I started out building a scooter just for the fun of it. I was hoping to get something to play around with in the quarry when I'm diving doubles. I ended up buying an old Tekna DV-3X, for cheap, to get a motor and a shroud. The 2 hardest things to get my hands on. Also got the inner workings out of it for the reed switches. My uncle got me a short piece of 10" PVC and I made up 2 end caps by laminating PVC 1x12s together. I have some pictures of the progress so far. I have to build the rest of the shroud mounts and then get some batteries to test it out. Hoping to run around 18 amp hour batteries. But will see how big I can go when I set the bouyancy I got o-rings from Mcmaster carr hopefully they are big enough. I will update as I get things done, test them out.
