Unable to make items/blocks

Quote from Oneoutway

I can't make rubber using the unless it means rubber trees fresh cut wood. I am unable to make the dejuicer following that recipe unless the machine block and the leet block are different blocks then I can't make the leet block.

Crafting E-654 Rubber Extracted Rubber™ requires

1- Three fresh cut wood blocks

2- One E-654 Rubber Extractor Treetap™

This produces one unit of Extracted Rubber™

This was found to be highly inefficient and has been superseded by the Dejuicer-Device of Doom - D123 ™

Crafting the Dejuicer-Device of Doom – D123™ requires

1- Four Standard E-654 Rubber Extractor Treetap™

2- One Multi-Functional-All-Around-Ultimate-Usage-Circuit™

3- One Leet-Block M60™

Oh jesus, damn wiki with those understandable stuff...

Okay here we go : to get rubber you can do the following :
Have IC² (because that recipe with 3 rubber wood + treetap is IC1)
then,

Get sticky resin from rubber tree holes (those orange things on tree trunk, click just once and it will keep regenerating)
smelt that sticky resin on any furnace for one rubber OR use the dejuicer device of doom (extractor) and get 3 rubber from one sticky resin.

extractor recipe is : post above (ninja'ed me)
