use ingenuity first, it helps both of those skills succeed. Its like starting a synth with 60%complete and 100 dura plus you have 1 turn left of ing to use for whatever. It may not be the best strat but i made it myself cause i never got any help crafting and its been working for me.

also even though they say part and decorations they work on everything, i use them all the time.

and they do stack on ingenuity.
