The canoe wants bulkheads! 
First batch of mix 
Trimming bulkheads, and cleaning up 
Patching the top edge of the canoe 
Fitting, trimming, fitting, trimming… 
We started running into a lot of balloons in our trimming… 
Placing concrete patches 
Cleaning out the stray foam pieces 
Edges look good 
One bulkhead done! 
Erin: we’re going to need to take like six inches off the top.
Nick: okay, I’ll just go for it.
Both: uh, there go all of our air pockets…
Bulkhead/swiss cheese 
We had a couple leftover balloons to put inside popped balloon pockets 
Mixing another batch of concrete 
We ended up stuffing the balloon pockets with the foam we chopped off 
Still mixing… 
Patching done, ready for bulkheads! 
Bulkhead patching almost done 
I guess it could look worse… 
We still had to place the third layer of concrete on the ends under the bulkhead 
Wait, our bulkheads are both 6″ too long? … let’s chop them down more… 
Fitted bulkhead 
Packing in the bulkhead 
Placing this goes way faster than the rest of the canoe 
One down, one to go 
Starting bulkhead#2 
One more mix! 
Cleaning up 
Finished canoe 
bulkheads look good 
And the humidifying setup is reconstructed. DONE.
