I was able to get some work done the last couple of days.
I put high-R foam between the stringers to block off for pour in foam... then poured the front section and didn't get as much expansion as I should have!
At around $100 worth of foam for that section, I had to wait till we had a 85deg day yesterday and I was able to pour out all the 60 cubic feet of foam into the hull. It is a real messy job, I used up a lot of buckets, stir sticks and vinyl gloves.
I need another 10 cubic feet of foam to even out the voids and fill around fuel tank.
