Mesa:

Hi-jacks welcome. You are correct I will need the info anyway. Natural birth seemed to describe; espeically compared tot he surgury option required now the top sheeting is glued in above the tank. Your fule tank section hatch looks like a good solution too.

For your main hatch sanding, did you sand away part of the ply? In my case, it looks like even a portion of the ply will need to be sanded to match the front portion profile. If you look at the photo above, you can see both ply and 1/4" stock sticking out past the profile.

Again, any guidance on how to taper this back towards the end cap?

Any comments on how sturdy your end cap was? Mine was very loose (aliphatic glue; after the fact, I thought maybe epoxy would have been better). I will post a photo with the extra support added later.
