Step 7: Closing notes
Many modifications could be made to this design; the helmet could be sealed around the diver's neck or onto a dry suit to increase pressure protection and allow for greater depth, although it should be noted that this would make it more difficult for the diver to remove the helmet in the event of an emergency. The topside air supply, as stated earlier, could be eliminated and replaced with a self contained air refresher. You could mod it into an awesome steampunk helmet! The possibilities are endless! be careful, and have fun!
