It's Cod Time!

OK, so I finally got around to getting some spray-foam to work on my codpiece some more.
Well, It started off pretty good, I cut some wedges out of scrap PVC to hold the top plate at the height I wanted and taped it down, as I knew the foam would want to push the piece out a bit from using the stuff in the past (waaaaay in the past)
Initially all looked good after about 15 minutes of dry time, so I left it to dry and picked it up the next evening...
I removed the tape from across the front... Off cam the tape, then I heard the slow creaking of the expanding foam and this is what it looked like after about 5 minutes of creaks & pops!


Talk about an expanding cod!

The thing blew up like a balloon (the inside and top both warped slightly and the top plate was pushed out a good 10mm from the PVC internal braces I put in there!

)
So I proceeded to start trimming down the foam and instead of removing all of the foam and starting over I cut out the foam on the lower peak (there were large air pockets here anyways) up to the front of the internal braces. I then cut out the foam between the braces and removed the braces.
OK, shape started returning to normal but the top plate was still a little too distorted, so I shaved slivers out of the remaining foam wedge to correct the shape using a fully extended snap-off razor blade.
Once I was happy with the shape again I re-taped the top plate down across the widest part of the top plate to the codpiece and from the peak of the top plate to the peak of the cod and re-foamed the front making sure to leave the channel that was between the braces open to allow for internal expansion and prevent the warping again.

This time it worked like a charm!
Here is what it now looks like after trimming it up:



I left a 2-5mm lip on all edges to give the Bondo a good surface to bond to once I get to that (hopefully this evening)

So the moral to the story...
Be careful when foaming your cod or it will blow up on you!
