following recipes are fairly straightforward - just collect lots of Fel Iron Bars and get going.
310->315
5 x Fel Iron Plate Belt
Mats Needed: x 20 Fel Iron Bar
315->320
5 x Fel Iron Chain Gloves
Mats Needed: x 25 Fel Iron Bar
320->325
5 x Fel Iron Plate Boots
Mats Needed: x 30 Fel Iron Bar
325->335
10 x Fel Iron Breastplate
Mats Needed: x 100 Fel Iron Bar
335->340
5 x Adamantite Cleaver
Mats Needed: x 40 Adamantite Bar
Same as the previous recipes, just moving it up a notch by using Adamantite Bars instead.
340->350
15 x Adamantite Rapier
Mats Needed: x 180 Adamantite Bar
For this recipe I suggest you collect enough materials to make 15, as the recipe goes yellow at 345.
350->360
30 x Adamantite Sharpening Stone
Mats Needed: x 30 Adamantite Bar
x 60 Mote of Earth
360->370
10 x Khorium Belt
Mats Needed: x 30 Khorium Bar
x 20 Primal Water
x 20 Primal Mana
A good alternative if you don't mind waiting to have the recipe drop in Auchenai Crypts is Felsteel Gloves. The gloves only need 6x Felsteel Bar to make and they also sell well.
370->375
5 x Khorium Boots
Mats Needed: x 20 Khorium Bar
x 15 Primal Water
x 15 Primal Mana
You do have another alternative again - you can try to get the plans for Felsteel Helm in Shadow Labyrinth which only needs 8x Felsteel Bar per Helmet.
