Chest looks great
Foam building is my piece of cheese or my Dr.pepper... anyways I've messed with foam alot =D
I could give you a tutorial myself... but ill just try to explain acouple things really fast!!
#1- before you start building, find a pepakura file (ODST chest for example), then download the free version of Pepakura Designer (the pro version lets you save your work or changes you make to files) BUT the free version does the job
Once you download the free version of Pepakura Designer, simply remove all the "Taps" like throw them out... taps are pieces that you glue together (FOAM DOESN"T REQUIRE THESE)... And every time you see a "Fold Line" you must disconnect it!!..... So you end up with 100 small pieces...
Then simply print and trace onto your foam ( cut the foam piece out with box cutter ).... then you have 100 pieces of foam! I like to build as I go... but I've done both... .REMEMBER TO KEEP THE PAPER PIECES!! Numbers show where to connect the pieces...
This is what I did-- I'll try and find a video for you alittle later man
Keep up the good work!!!
