Alright, vansten’s guide is basically perfect. Here is what I do on any forge.
You need a maxed forging character. Use a diamond stack (that is, if you want to forge topaz, put a diamond tool in the top of the stack, topaz as next. It will use the diamond tools’ effectiveness). I only forge 4 tools at a time maximum. Let’s me go long if things get dicey. Use all 24 advanced centraforge coils. You need every ounce you can get.
Deck:
Effect gum
Longevity gum
Special gum
Vigor catalyst 2
Corrupt boon compound 1
Fate paste 2
Stability paste 2
Decon resin 3
Setting resin
Defect Removal Solvent 2
Here are my rules:
- if I get a boon that is wrong, decon and try again
- after I get the correct boon, immediately use vigor catalyst 2
- Fate paste takes priority over stability paste when vigor/stability are limited
Round 1/2: special gum
Round 3: stability paste 2
Round 4: fate paste 2
Round 5: corrupt boon compound 1
Decision point 1: if you got the “low blow” boon, keep going. If not, use decon resin and try again.
Round 6: vigor catalyst 2
Round 7/8: effect gum
Round 9: stability paste 2
Round 10: fate paste 2
Round 11: corrupt boon compound 1
Decision point 2: if you got the “devastating damage” boon, keep going. If not, decon resin and try again.
Round 12: vigor catalyst 2
Round 13/14: longevity gum
Round 15: stability paste 2
Round 16: fate paste 2
Round 17: corrupt boon compound 1
Decision point 3: if you got the “heavy duty” boon, you are in the home stretch. If not, decon resin and start over. 
At this point you should have three boons, no defects or defect points. It’s a good place to be.
You will do a cycle of:
Round 1: Gum (effect, special or longevity)
Round 2: stability paste 2
Round 3: fate paste 2
Round 4: corrupt boon compound 1
And vigor catalyst 2 on round 5-8. Then start back at one on THIS LIST. Don’t go over level 4 on special gum (this is the “all-rounder boon”) and try and get 10 in damage and at least 6 in durability. A 10 damage, 3x3, and 6+ durability is rank 330 if I recall correctly. That isn’t bad and you can make a stack of them in under an hour.
I’ve made up to 350s with this method and my “floor” is 320s.
It’s very reliable.
