Fabric Nightmare

So since my last posts my colours have been modified slightly and i have finally raised the funds to proceed to the next step of the build which is locking in the core details of my fabric including colours, coatings, weights, cost etc. I am sure Katie slapped me in my sleep a few times because a lot of discussion happened concerning the optional coatings.

The whole discussion was sparked by my friend Mitch in Australia due to him receiving his fabric just over a month ago. He went for PU coating followed by UV which was on coated on the same side as the PU coating which doesn't help considering PU coating to my knowledge goes on the inside of the envelope.  So with this in mind i made some inquiries with our go to man for fabric Andy Wang. With much discussion and headaches in Katie's case i had finally decided on double sided PU coated 1.9oz without the UV coating (due to cost constraints).

The numbers i got from Andy:
Cost: 1.74USD/m 1.9oz Pu coated (both sides)
Weight (with extra coating): 1.92oz-2.06oz (yd2) or 65.10g - 69.85g (m2)
Total Fabric Weight: 48.119kg-52.06kg gross fabric weight
Total Weight: 75.638-79.579 kg

Envelope Weight (Projected number via dream program):

WEIGHT CALCULATIONS
Weight of fabric               : 48.119- 52.06 kg (including the overlap of the parachute)
Weight of Nomex            : 6.321 kg
Weight of tapes   (1)        : 13.200 kg
Weight of tapes   (2)        : 0.427 kg
Weight of tract. cord        : 0.374 kg
Weight of centr. cord       : 0.221 kg
Weight of command line   : 0.769 kg about without (with) a return pulley
Weight of crown line        : 0.499
Weight of cables              : 2.585 kg
Weight of crimpings         : 0.900 kg (32 crimpings)
Weight of 4 carabiners     : 1.000 kg
Weight of crown ring       : 0.500 kg
Weight of 2 pulleys          : 0.200 kg (without a return pulley, elsewhere, add a pulley)
Weight of the thread        : 0.524 kg
Total weight                    : 75.638-79.579 kg

Keep in mind these numbers are just estimates however in terms of weight its obviously heavier than Katie's 1.3oz 74,000 which is something like 65 kg's however 80 kg's doesn't seem to bad considering a 90,000 Kav is in the 110 kg range.
