How would i use rf (redstone flux) in my machines?

i have some issue with the code, as in using java to edit values in code that cannot normally be set, or do not appear on the page. 

May someone give me some pointers where i can edit the values and functionality of a specific object? (or do i have to create my own type of armor base, and set the DURABILITY *** of armor equal to it? 

More related, i want to use redstone flux, a power used in many other mods for a machine i made called the "fuser". It currently fuses items together and i would like to make it so that when you press a button it causes a delay (like a furance) and then gives an output. Currently, you press a button and it instantly fuses two items together with no delay.

[Dont focus on the no-delay part, thats an easy fix]. its the redstone flux i am trying to get it powered by before that, so it can take x rf/t
